Essay On An Ecosystem

An ecosystem is a group of living plants, animals and organisms that interact together in a non-living environment (Ellis). Animals, plants, water and air work together in an structured fashion establishing a balanced system. To have a fully functioning ecosystem, each animal and plant plays a unique role in keeping the ecosystem healthy. There are three categories of living organisms that make up an ecosystem; producers, consumers, and decomposers. The two most imperative roles in the ecosystem are the soil and sun. The sun aids the water cycle and comfortable lifestyles of the animals and the soil stores the nutrients that are required for plants to grow. Ecosystems are a base to all humankind; they provide many goods and services that

The first being soil, which is the most important aspect of an ecosystem that can take hundreds of years to be lost and reformed to hold the maximum amount of nutrients. The second way animals help to rebuild the community is via animal pollination. Animal pollination is required for most all reproductions of plants. Hummingbirds and bees are the most common and powerful pollinators in nature. There are many other animals in an ecosystem that assist in pollinating flowers such as bats, birds, butterflies and flies. The third way a community can try and rebuild it’s self is through seed dispersal that is vital to a surviving ecosystem. We commonly see dandelions growing in grasses and between cracks in pavement like weeds because the seeds are spread via wind. One reason why an ecosystem may need to rebuild itself is because of pest of disease. Pests are known as competitors of humanity who compete for food, timber, and cotton sometimes destroying part of an ecosystem for a long duration of time. The most common pests are insects, rodents, fungi, snails, nematodes and viruses (California, 115). According to an article posted by North Carolina University, pests destroy an estimated 10-25 percent of harvested crops annually. Many ways the community can try and protect the area from pests are with chemical pesticides, which can sometimes have harmful consequences if used over a long duration of
