Environmental science is a class when you learn about earth's atmosphere, earth's core, habitats, food chains, food webs, and natural resources. Its all about the environment and the earth. This allows us to learn how the environment works, and how the earth works. Without any of these studies we wouldn't know how the earth and environment work and we would be confused

A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals. A simple food chain could start with grass, which is eaten by rabbits.

A nonrenewable resource is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years.

A renewable resource is a resource which can be used repeatedly because it is replaced naturally. Examples are: oxygen, fresh water, solar energy, timber, and biomass. Renewable resources may include goods or commodities such as wood, paper and leather, because their sources are renewable.
