Question
Carbon from the atmosphere enters food chains through the actions ofMultiple choice question.methanogens.decomposers.photosynthetic autotrophs.fossil fuel combustion.
Solution
The correct answer is "photosynthetic autotrophs."
Here's why:
-
Photosynthetic autotrophs, such as plants and algae, are organisms that can produce their own food using light, water, carbon dioxide, or other chemicals.
-
During the process of photosynthesis, these organisms take in carbon dioxide from the atmosphere.
-
The carbon dioxide is then used, along with sunlight and water, to produce glucose (a type of sugar) and oxygen.
-
The glucose is used by the plant for energy and growth, effectively moving the carbon from the atmosphere into the plant, and from there, it can enter food chains when the plants are eaten by animals.
So, carbon from the atmosphere enters food chains through the actions of photosynthetic autotrophs.
