Answer:
The correct answer will be option-B.
Explanation:
Photosynthesis process takes place in two phases: light-dependent reaction and light-independent reaction.
The light-independent reaction takes place in the fluid-filled space called stroma of a chloroplast and is involved in the formation of glucose molecules. The light-independent reactions take place in cycles and are known as the Calvin cycle.
Calvin cycle proceeds in three phases: carboxylation or carbon fixation, reduction and regeneration. During reduction, the ATP and NADPH provides energy and hydrogen atom to the 3-PGA which gets converted to glyceraldehyde-3-phosphate (G3P).
Thus, Option-C is the correct answer.
Degradation means the wearing down of or slow lowering to a weaker position.
Dead zones are created by hypoxia and the bacterial decay of dead phytoplankton.
<h3>What are the effects of excess phytoplankton population?</h3>
The Chesapeake Bay, like many other bodies of water, is overrun with nutrients, which results in a type of pollution called eutrophication. Every spring, sewage treatment facilities, farms, and lawns release large amounts of nitrogen and phosphorus into the Bay. These nutrients fuel the growth of algae as the water warms up in the summer, resulting in blooms that deplete the water's oxygen content and create sizable "dead zones" where fish, crabs, and other aquatic life find it challenging to survive. During these times, some of the mud's surface layers and portions closer to the bottom may become anoxic, meaning there is no oxygen present at all.

Generalist species are adapt to live in a wider range of environment conditions. Specialist species are adapt to live in a narrow range of environment conditions. Thus, specialists are in a greater danger if some of the conditions in the environment change. For example, species A and B live in a river with an average temperature of 17°C. Species A is the generalist species and it can survive water temperature of 5-35°C. Species B is the specialist species and can survive water temperature of 15-20°C. If the temperature of the river decrease to 10°C, specialist species B will not survive but generalist species a will survive.
