Module 8

A simple food chain

To have an understanding of a simple food chain

All animals and plants need food to remain healthy and have enough energy. Plants have the unique ability to manufacture their own food. For this, they use sunlight, carbon dioxide from the air and water and minerals from the soil.

All living things need food manufactured by green plants. The different parts of the food chain are like the links of a chain: if one link is missing, the chain is of no use until it is fixed. Each part of the food chain is important for the existence of the ecosystem.

The following food chains are faulty. Correct them:

Maize, sun, farmer, egg, hen

Table 1
         

Cow, boy, sun, grass, milk

Table 2
         

Lion, antelope, grass, sun

Table 3
       

Raptor, sun, mouse, wheat

Table 4
       

Now make your own food chain
