Ecosystem, relatively autonomous dynamic system consisting of a natural community and its physical environment. The concept, first developed in the 1920 and 1930, takes into account the complex interactions between organisms - plants, animals , bacteria, algae , protozoa and fungi between others-that form the community and the flows of energy and materials through it. TERRESTRIAL ECOSYSTEMS
Terrestrial ecosystems are those in which animals and plants live in soil and air. They find everything they need to live. Depending on the abiotic factors of each ecosystem, we can define different kinds of terrestrial habitats: deserts, grasslands and forests. Different plants and animals that inhabit each have different characteristics, as they have adapted to habitats where they live. When changes occur and some species can not adapt, die may become extinct.

About a quarter of the earth's surface is formed by the continents and islands are dry portion of the planet. There is seating inland terrestrial ecosystems, most of which are located in the northern hemisphere. The heights of the land mass rises from sea level to mountain elevations of about 9000 mts. Altitude as Mount Everest in the Himalayas.
Most terrestrial living beings are distributed in the first 6700 meters. Although spores were found bacteria and fungi in atm ósfera to greater heights.
