Photosynthesis, Cellular Respiration, Nitrogen & Carbon Cycles

What do animals do with the carbon dioxide produced in their cells during cellular respiration?

• Store it for later use

• Reuse it during photosynthesis

• Exhale it during the breathing process

• Combine it with water to make sugar

How do organisms get the energy they need?

• Plants get energy from fertilizers & animals get energy by drinking water.

• Plants get energy from glucose from the soil & animals get energy directly from sunlight.

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

• Plants break down glucose produced in photosynthesis; animals get energy from eating other organisms.

Plant cells use photosynthesis to make food.​Plants cells also use cellular respiration to get energy from the food they make.​How is cellular respiration different from photosynthesis?

• Photosynthesis requires oxygen, & cellular respiration requires CO₂

• Photosynthesis produces ATP, & cellular respiration produces sugars

• Photosynthesis produces oxygen & cellular respiration produces also produces oxygen

• Photosynthesis requires energy from food & cellular respiration requires energy from the sun.

Joshua is drawing a diagram of Earth’s nitrogen cycle. What should he write as the role of nitrogen-fixing bacteria?

A

• absorb excess nitrogen compounds

• release nitrogen into the air

• transport nitrogen gas into the soil

• change nitrogen gas into compounds that plants can use.
