Which statement describes the first changes in a forest that would follow a forest fire?

• A climax community is established

• New plants grow from seeds that the wind carries to the area

• New soil forms

• Pioneer species are established

Ponds and lakes are

• flowing-water ecosystems.

• wetlands.

• standing-water ecosystems.

• estuaries.

The chemistry of aquatic ecosystems is determined by the

• amount of salts, nutrients, and oxygen dissolved in the water.

• the number of other organisms present in the water.

• amount of rainfall the water receives.

• biotic and abiotic factors in the water.

What is one difference between primary and secondary succession?

• Primary succession is slow and secondary succession is rapid.

• Secondary succession begins on soil and primary succession begins on newly exposed

  surfaces.

• Primary succession modifies the environment and secondary succession does not.

• Secondary succession begins with lichens and primary succession begins with trees.

The series of predictable changes that occurs in a community over time is called

• population growth.

• ecological succession.

• climax community.

• climate change.

A large region characterized by a specific type of climate and certain types of plant and animal communities---

• population
• community
• biome
• ecosystem
