The main environment of the life of living organisms and their characteristics briefly

Life originated on Earth approximately 3.7 billion years ago, according to another source about 4.1 billion years ago. Development continues to this day. For all assumptions, and in the future life will continue, adapting to the environment, and the presence or absence of a person will not be able to interrupt it.

Australia scientists have discovered signs of life on land, and they are 3.5 billion years. Their finds gave confirmation that life was formed in fresh reservoirs, and not in salty sources. Scientists drew attention to these facts and are looking for confirmation by them and on other continents.

The main types of life

The main environment of life includes:

  • water;
  • ground-air;
  • soil;
  • organism (parasites and symbionts).
  • Each of the environment has its own characteristics and contains various organisms that live, propagate and evolve.

    Ground-air environment

    This environment represents the whole variety of plant and animal life on Earth. The development of organic life on land made it possible to arise. Then the development of plants, forests, steppes, tundra and various animals adapting to different habitats. As a result of the further evolution of the organic world, life spread to all the upper shells of the Earth hydrosphere, lithosphere, atmosphere. All living things developed and adapted to sharp temperature fluctuations and various habitats. There were warmblooded and coldblooded representatives of the animal fauna, a variety of birds and insects. In the ground-air environment, the plants adapted to various growing conditions. Some love light warm areas, others grow in the shade and humidity, and others survive at low temperatures. The variety of this environment is represented by a variety of life in it.

    Water environment

    In parallel to the development of the ground-air environment, development and the water world was also underway.

    The aquatic environment is represented by all reservoirs that are on our planet, from oceans and seas, ending with lakes and streams. 95% of the surface of the Earth belongs to the aquatic environment.

    Various gigantic inhabitants of the aquatic environment changed and adapted under the waves of evolution, adapted to the habitat and took a form that the most increasing survival of populations. The sizes decreased, the areas of the spread of different types of their coexistence shared. The diversity of life in water is surprising and delighted. The temperature in the aquatic environment is not subject to such sharp fluctuations as in the ground-air environment and even in the coldest reservoirs does not decrease below +4 degrees Celsius. Not only fish and animals live in water, also water abounds with various algae. Only at great depths are they absent, where eternal night reigns, there is a completely different development of organisms.

    The soil environment

    The top of the earth belongs to the soil. Mixing various soil breeds with rocks, the remains of living organisms, forms fertile soil. There is no light in this environment, they live in it, or rather grow: seeds and disputes of plants, roots of trees, shrubs, herbs. It also has small algae. Earth is a house for bacteria, animals and mushrooms. These are its main inhabitants.

    Body as a habitat

    There is not a single person on Earth, the type of animals or plants in which any organism or parasite did not sett. The parasites of plants include the wellknown povilik. The body grows from small spores, which lives through the absorption of the nutrient forces of the host plant.

    Parasites (from the Greek “parasite”) this is an organism living at the expense of its owner. Many organisms parasitize in the bodies of people and animals. They are divided into temporary ones that live on the owner a certain cycle, and permanent, which parasitize the cycle behind the host. This often leads to the death of the owner-carrier. All living things are subject to parasites, starting from bacteria, and completes this list of higher plants and animals. The parasites include viruses.

    Symbiosis (joint life) can also be added to organisms.

    The symbiosis of plants and animals does not inhibit the owner, but acts as a partner in life. Symbiotic relations allow you to survive certain species of plants and animals. Symbiosis a gap between the union and the merger of organisms.
