Question

state the different tropics levels in food chain

Answer 1

The various links or steps in a food chain at which the transfer of food and energy takes place are called trophic levels.
The producers form the first trophic level as they manufacture food. The primary consumers form the second trophic level, the secondary consumers form the third, and the tertiary consumers form the fourth trophic level.

In the above fig. Grass is the producer which is eaten by the grasshooper known as primary consumer. Then the grasshooper is eaten by shrew, secondary consumer and lastly shrew eaten up by owl, tertiary conusmer.

Answer 2

Think about the food you ate today. Did you eat any plant materials? Did you eat anything that when it was alive might have eaten another organism?

Organisms, including humans, are often classified by their feeding relationships. In other words, they are organized by who eats whom, and this classification system is called a food chain. A food chain is a sequence of organisms that feed on each other. Although the design of a food chain can vary by ecosystem, all food chains are made up of the same basic trophic levels. Trophic levels are the levels within the food chain where an organism obtains its energy.

In most food chains, there are five main trophic levels, but the number can vary depending on the composition of the ecosystem. Ecosystems with fewer species may have a food chain with three trophic levels, while an ecosystem with a large number of species is more likely to have a food chain with more than five trophic levels.
