Phytoplanktons are the main producers of the aquatic system. these microscopic plants use the carbon dioxide in the ocean to produce food. this is an example of a interaction. a) hydrosphere and atmosphere b) biopsphere and chronosphere c) geosphere and atmosphere d) hydrosphere and biosphere e) biosphere and geosphere

The correct answer is D. Hydrosphere and biosphere

Explanation:

The hydrosphere refers to all water and all body waters found on Earth including lakes, rivers, oceans, streams, etc. On the other hand, the biosphere refers to all forms of life such as animals, plants, bacteria, among others. In the case of Phytoplanktons that use the carbon dioxide from the ocean to produce food, there is a hydrosphere and biosphere interaction as the plankton which is part of the biosphere uses the substances from the hydrosphere to produce food. Thus, this situation is an example of a hydrosphere and biosphere interaction.
