An organism's or an ecological community's environment is the collection of physical, chemical, and biological variables that affect it and ultimately decide its form and survival.
It consists of natural forces such as chemical and physical ones.
It is a small area of the Earth where interactions between air, water, and land support life.
An ecosystem is made up of the interactions between living things as well as those between them and their surroundings.
Lakes, mountains, oceans, ponds, and other natural areas all have ecosystems.
Lithosphere, hydrosphere, atmosphere, and biosphere are the four main elements of the environment and stand for, respectively, rocks, water, air, and life.
