How do organisms get the energy they need?

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

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

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

• Plants produce their own energy through photosynthesis, and animals get energy from eating other organisms.

Photosynthesis is the process by which plants transform solar energy into chemical energy. Which of the following correctly describes the roles of each of the materials involved in photosynthesis; after sunlight is captured by chlorophyll? (SC.8. L.18.1)

• Sunlight combines oxygen and water molecules and creates glucose. Remaining atoms form carbon dioxide and water, which are released as waste products.

• Sunlight combines with carbon dioxide and water molecules and creates glucose. Remaining atoms form oxygen which is released as waste product.

• Sunlight combines with glucose and oxygen molecules and creates carbon dioxide. Remaining atoms form oxygen and water, which are released as waste products.

• Sunlight combines water and carbon dioxide molecules and creates glucose. Remaining atoms form carbon dioxide and water, which are released as waste products.
