Frogs often live in freshwater ponds where they feed on insects and lay their eggs in the water. Sometimes they are eaten by snakes. Frog would leave the area if -

• there were more insects.
• the snakes all died out.
• the water in the pond dried up.
• there was a little more rain.

All of the following are changes to an environment that could help an animal thrive EXCEPT-

• more of the kind of plants the animal eats.
• fewer predators that eat the animal.
• less rain during the spring and summer.
• removal of animals that eat the same food.

How could a forest fire help some organisms? A forest fire could help –

• remove the trees that birds use to build nests.
• clear dead plant to allow new plant to grow.
• scare away small mammals that are food for wolves.
• burn the organic matter from soil where worms live.

The chart below shows population changes after a recent flood. The information in this table shows that floods –

• are harmful to all species living in the habitat.
• cause changes that help some species thrive.
• result in large temperature changes.
• make populations of most species increase.
