Q:

What is eutrophication?

A:

Quick Answer

Eutrophication is the process of enriching an ecosystem with nutrients, primarily nitrogen and phosphorous. It can occur naturally in aging lakes. Humans can also introduce these nutrients into an ecosystem, at which point it is called artificial eutrophication.

Full Answer

Fertilizers used in farming can be washed into nearby water bodies, enhancing their nutrient levels. Eutrophication leads to extensive growth and reproduction of algae in the form of algal blooms. These can both benefit and, from time to time, harm the ecosystem. The goal of all eutrophication, natural and artificial, is a balanced and healthy nutrient level in a lake or other ecosystem.

    What is the role of fungi in the ecosystem?

    A:

    Fungi are vital decomposers in the ecosystem, breaking down dead organisms and biological waste, freeing nutrients for use by other organisms and clearing away their remains.

    How do living and nonliving things interact?

    A:

    Living and nonliving things interact with each other by forming an ecosystem, where living things can obtain nutrients and energy from nonliving things through chemical processes. The nonliving things in an environment are known as abiotic factors, while living things are known as biotic factors.
