What are the differences encountered in the photosynthetic-respiratory pathway of the carbon cycle, as it exists on land and in the ocean?
In a marine environment, the role of plants is performed by _______(phytoplankton, zooplankton, microorganisms) and an additional flux of carbon into the oceans is through _______(aeration, diffusion, deposition).
Answer:
phytoplankton; diffusion
Explanation:
"Phytoplankton" takes the role of the plant in the marine environment because it consists of tiny plants that contain chlorophyll–just like the terrestrial plants. This provides food to many aquatic animals in the ocean.
When it comes to carbon cycle, carbon dioxide from the atmosphere is being diffused into the ocean by dissolving it. The carbon in the ocean turns into an organic matter through the process of photosynthesis. The ocean is said to have more carbon compared to the atmosphere because many marine animals use it for survival.

Explanation:
Why is it dangerous to have too much carbon dioxide in the atmosphere
Answer:
too much CO2 is toxic for humans to inhale. we rely on plants to absorb CO2 and produce O2. If they was a sudden extinction of all plants on earth, this would lead to a rise of CO2 which would reduce O2 air quality. (not good at all)
