Food Chains

A farmer grows Plant A in his field. Animals B and C are also found in his field. They form the food chain below.

Plant A Animal B Animal C

The following graph shows what happened to the populations of A, B and C when the farmer used a pesticide to get rid of Animal C.

Process skills: Observing, Analysing, Inferring

Time0

Number of organisms

a. Identify which line represents which organism. [3 marks]

b. What would happen to the population of Animal B after the farmer harvests

his crop? [1 mark]

Hint:If the whole population of

Animal C died, how would Plant A and Animal B be affected? Would there be an increase or

decrease in their number?
