In a population of predator and prey it was seen that when the prey population was numerically high the predator population consumed more and more prey. This is because the predator population

Solution

The correct option is B responds functionally
A predator is an organism which gets its food from the host after killing. It does not live in constant association with the host and this is known as predation.
The predator population works according to the prey and help in keeping the prey population in a check. In absence of predators, the population will increase immensely and will affect the normal ecological balance.
So, the correct option is 'responds functionally'
