What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy through different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to primary consumers and then to higher trophic levels.

Front

What percentage of energy is typically passed from producers to primary consumers?

Back

Approximately 10% of energy is passed from producers to primary consumers.

Front

Why do tertiary consumers have less available energy than primary consumers?

Back

Energy is lost as heat at each trophic level.

Front

What two body systems interact to produce a sneeze?

Back

The nervous system and the respiratory system interact to produce a sneeze.

Front

What role do hormones play in the body?

Back

Hormones are chemical messengers released into the bloodstream that help regulate various functions in the body, including growth, metabolism, and mood.

Front

Which body systems are involved in hormone release?

Back

The endocrine system releases hormones, and the circulatory system transports them to target locations.

Front

What is a structural adaptation?

Back

A structural adaptation is a physical feature of an organism that enhances its ability to survive and reproduce in its environment.

Front

What factor most likely leads to the development of structural adaptations in a population?

Back

Consistent environmental pressures over time lead to the development of structural adaptations.

Front

What is the role of primary consumers in an ecosystem?

Back

Primary consumers are organisms that eat producers (plants) to obtain energy.

Front

What happens to energy as it moves up the trophic levels in an energy pyramid?

Back

Energy decreases as it moves up the trophic levels due to energy loss as heat and metabolic processes.
