Terrestrial ecosystems simply refer to the ecosystems found on land. This encompasses a varied array of ecosystems of which there are a few major types: forests, deserts, prairies, mountains and wetlands. These are the fundamental ecosystems that we rely upon for agriculture, raw materials and recreation. Some examples include the Florida Everglades and Yosemite National Park.
Aquatic ecosystems are those that thrive underwater. About 75 percent of the earth is covered by aquatic ecosystems, making it very important to human and animal life. Some aquatic ecosystems include coral reefs, estuaries, freshwater ecosystems, lakes and oceans.
According to the EPA, an agroecosystem is a dynamic association of crops, pastures, livestock, soils, water, flowers and atmosphere. These kinds of ecosystems exist in larger landscapes that include uncultivated land, drainage networks, wildlife and rural communities.
