Terrestrial environment is an environment consisting of landforms only. It is referred to the earth’s land area which includes both manmade and natural surface, the sub-surface characters, its interfaces and interactions with the earth’s atmosphere and oceans. These environments are inhabited by terrestrial entities. These community of entities and their environment existing on landmasses of continents and islands are different from aquatic ecosystems in a way that they have lower availability of water. These environments are characterized by a high fluctuation in the temperature on both a seasonal basis and diurnal occurring in aquatic ecosystems in similar climatic conditions. A few primary terrestrial ecosystems existing are tundra, tropical rain forest, deserts, grasslands.
