All living things need energy to stay alive, but they don't all get energy in the same way. Fungi, like mushrooms, get energy from dead plants and animals, while most plants are able to convert energy inside of their cells. The energy that plants convert starts as sunlight and is converted through a chemical process called photosynthesis. For photosynthesis to occur, a plant needs water and carbon dioxide, as well as that initial sunlight. Through photosynthesis, the sun's energy is converted into glucose, a simple sugar that cells use as an energy source. Humans are not producers, like plants, or decomposers, like fungi. Humans and other animals are consumers. Our energy comes from the food that we eat. Digestion breaks down that food into substances, including an important simple sugar that our cells can use for energy: glucose. Based on the passage, both plants and humans (what)

a. eat food for energy.

b. use glucose as a source of energy.

c. are producers.

d. break decomposers into sugar.
