What is the most abundant organism in a food chain

The given question is incomplete as there is no food chain given in the question, but based on the knowledge it can be said so that producers are present in abundant amount in every food chain.

Producers

Explanation:

The producers can be defined as the organism which have the ability to make food. This food is used by the other organism of the food chain as a soul source of energy.

They are huge in number so that they can produce enough food to meet the requirement of other organisms. Though all of the organisms are not directly dependent on producers ,some of them(carnivores) are also dependent on the organism eating plants(herbivores).

Producers→ primary consumers(herbivores)→ secondary consumers(carnivores)→tertiary consumers(carnivores).

Here, we can see that the all the organism are directly or indirectly dependent on the producers and they are abundant in every food chain.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
