Barnacles are animals that cannot move. In order to get food, they attach to whales and catch any floating plankton in the water. The whale is neither helped nor harmed in the interaction. What type of symbiosis is this?

In the woods, there are ducks and mice. They both compete for grasshoppers as the only source of food in that area at that time. The ducks outcompete the mice, and the mice die out in that area. This is an example of:

• Neutralism

• Commensalism

• The competitive exclusion principle

• Mutualism

What Biome is very dry; receives very little rainfall?

• Tropical Rain Forest

• Desert

• Tundra

What is the greenhouse effect?

• It is a phenomenon where the sun’s rays are absorbed by clouds.

• It is a phenomenon that occurs when heat escapes into space.

• It is when heat is trapped by gases, then sent back to earth’s surface.
