Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of levels that a food chain can reach. Why is there a limit to the number of levels that a food chain can reach?

• Sunlight is limited in all ecosystems.

• Producers can only eat what is available.

• Carnivores are too big to be eaten.

• Energy is lost when you move up a trophic level.

Yellowfin tuna, or Thunnus albacores, are large sport fish that are found in tropical and subtropical waters around the world. They typically school under objects such as boats or patches of driftwood for protection from predators. Schooling under these structures also provides yellowfin tuna with easy access to a food source such as smaller herbivorous fish that may be foraging for food around the structures. Which trophic level does yellowfin tuna fill in a food chain?

• producer

• primary consumer

• secondary consumer

• tertiary consumer

What would happen to the organisms in the food web below if the number of phytoplankton and vegetation decreased?

• Only the small fish would be affected.

• Only the osprey would be affected.

• The small fish and wading birds would be affected.

• The entire food web would be affected.

Mice eat seeds, small fruits and berries, beetles, caterpillars, grasshoppers, leafhoppers, and an underground fungus. What happens if all the grasshoppers die?

• The mice die because of a food source being removed.

• The mice survive due to biodiversity.

• The beetles and caterpillars increase in population.

• The beetles and caterpillars decrease in population.

Which describes the greatest benefit of species diversity?

• It tends to lead to more stable, resilient ecosystems.

• It ensures that consumers have a single food source.

• It reduces competition among species for resources.

• The species no longer have to adapt to survive.

• .

Where does the energy from an ecosystem come from?

• Trees
• Sun
• Plants
• Water
