1.
How do organisms get the energy they need?
a)
Plants get energy from fertilizers and animals get energy from drinking water.
b)
Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.
c)
Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.
d)
Plants do not require energy because they do not move, and animals get energy by performing exercise.
