Unit 5 Graded Assignment

What ecological level is more specific than an ecosystem but less specific than a population?

• Community

• Habitat

• Species

• Biome

What are examples of secondary succession?

Select all that apply.

• An earthquake causes rocks to be exposed for the first time. Bacteria start to colonize the rocks.

• A volcano erupts and a new island forms in the ocean. Lichens start to colonize the new island.

• A mudslide removes most of the plant life from a habitat. Afterwards, some mosses from neighboring habitats start to move in.

• A severe drought kills most of the species in an area. Once the area gets more rain, new vegetation starts to appear.

• They allow light energy from the sun to reach Earth, but block heat energy from the sun.

• They allow heat emitted by the Earth to escape into space.

• They reflect heat emitted by the Earth, back down towards the planet.
