[Science Form 2] Food Chain & Size Of Population

Will a change in the size of one population affect another population in the same food chain?

Yes, it will. This is because populations within a food chain are inter-independent upon one another.

For example, where there are too many giraffes, there will be insufficient trees and shrubs for all of the to eat.

Hence, more giraffes will tend to starve or die. On the other hand, where there are a fewer giraffes, it means trees and shrubs in the area have more opportunity to grow to maturity and to multiply.

Fewer giraffes also means less food is available for lions to feed on and more lions may starve to death.

Hence, where there are a fewer lions, the giraffe population may increase.
