Aphids are insects that feed on the sap of plants. Aphids can destroy a healthy plant by eating all of its sap or by introducing disease to the plant.

Which statement BEST describes the type of relationship that exists between aphids and the plant?

• Mutualism

• Predator-prey

• Parasitism

• Commensalism

The picture shows a prairie environment.

How can the vulture's role best be described?

• the vulture is a parasite who gets nutrients by feeding other organisms

• the vulture is a producer that returns vital nutrients to the ground

• the vulture is a scavenger who helps break down decomposing material

• the vulture is a predator that eats other organisms

A diagram of a food web is shown below.

How would a reduction in the snail population affect this ecosystem?

• it would cause decreased competition between spirders and owls

• it would cause increased competition between grasshoppers and beetles

• it would cause increased competition between wood mice and shrews

• it would cause decreased competition between spiders and wood mice

what happens to light energy from the sun when it reaches the surface of the Earth?

• The light energy is multiplied when it reaches the plants on Earth

• the light energy is transformed to chemical energy by photosynthesis

• the light energy is destroyed when plants are eaten by herbivores

• the light energy is converted to potential energy by cellular respiration

The picture shows a food web in the mountains of Georgia.

Which BEST decsribes the organisms that would recycle decaying matter back into the mountain ecosystem.

• The mushrooms because they are decomposers and break down matter to return to the ecosystem

• The Sun because it provides all the energy required for the organisms to return matter to the ecosystem

• The deer because they are consumers and break down the matter from producers to return to the ecosystem

• The berries and flowers because they are producers and are broken down for the multiple consimers in the ecosystem
