Unit 4 Test Review - Energy Transfer (Morris)

Front

What is the flow of energy in an ecosystem?

Back

Energy moves in one direction from the Sun to the producers and then to the consumers.

Front

What is an example of a relationship between a consumer and a producer?

Back

A deer eating grass.

Front

What are the four levels of an energy pyramid?

Back

Producers (level 1), primary consumers (level 2), secondary consumers (level 3), and tertiary consumers (level 4).

Front

What is an autotrophic organism?

Back

An organism that produces its own food, typically through photosynthesis, like green plants.

Front

What is the correct sequence of energy flow in an ecosystem?

Back

Sun → green plants → herbivores → carnivores.

Front

What role do producers play in an ecosystem?

Back

Producers convert solar energy into chemical energy through photosynthesis.

Front

What is a consumer in an ecosystem?

Back

An organism that obtains energy by consuming other organisms.

Front

What is the difference between herbivores and carnivores?

Back

Herbivores eat plants, while carnivores eat other animals.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil.

Front

How does energy decrease as it moves up the energy pyramid?

Back

Energy decreases due to energy loss as heat and through metabolic processes.
