Write various steps of a terrestrial food chain of four trophic level?
Answers
A food chain is a chain which highlights the relationship between producers and consumers. It starts from the plants or the producers and ends with the decomposers. When the food chain happens among the organisms who are found on land habitats are known as terrestrial food chains. Deserts, grasslands, and forests are some of the land habitat regions. The number of steps of each organism from the start of the food chain is termed as a trophic level. Plants are on the first step of the trophic level, herbivores in the second and it finishes with apex predators. Only 10% of the energy passes from one trophic level to another.
We can classify the food chain in 4 tropic levels according to their food items and dependency.
Steps of a terrestrial food chain of four trophic level:
Level 1: Plants and algae are involved in this group and they make their own food.
Level 2: Next level is herbivores who eat plants. They are also called ‘primary consumers’.
Level 3: Next level is carnivores who eat herbivores. They are called ‘secondary consumers’.
Level 4: Last level is carnivores that eat other carnivores. They are also called tertiary consumers.
