Terrestrial ecosystems

The terrestrial ecosystems are ecosystems whose biotope is the soil and air. They are highly influenced by the climatic characteristics of each area.

According to the abiotic factors of each ecosystem, different habitats are distinguished, such as deserts, grasslands and forests. The species of plants and animals in each habitat have different characteristics, since they have adapted to living in these conditions. If a species cannot adapt to these conditions, it disappears and may become extinct.

Examples of terrestrial ecosystems are the Mediterranean forest, tundra, savanna, desert, etc.

In terrestrial ecosystems, photosynthetic organisms, producers, live fixed to the ground. The herbivoresinvertebrates and vertebrates, feed on leaves, fruits, roots, seeds, etc., of producers. The carnivores hunt in different ways herbivores, such as wolves are predators, spiders weave their web, bats at night, scavengers like vultures, etc.). Decomposers organisms  recycle dead organic matter and it can be quickly reused by plants.

The flow of energy begins in photosynthetic organisms, which capture sunlight, and through photosynthesis, make organic matter from inorganic matter. Then it goes to herbivores, carnivores, and decomposers.
