Why is photosynthesis important for life on Earth?

• It produces carbon dioxide, which animals need to breathe.

• It is the process by which plants produce food.

• It generates oxygen, which is essential for aerobic respiration.

• It consumes large amounts of harmful greenhouse gases.

How do heterotrophs obtain energy?

• By producing their own food through chemosynthesis

• By consuming autotrophs or other heterotrophs

• By absorbing sunlight and converting it into chemical energy

• By breaking down minerals in the soil

What role does chlorophyll play in photosynthesis?

• It absorbs water to provide the necessary hydrogen atoms.

• It captures sunlight and converts it into chemical energy.

• It breaks down glucose molecules to release energy.

• It facilitates the conversion of oxygen into carbon dioxide.
