What does an energy pyramid show?

• the energy that herbivores give to producers

• the amount of energy that moves through carnivores only

• the amount of energy that moves from one trophic level to the next in a food web.

• the amount of lipids a bear consumes

Which sequence shows the transfer of energy within an ecosystem?

• carnivore -----> herbivore------> decomposer-------> omnivore

• omnivore ------> carnivore -------> herbivore -----> primary consumer

• producer ------> decomposer ----->herbivore -----> omnivore

• producer ----> herbivore ------> carnivore -------> decomposer

How do scientists account for the decrease in available energy from one trophic level to the next hgiher trophic level?

• The energy is available to organisms at lower trophic levels.

• The energy of the sun cannot be fully used by producers.

• The energy is stored in energy-dense molecules for decomposers.

• The energy is used by organisms for life functions or is lost as heat.

A carnivore

• is an organism who only eats plants.

• can be a secondary consumer or a tertiary consumer

• is a meat eater.

• Both b and c (meat eater and possibly a secondary or tertiary consumer).

What are the possible descriptions for the grasshopper in this food web?

• secondary consumer, heterotroph, herbivore

• primary consumer, autotroph, omnivore

• primary consumer, heterotroph, herbivore

• primary consumer, autotroph, herbivore
