Question
If a disease strikes the snake population in the food chain shown, what will happen to the populations of hawks?
- The population of hawks would decrease
- The population of hawks would increase
- The population of hawks would stay the same
Hint:
In a food chain, one organism cannot survive without the other as its source of food will be lost.
The correct answer is: The population of hawks would decrease
- If a disease affects the population of snakes in the given food chain, then the population of hawks would decrease.
- The food chain refers to a series of organisms in which one depends on another as its source of food. If any one of the population in this food chain gets affected, then the whole food chain will be affected.
- Here, the rabbits are consumed by the snakes and they themselves are eaten by hawks. If the disease strikes the snakes, then their population will decrease. Hawks, on the other hand, survived by eating snakes. Thus, the population of hawks will also decrease as they will die because of no food for them.
At the same time, the population of rabbits in this food chain will increase because there would be no other organism feeding on them.
