What is eutrophication?

Eutrophication is the process by which excess nutrients are directly deposited into a water source. Two main sources of these excess nutrients, such as nitrates and phosphates, include agricultural runoff and untreated sewage. The accumulation of these nutrients in a body of water can act as a fertilizer, leading to the proliferation of algae.

Oxidation-Reduction reactions involve the transfer of which subatomic particle?

In oxidation-reduction reactions electrons are transferred between molecules, atoms, or ions. The species that gains electrons is said to be reduced, while the species that loses electrons is said to be oxidized.

What processes occur during the photochemical stage of photosynthesis?

During the photochemical stage of photosynthesis, water is split, molecular oxygen is released, and ADP is phosphorylated.
