Final answer:
Eutrophication is the process of over-enrichment of nutrients in a body of water, leading to the rapid growth of algae. This excessive growth of algae can disrupt the balance of the ecosystem and harm other animal populations.
Step-by-step explanation:
Eutrophication is the process of over-enrichment of nutrients in a body of water, which causes the rapid growth of algae. As the population of algae grows, it can speed up succession by creating an imbalance in the ecosystem. The excessive growth of algae leads to algal blooms, which can block sunlight and reduce oxygen levels in the water. This can lead to the death of organisms that require oxygen and negatively impact other animal populations.
