The organism that is incapable of producing food for their needs and depends on other organisms are called heterotrophs while the food-producing organisms are called autotrophs.
Autotrophs supply oxygen for respiration to the heterotrophs.
The dependency of heterotrophs can be explained as:
- The autotrophs are capable of producing oxygen from the sunlight, carbon dioxide and water by the process of photosynthesis.
- The heterotrophs are incapable of utilizing the atmospheric carbon dioxide and the water to yield oxygen needed for respiration.
Therefore, option A. the autotrophs provide oxygen to the heterotrophs for respiration.
