Photosynthesis and Chemosynthesis

What is the process of photosynthesis?

• Green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, carbon dioxide, and water.

• Photosynthesis is the process of converting sunlight into heat energy

• Photosynthesis is the process of breaking down glucose to release energy

• Photosynthesis is the process of converting water and carbon dioxide into oxygen and glucose

Define chemosynthesis.

• The process by which plants convert sunlight into energy

• The process by which animals break down organic compounds for energy

• The process by which certain organisms create energy by breaking down inorganic compounds instead of using sunlight.

• The process by which organisms use wind energy to create food

How do photosynthesis and chemosynthesis differ?

• Photosynthesis and chemosynthesis both use sunlight for energy

• Photosynthesis uses sunlight, while chemosynthesis uses chemical energy.

• Photosynthesis and chemosynthesis both produce oxygen as a byproduct

• Photosynthesis and chemosynthesis both occur in animals

Why is photosynthesis important in ecosystems?

• It creates a toxic environment for other organisms

• It produces oxygen and food for other organisms in the ecosystem.

• It has no impact on the ecosystem

• It depletes the oxygen in the ecosystem

• In the Arctic Ocean

What are the similarities between photosynthesis and chemosynthesis?

• Both involve the use of sunlight

• Both occur in animals

• Both produce carbon dioxide as a byproduct

• Both produce energy for organisms

How do temperature and light intensity affect photosynthesis and chemosynthesis?

• By influencing the activity of enzymes and the availability of energy sources.

• By changing the color of the leaves and the size of the plant

• By altering the genetic makeup of the organisms

• By affecting the pH level of the soil and water

Explain the role of chlorophyll in photosynthesis.

• Chlorophyll reflects light energy for photosynthesis.

• Chlorophyll stores light energy for photosynthesis.

• Chlorophyll inhibits light energy for photosynthesis.

• Chlorophyll absorbs light energy for photosynthesis.
