They use sunlight energy, water , and minerals to grow and change
Answer:
A. An increase in nutrients
Explanation:
By definition, eutrophication is excessive richness of nutrients in a lake or body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.
Let's do this by process of elimination: A cannot be the answer because glucose is broken down, not built up or synthesized. B is ruled out for the same reason. D is incorrect because transpiration results in water loss, not energy gain. The only correct answer choice is C respiration, specifically by the process of substrate-level phosphorylation during glycolysis in order to break down glucose into two pyruvate molecules and two net ATP
