An animal with long thick fur might be found in
a cold habitat
because the fur would protect them from the cold.
What occurs when two or more living things need the same resources in order to survive?
Competition
is a relationship between living things that depend on the same resources. The resources may be food, water, or anything else they both need. Competition occurs whenever the two species try to get the same resources in the same place and at the same time.

What contributes greatly to the sustainability of an ecosystem?
By having a lot of biodiversity.
The biodiversity of an ecosystem
contributes to the sustainability of that ecosystem. The higher the biodiversity of an ecosystem, the more sustainable it is. … The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem.
How does biodiversity contribute to the sustainability of an ecosystem quizlet?
Why does biodiversity contribute to a habitat’s sustainability?
The more plants and animals in a habitat, the greater the biomass
, which is how habitats store energy. The greater the number of species, the more competition there is for food between predators, which sustains their populations.
What do you call to those animals that eats both plants and animals?
An omnivore
is an organism that eats plants and animals. The term stems from the Latin words omnis, meaning “all or everything,” and vorare, meaning “to devour or eat.” Omnivores play an important part of the food chain, a sequence of organisms that produce energy and nutrients for other organisms.
What is an example of competition between animals?
An example among animals could be
the case of cheetahs and lions
; since both species feed on similar prey, they are negatively impacted by the presence of the other because they will have less food, however, they still persist together, despite the prediction that under competition one will displace the other.
What are some things that an ecosystem needs in order to survive?
An ecosystem includes the ways these organisms live, feed and reproduce within that particular area. Ecosystems contain many components, but the four main things needed in an ecosystem are
plants, animals, rocks and minerals, and water
.
What are five things do ecosystems need to survive?
An ecosystem
must contain producers, consumers, decomposers, and dead and inorganic matter
. All ecosystems require energy from an external source – this is usually the sun. An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter.
What are five basic components an ecosystem needs to survive?
In order to survive, ecosystems need five basic components:
energy, mineral nutrients, water, oxygen, and living organisms
.
Which ecosystem likely has the highest biodiversity?
Species richness is greatest in tropical ecosystems.
Tropical rain forests on land and coral reefs in marine systems
are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
What kind of ecosystem is known as sustainable?
A sustainable ecosystem consists of various habitats and biological surroundings. Explanation: A sustainable ecosystem can be defined as
a biological environment
.
Which ecosystem is likely the most sustainable?
The forest ecosystem
is most sustainable because most of the animals can eat other organisms. The food webs below model relationships among organisms in two ecosystems.
What describes an ecosystem with high biodiversity?
Ecosystems that have high levels of biodiversity have a large number of species,
complex food webs
, a variety of ecological niches, increased genetic diversity, and abundant resources.
Which biome has the largest number of species of plants and animals highest biodiversity )?
Tropical rainforests
support the greatest diversity of living organisms on Earth.
What effect do invasive species have on the biodiversity sustainability of an ecosystem?
Invasive species are capable of
causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats
. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
What kind of animal eats plants?
Animals that eat only plants are called
herbivores
. Deer, grasshoppers, and rabbits are all herbivores. There are lots of different plants and lots of different herbivores. Some herbivores eat only part of a plant.
How does competition of living organisms like plants and animals normally occur in an ecosystem?
Competition will occur between organisms in an ecosystem when their niches overlap,
they both try to use the same resource and the resource is in short supply
. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.
Why do animals eat plants or other animals?
Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
Animals cannot make their own food so they must eat
plants and/or other animals.
What do we call an animal that eats other animals?
A carnivore is an organism, in most cases an animal, that eats meat. A carnivorous animal that hunts other animals is called
a predator
; an animal that is hunted is called prey. … Many carnivores get their energy and nutrients by eating herbivores, omnivores, and other carnivores.
What are 5 examples of competition?
Types of Competition and Examples
Plants compete with each other for light exposure
, temperature, humidity, pollinators, soil nutrients and growing space. Microbes compete for chemical substrates. Animals fight over territory, water, food, shelter and prospective mates.
