An ecosystem is a community of interacting organisms and their environment. Living things interact with each other and also with non-living things like soil, water and air.
There are two types of ecosystems:
• A natural ecosystem is a naturally produced biological environment found in nature.
It includes deserts, forests, grasslands, lakes, mountains, ponds, rivers, oceans, etc.
• An artificial ecosystem is an artificial environment which is created and maintained by man. It includes aquariums, crop fields, gardens, parks, zoos etc.
