Is my response to this good is there anything I can change or add to make it better? You now know what an ecosystem is—and how varied ecosystems can be. Pick an ecosystem near you—find one that it as large or small as you wish. All areas—urban, suburban, and rural—have many ecosystems to choose from. Write a description of the ecosystem, including biotic and abiotic factors, in NO MORE THAN FOUR SENTENCES.An ecosystem close to me is a river. Abiotic factors: High water quality and the water is very clear. The average water temperature is 55F, and the water gets a lot of sunlight. Biotic factors: There are many different types of fish, such as bull trout and salmon. Many different kinds of frogs live in and along the edges of the river, and various kinds of plants and algae.
