Distribution of living organisms on Earth. Living organisms on our planet are very diverse. This includes humans, animals, plants, fungi, and bacteria. Some live in the lithosphere (earth). This is, for example, earthworms and moles. If we look at a lump of soil under a strong magnifying glass, we will see bacteria and microorganisms. We most often see the eagle and other birds soaring in the sky. The sky is their element. They live in the atmosphere permanently, and are found temporarily in other shells (lithosphere and hydrosphere). In addition to birds, other living organisms also live in the atmosphere. Scientists have calculated that 1 cubic meter of air contains several thousand bacteria and microorganisms. Life exists in all three shells. These three shells together support life on Earth, forming another shell - living. Conclusion:

This lesson will introduce you to the topic "Distribution of Organisms." It is the first in the “Biosphere” section. The lesson will help you form an idea of ​​organisms as components, their uneven distribution across earth's surface. Consider all the diversity that exists on our planet and discuss the relationship between them.

The distribution of living organisms is determined by climatic conditions, soil structure and other factors. On the other hand, organisms themselves can change their habitat and influence the climate. The highest concentration of living organisms is characteristic of the land surface, in the shallow part of the ocean.

Living organisms closely interact with each other and with other shells of the Earth and thus exist. Living organisms live even in the stratosphere and in deep parts earth's crust. The richest plant and animal world wet equatorial forests. These forests contain an abundance of heat, moisture and food.

Rice. 2. Equatorial rainforests ()

Plants are capable of creating organic substances from inorganic ones. Plants are eaten by certain types of animals (herbivores), which in turn are eaten by predators.

Rice. 3. Predatory animals of the Arctic ()

In the cold and hot dry areas of the planet there are much fewer living organisms than in forests.

Rice. 4. Sahara Desert in the photo ()

Conditions for the existence of living organisms in the ocean:

1. Amount of sunlight

2. Depth

3. Properties of water (salinity, composition, amount of nutrients)

4. Currents

5. Availability of food

6. Temperature

Algae predominate among plants in the ocean.

Rice. 5. Algae ()

The largest inhabitants of the ocean swim freely (seals, penguins, whales, walruses, dolphins, etc.). Crustaceans, mollusks, and worms live at the bottom of oceans and seas. Small organisms that are carried by the water column are called plankton. Plankton is the main food for fish and mammals, so waters rich in plankton are also rich in fish. At significant depths there are much fewer living organisms.

Many living organisms live near hydrothermal vents. There are many bacteria here, which, like plants, produce organic matter. Also near these sources live big worms, crustaceans that are not found elsewhere.

Lianas are very common plants. They are very flexible and can reach significant lengths.

These fish live in cool waters at considerable depths, burying themselves in the sand.

Collection of parts earth's shells(lithosphere, hydrosphere and atmosphere) form the biosphere, which is populated by living organisms participating in life processes on Earth.

The biosphere is one of the shells of the Earth, which is inhabited by a variety of living organisms. The biosphere has developed in the process of evolution; it is under the influence of living organisms and is transformed by them.

The biosphere penetrates the lithosphere, hydrosphere, and atmosphere. In total, there are approximately 3,000,000 species of animals, plants, bacteria, and fungi in the biosphere. Organisms included in the biosphere exhibit an extraordinary ability to spread throughout the planet and reproduce. There are several million species of organisms on Earth. Energy flows are distributed on earth in accordance with the state of the biosphere. Plants release oxygen (11.5 ∙ 107 tons per year) and absorb CO2 (1.7 ∙ 108 tons), if plants disappeared, life on earth would die due to the accumulation of CO2 in the atmosphere.

Animals - ecosystems

An ecosystem is a biosystem that consists of living organisms, their habitat, and connections in the system. Animal species make up natural communities. An ecosystem is located on a certain territory, it is composed of certain species, it is distinguished by a certain structure and bioproductivity.

The interaction of producers and consumers guarantees the prosperous existence of any ecosystem. Animals cannot live without plant nutrients; predators cannot exist without herbivores. Many species consume other species and themselves become a breeding ground for other members of the ecological community. Birds of prey eat hares, mice, frogs, snakes, and lizards. In turn, snakes eat frogs, mice, and small birds. The bear predator simultaneously feeds on honey, carrion and plants. The fox, as a predator, catches hares, but can also eat fruits. Food chains are very complex; they can easily break down if even one link in the chain is broken.

The richer the biocenosis, the stronger the ecosystem. If the hares disappear from the food chain that consists of plants, foxes and hares, then the foxes will be able to survive because they will feed on birds and mice.

Plants - ecosystems

Vegetation primarily determines any ecosystem. Rainforests, steppes, semi-deserts and deserts are characterized by plant communities. In the forests of the tropics special trees, grass, undergrowth, which are inhabited by fungi, microorganisms, and animals.

A forest ecosystem is characterized by a combination of plants adapted to live with each other. The upper tier is occupied by tall light-loving trees, below are small trees that are less light-loving, the undergrowth is formed by shrubs, and the next tier is formed by grasses. Another layer consists of mosses.

The layering of a forest ecosystem is the most important factor that allows the existence of plants with different needs for sunlight.

Microorganisms

Microorganisms are an important link in the cycle of various substances (nitrogen, carbon, phosphorus) in nature. They decompose the remains of plants and animals, helping to cleanse the soil and water. The balance of microorganisms in the human body determines his well-being and health.

The ability of any ecosystem to maintain its connections, structure, and functions determines its stability in any adverse conditions.
