Question

Which one of the following has the largest population in a food chain?
A) Producers
B) Primary consumers
C) Secondary consumers
D) Decomposers

Answer 1

The food chain is a straight sequence of organisms by which nutrients and energy transfer from one organism to another.
In a food chain, each organism engages a different trophic level, defined by how many energy moves separate it from the basic input of the chain. Producers are placed in the beginning of a food chain.

Complete answer:
A) Producers - Producers are the base or support of the ecosystem. They are common plants but can be any organism, who can make their own food, like some bacteria. They cannot be the largest populations so the answer is incorrect.
B) Primary consumers - Primary consumers are herbivores that ingest the producers. It is also an incorrect option.
C) Secondary consumers – they eat primary consumers. So this is the wrong option.
D) Decomposer – Decomposers are from the largest population in the food chain. These are the organisms who Have a meal on the dead and decaying matter and break down their complex compounds into simple forms. These are bacteria, fungi, and several other microorganisms. They made an important part of the food chain. They break down the organic matter by freeing carbon and other nutrients that are beneficial for their growth and the development of plants.

The correct answer is ‘D’ – Decomposers.

Note: Consumers of a food chain are living creatures. Who eat organisms from a different population. The four types of consumers in ecology are herbivores, carnivores, omnivores, and decomposers. Consumers have important roles to play within an ecosystem such as balancing the food chain by keeping plant populations at a reasonable number.
