The image is an Energy Pyramid. Which statement correctly describes the flow of energy in this energy pyramid?

• Most of the energy is transferred from the producers to the primary consumers.

• Most of the energy is transferred from the secondary consumer to the tertiary consumer.

• The least amount of energy is transferred from the producers to the primary consumers.

• The least amount of energy is transferred from the secondary consumer to the tertiary consumer.

Why is the flow of energy within a food web complex?

• Most organisms are consumed by more than one species of organisms.

• The usable energy decreases with each subsequent lower feeding level.

• The greatest amount of energy lies at the higher-level consumer.

• Most organisms eat only one type of food within their own ecosystem

The diagram is of a food web. The arrow between the ferns and the insects represents the

• fact that the ferns and the insects required the same nutrients.

• energy in the ferns that is being transferred to the insects.

• the movement of the ferns into the insects ecosystem.

• nutrients in the insects flowing to the ferns

A disease kills an organism that is a secondary consumer in a food web, and the organism decays. What is the next thing that happens to the energy in the organism's body?

• It is transferred to producers.

• It is transferred to decomposers.

• It is transferred to other secondary consumers.

• It is transferred to tertiary consumers.

The image shows a food web in the mountains of Georgia. Which best describes 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 multiple consumers in the ecosystem.

Which best describes a food web?

• a less complex food chain that shows how producers gain their energy from the Sun

• a more complex food chain that shows how organisms are able to digest their nutrients

• a combination of food chains that show how organisms interact to get their required energy and matter

• a single food chain that shows how organisms interact to get their required energy and matter
