A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2,
carnivores
at level 3 or higher, and typically finish with apex predators at level 4 or 5.
Which of the following is the highest trophic level in an ecosystem?
Notes:
Omnivores
constitute the highest trophic level in an ecosystem. Omnivores are tertiary consumers and feed on both plants and animals. Decomposers feed on all the trophic levels.
Which organism in the food web below is at the highest trophic level?
The fifth trophic level contains organisms known as
Quaternary consumers
or Apex predators. These organisms consume organisms in the consumer levels below them and have no predators. They are at the top of the food chain..
Which of the following is the highest trophic level organisms in grassland food web?
Which of the following is the highest trophic level organism in grassland food web? Explanation: In grassland trophic level grass is
the producer
. Grasshopper belongs to primary consumer.
What are the trophic levels in a food web?
All of the interconnected and overlapping food chains in an ecosystem make up a food web. Organisms in food webs are grouped into categories called trophic levels. Roughly speaking, these levels are divided into
producers (first trophic level), consumers, and decomposers (last trophic level)
.
What is the lowest trophic level?
The first and lowest level contains
the producers, green plants
. The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
What are the 7 trophic levels?
- Plants and Algae. Plants and algae comprise the lowest level of the trophic system. …
- Primary Consumers. Herbivores belong in the second level of the trophic system. …
- Secondary Consumers. …
- Tertiary Consumers. …
- Apex Predators.
What are the six trophic levels?
| Trophic Level Where It Gets Food | 1st Trophic Level: Producer Makes its own food | 2nd Trophic Level: Primary Consumer Consumes producers | 3rd Trophic Level: Secondary Consumer Consumes primary consumers | 4th Trophic Level: Tertiary Consumer Consumes secondary consumers |
|---|
What is the 4th trophic level called?
-Fourth trophic level:
Tertiary consumers
come under the fourth trophic level of the food chain and are constituted by the top carnivores. So, the correct answer is ‘tertiary consumer. ‘ Note: -The first trophic level is primarily occupied by phytoplankton and plants (grass and trees).
Which is the first trophic level in a food chain?
All of the interconnected and overlapping food chains in an ecosystem make up a food web. Organisms in food chains are grouped into categories called trophic levels. Roughly speaking, these levels are divided into
producers
(first trophic level), consumers (second, third, and fourth trophic levels), and decomposers.
Is grassland an ecosystem?
Grassland Ecosystem is
an area where the vegetation is dominated by grasses and other herbaceous (non-woody) plants
. It is also called transitional landscape because grassland ecosystems are dominated by the grass with few or no trees in the area where there is not enough for a forest and too much of a forest.
What is the correct food chain?
The process of transfer of energy from producers through a series of organisms, i.e., from primary consumers to secondary consumers and from secondary consumers to tertiary consumers by process of eating and being eaten constitute a food chain. The correct food chain is
phytoplankton >> zooplankton >> fish.
Which is true of a food chain *?
– Food chains
initiate with producers
. A producer uses both solar energy and chemical energy to convert organisms into usable compounds. – The organisms which eat others are known as the Consumers. All participants in a food chain are consumers except the first those produce.
What is food web examples?
A network of interconnecting food chains in a natural community of different organisms is called a food web. Example of Food Web. Consider
six food chains
which are interconnected to form a food web. The food web begins with plants and ends with the top carnivore, the vulture.
What is food web explain with diagram?
A food web is a
diagram of the links among species in an ecosystem – essentially who eats what
. A food chain shows only the organisms that contribute to the diet of the top consumer.
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.
