I think that the plants in the food web have the greatest influence on the ecosystem because they produce energy for most of it. (a pyramid with 4-5 levels).
Which organism in the food web that you made has the greatest influence on the ecosystem justify your answer?
Producers because they directly control the numbers of other organisms in the ecosystem. The food in an ecosystem (wether the producers or the prey) directly control the numbers of the trophic level above them. The producers must be the biggest because they provide the energy for all other levels.
Which organism has the greatest influence on the ecosystem?
Foundation species
What 2 organisms are the most important to an ecosystem?
hands down the most important organism on this planet is marine algae .” Phytoplankton are tiny microscopic plants – algae – that form the base of the marine food chain. Phytoplankton is most abundant in colder waters where there is an abundance of nutrients. Image: California EPA.
What organisms do all ecosystem depend on?
An ecosystem is made up of all the living animals and plants and the non-living matter in a particular place, like a forest or lake. All the living things in an ecosystem depend on all the other things – living and non-living for continued survival – for food supplies and other needs.
What are 2 secondary consumers?
In temperate regions, for example, you will find secondary consumers such as dogs, cats, moles, and birds . Other examples include foxes, owls, and snakes. Wolves, crows, and hawks are examples of secondary consumers that obtain their energy from primary consumers by scavenging.
Are jellyfish secondary consumers?
Fish, jellyfish and crustaceans are common secondary consumers , although basking sharks and some whales also feed on the zooplankton.
What elements are missing from this food web what is their function to an ecosystem?
The elements that are missing from the food web are detrivores, decomposers, and quaternary consumers .
What is the importance of food web?
Food web is an important conceptual tool for illustrating the feeding relationships among species within a community , revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
What is in the ecosystem?
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts . Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity. Every factor in an ecosystem depends on every other factor, either directly or indirectly.
What are the 3 major functions of an ecosystem?
According to Pacala & Kinzig 2002, there are three classes of ecosystem functions: Stocks of energy and materials (for example, biomass, genes), Fluxes of energy or material processing (for example, productivity, decomposition Stability of rates or stocks over time (for example, resilience, predictability).
What animal is most important to the ecosystem?
According to the international conservation nonprofit Earthwatch Institute, bees are the most important species on earth. The declaration was made last July at a meeting of the Royal Geographical Society of London.
Which ecosystem is the most important?
The Amazon rainforest : the world's most important ecosystem.
How do organisms change their ecosystems?
Life cycle results in growth of reef structure, which provides food and habitat for many types of organisms. Changes existing ecosystems by building roads, schools, and homes . Move and store nuts, leading to trees growing in new locations.
How does an ecosystem start?
In many ecosystems, energy first enters the ecosystem from the sun . ... Plants are food for consumers, so the energy in plant tissues is passed on to organisms that eat plants. Predators get their energy by eating consumers. Dead plants and animals are food for tiny micro-organisms like bacteria and fungi.
How does the ecosystem depend on animals?
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.
