Photosynthesis and Respiration

How do organisms get the energy they need?

• Plants get energy from fertilizers and animals get energy from drinking water.

• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.

• Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.

• Plants do not require energy because they do not move, and animals get energy by performing exercise.