How does competition affect the number of organisms living in a habitat?
Intraspecific competition can serve as a regulator for population size. If a particular source of prey, or abiotic habitat feature is not readily available, then
competition for the ones that are will be heavy
. If the requirements are scarce enough, this will cause the population to remain stable, or decrease.
How could animals and plants respond to seasonal changes in an ecosystem?
Sometimes animal adaptations are triggered by weather and seasonal changes. … Some plants become
dormant
and some animals undergo changes to prepare for the winter. Some animals collect food to store during the winter months and others hibernate, migrate, or grow thicker fur.
How do plants animals and other organisms keep the biotic community alive?
Plants and animals benefit each other as
members of food chains and ecosystems
. For instance, flowering plants rely on bees and hummingbirds to pollinate them, while animals eat plants and sometimes make homes in them. When animals die and decompose, they enrich the soil with nitrates that stimulate plant growth.
What different kinds of organisms can you see in each ecosystem?
Ecosystems have lots of different living organisms that interact with each other. The living organisms in an ecosystem can be divided into three categories:
producers, consumers and decomposers
. They are all important parts of an ecosystem. Producers are the green plants.
What are the five basic needs of animals?
Background Information. In order to survive, animals need
air, water, food, and shelter
(protection from predators and the environment); plants need air, water, nutrients, and light. Every organism has its own way of making sure its basic needs are met.
What are the 4 main components of an ecosystem?
- Abiotic Substances:
- Producers:
- Consumers:
- Reducers or Decomposers:
What type of ecosystem do we live in?
Which ecosystem do we live in? We live in
a terrestrial ecosystem
. This is the ecosystem where organisms interact on landforms. Examples of terrestrial ecosystems include tundra, taigas, and tropical rainforests.
What is ecosystem its types and components?
An ecosystem can be categorized into its
abiotic constituents
, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members.
What do all living organisms have in common?
All living organisms share several key characteristics or functions:
order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing
. When viewed together, these eight characteristics serve to define life.
Why do animals need sunlight?
The energy from the sun is transferred from plants to animals when animals eat the plants. Animals also benefit from the sun’s effect on their bodies, because
sunlight on skin produces vitamin D
, which is important in the formation of strong bones. Animals also get vitamin D by eating plants.
What species can live on bare rock?
Pioneer species are likely to include
bacteria and lichens
that can live on bare rock. Along with wind and water, they help weather the rock and form soil. Once soil begins to form, plants can move in.
Which ecosystem would be more likely to survive if a disease killed the grasses?
Which ecosystem would be more likely to survive if a disease killed the grass?
The forest ecosystem
, because most of the animals can eat othe organisms.
What organisms are common pioneer species?
Fungi and lichen
are the most common pioneer species in primary succession because they have the ability to break down minerals to form soil and subsequently develop organic matter. Once pioneer species colonize the area and start to build soil, other species — like grasses — begin to move in.
Which ecosystem likely has the highest biodiversity quizlet?
Large ecosystems always have higher biodiversity than smaller ecosystems. A large area of a
forest
will likely have higher biodiversity than a smaller area of the same forest. A half acre of rainforest would likely have greater biodiversity than a full acre of desert.
Which ecosystem has the greatest biodiversity quizlet?

the rainforest
because it is located near the equator and has a perfect climate for a variety of organisms.
Which ecosystem is known as giant permanent pond?
Which ecosystem is known as giant permanent pond? Explanation:
A lake ecosystem
functions like a giant permanent pond. A large amount of its plant material is algae.
What features make ecosystems sustainable?
- Energy availability – light from the sun provides the initial energy source for almost all communities.
- Nutrient availability – saprotrophic decomposers ensure the constant recycling of inorganic nutrients within an environment.

is an example of Ecosystem diversity. Rivers include fish, mussels, aquatic insects and a variety of planets. Ecosystem diversity explains the interaction between living organisms and physical environment in an ecosystem.
What is habitat diversity?
Habitat diversity refers to
the range of habitats present in a region
.
What advantages does a habitat with high biodiversity have?
Greater biodiversity in ecosystems, species, and individuals
leads to greater stability
. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
Which ecosystem likely has the lowest species diversity?
Low species diversity :
The tundra biome
has the least biodiversity, but the northern coniferous biome also has low species diversity.
