Food Chain - 6th class

Food Chain - 6th class

A grasshopper eats a green plant, a frog eats the grasshopper, the frog is eaten by a snake, and the snake is eaten by an eagle.

This chain of events is called a food chain. A food chain shows

how each living thing gets its food in a particular environment.

                                  The study of food chains also shows us the interdependence of various organisms in that environment. In a grassland, the following food chain exists:

                                           grass ------> deer--------->lion

A typical food chain in a pond is:

algae(small pants)--------> small fish----------> large fish

Note that all food chains begin from green plants. What does this mean?

It means that all animals are dependent on green plants for food - either directly or indirectly.
