Question

5 multiple choice 1 point
what process absorbs carbon dioxide from the atmosphere?
combustion of fossil fuels
cellular respiration by plants and animals
decomposition by bacteria
photosynthesis by autotrophs

Explanation:

• Combustion of fossil fuels releases CO₂ into the atmosphere, not absorbs it.
• Cellular respiration by plants and animals produces CO₂ as a waste product, releasing it.
• Decomposition by bacteria breaks down organic matter and releases CO₂.
• Photosynthesis by autotrophs (like plants) uses CO₂ from the atmosphere, along with water and sunlight, to produce glucose and oxygen, absorbing CO₂ in the process.

Answer:

D. photosynthesis by autotrophs
