This document provides an overview of terrestrial ecosystems. It defines an ecosystem as a community of living things that interact with each other and their environment. Examples of ecosystems include deserts, tundra, grasslands, rainforests and different types of forests. Desert ecosystems are described as having an arid climate and being located in parts of Africa, Asia, Australia, the United States and South America, and containing plants like cacti and animals like coyotes. The document also defines producers, consumers, decomposers, populations, communities and habitats within ecosystems.
