考试真题

A strong link is found between two species when a predator sticks to one prey species.

And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover.

And unplanned human activities have proved the idea of top-down control by top predators to be true.

If a predator can eat several species, it can survive the extinction of one of them.

In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species - including species they did not directly attack.

In the ocean, we fished for top predators such as cod on an industrial scale, while on land, we killed off large predators such as wolves.

It is thought that they are capitalising on their predators天敌fleeing to quieter areas.
