What is ecosystem and why do we need it

Explanation:

Most human habitats are in the same sorts of places as animal habitats, like forests and grasslands, but humans and animals live in very different kinds of shelters.Every living thing, including man, is involved in these complex networks of interdependent relationships, which are called ecosystems. Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food.A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. Decomposers break down dead plants and animals, returning vital nutrients to the soil.In order to survive, ecosystems need five basic components: energy, mineral nutrients, water, oxygen, and living organisms. Most of the energy of an ecosystem comes from the sun.Moreover, the major parts of an ecosystem are: water, water temperature, plants, animals, air, light and soil.
