17 E. Energy pyramid

18 What is the source of energy for producers?
A. the sun, because producers need light to make food. B. the earth, because the soil provides warmth and nutrients. C. wind, because producers need wind to scatter their seeds. D. fresh water, because producers need water to make food

19 A. the sun, because producers need light to make food.

20 What kind of animal comes last in every food chain?
A. carnivore B. decomposer C. herbivore D. producer

21 B. decomposer

A. bacteria that live on some plant roots fix nitrogen gas B. plants release nitrogen compounds during transpiration. C. Bacteria break down animal wastes and dead organisms. D. lightning produces nitrogen compounds that dissolve in rain.

25 B. plants release nitrogen compounds during transpiration.

26 Which substance enables a plant to use the sun’s energy to make food?
A. chlorophyll B. oxygen C. sugar D. water

27 A. chlorophyll

28 Which is a product of photosynthesis?
