Think of your home and all of the things in it. You likely have furniture, books, food in your refrigerator, family, and maybe even pets. Your home consists of a variety of living and non-living things.
Like your home, an ecosystem is any community of living and non-living things that work together. The living things are biotic features, and the non-living things are abiotic features. While ecosystems do have boundaries, they are not always clear, and it may be difficult to see where one ecosystem ends and another begins.
