A Correct answer
Explanation

Photosynthesis removes carbon from the atmosphere, and respiration returns it. These two processes are the primary drivers of the short-term biological carbon cycle.

Multiple choice
  1. glucose

  2. breaking down other organisms

  3. light

  4. carbon dioxide

D Correct answer
Explanation

Photoautotrophs use light as an energy source and carbon dioxide as their sole or principal carbon source. They fix inorganic carbon into organic molecules.

Multiple choice
  1. Photography

  2. Photosynthesis

  3. Reproduction

  4. Adaptation

B Correct answer
Explanation

Photosynthesis is the biological process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Multiple choice
  1. carbon dioxide

  2. plasma

  3. oxygen

C Correct answer
Explanation

Photosynthesis is the process by which plants convert light energy into chemical energy, releasing oxygen as a byproduct.

Multiple choice
  1. take in carbon dioxide

  2. take in oxygen

  3. take in animals

  4. release carbon dioxide

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Plants require carbon dioxide as a reactant for photosynthesis to produce glucose.

Multiple choice
  1. Photosythesis

  2. Eutrophication

  3. Respiration

  4. Transipiration

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photosynthesis is the process by which plants synthesize glucose using sunlight, carbon dioxide, and water. It occurs primarily in chloroplasts of leaf cells.

Multiple choice
  1. True

  2. False

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plants primarily absorb carbon dioxide for photosynthesis, not oxygen. While they do exchange gases, the primary intake for food production is carbon dioxide.
