What does the law of conservation of energy state?
It is important to use as little energy as possible.
Organisms save the energy that they create.
Organisms change energy into mass.
Energy cannot be created or destroyed.
During cellular respiration, cells break down food to release energy. During photosynthesis, cells produce food in the form of glucose. What is one difference between these two processes?
Cellular respiration uses oxygen and photosynthesis produces oxygen.
Cellular respiration uses carbon dioxide and photosynthesis does not.
Cellular respiration produces oxygen and photosynthesis does not.
Photosynthesis produces twice as much glucose than cellular respiration does.
In the carbon cycle, how do living things store most of their energy?
water
organic molecules
light energy
heat energy
What do plants do with the oxygen produced in their cells during photosynthesis?
reuse it during photosynthesis
combine it with water to make sugar
exhale it
store it for later use
