Question

question 13 some animals are fussy eaters. for example, the diet of blue whales mainly consists of small shrimp - like animals called krill. in fact, a blue whale eats up to 4 tons of krill a day! explain why animals that eat only one type of food are at greater risk if there is a change in their ecosystem.

Explanation:

These animals have no alternative food sources to rely on. If their single food type is reduced or eliminated by ecosystem changes (like krill population drops from ocean warming, overfishing, or pollution), the animals cannot switch to other prey. This leads to starvation, population decline, or even extinction, as they lack dietary flexibility to adapt.

Answer:

Animals that eat only one type of food have no dietary backup. When their sole food source is threatened by ecosystem changes (e.g., krill populations declining due to ocean shifts, pollution, or loss of krill's food supply), they cannot switch to alternative prey. This leaves them vulnerable to starvation, rapid population loss, or extinction because they lack the flexibility to adapt their diet to the changed environment.
