Multiple Choice

In what way do animals indirectly rely on photosynthesis for their energy needs?

Animals use photosynthesis to produce glucose in their cells.

Animals consume plants or other animals that have consumed plants, which derive energy from photosynthesis.

Animals rely on photosynthesis to produce oxygen, which they use for respiration.

Animals directly convert sunlight into energy through their skin.

Verified step by step guidance

Understand the process of photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose. This process also produces oxygen as a byproduct.

Recognize the role of plants in the ecosystem: Plants are primary producers, meaning they are at the base of the food chain. They convert sunlight into energy, which is stored in the form of glucose and other carbohydrates.

Identify how animals obtain energy: Animals are consumers in the food chain. They cannot perform photosynthesis themselves, so they rely on consuming plants or other animals to obtain energy. When animals eat plants, they are indirectly accessing the energy stored in the plant's glucose.

Consider the role of oxygen in animal respiration: Photosynthesis produces oxygen, which is essential for animal respiration. Animals breathe in oxygen to help convert glucose into usable energy through cellular respiration.

Clarify the misconception about direct energy conversion: Animals do not directly convert sunlight into energy through their skin. Instead, they rely on the energy conversion processes performed by plants during photosynthesis.
