Biology Quiz on Organisms and Cellular Processes

Biologists measure the length of a tagged sea turtle. They learn that the turtle is 2.3 cm longer than the last time it was measured. Where did the sea turtle get the nutrients it needed to grow?

• from the jellyfish it ate

• from sunlight it absorbed

• from the oxygen it breathed

• from nutrients it absorbed from the water

Living things can be grouped depending on how they get food. Some organisms get food from eating other organisms. Other organisms can make their own food. In which group do organisms that can make their own food belong?

• consumers

• decomposers

• predators

• producers

Sawgrass takes in light energy during photosynthesis. What happens to most of this energy?

• It is stored as chemical energy.

• It disappears as it is used up by the plant.

• It is transferred to organisms that eat the grass.

• It is used to help the sawgrass grow and reproduce.
