Animals that eat only meat, such as dolphins, do not get much sugar (carbohydrate) from their diets. Select the statement below that best explains how a dolphin gets the energy it needs from its food.

• The dolphin does not use cellular respiration to get energy from food.

• The dolphin is not very active so it does not need a lot of energy to function.

• The dolphin’s body is able to break down other carbon-based molecules, such as proteins and fats, to use as an energy source for cellular respiration.

• The dolphin gets the energy it needs directly from sunlight.

How do organisms get the energy they need?

• Plants get energy from fertilizers. Animals get energy from water.

• Plants get energy from the soil. Animals get energy directly form sunlight.

• Plants do not need energy because they do not move. Animals get energy from food.

• Plants use energy from sunlight to make sugar molecules. Animals get energy from eating other organisms.
