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). These are, 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. There is life in all three shells. These three shells together support life on Earth, forming another shell - living. Conclusion:

Goals and objectives:
- To form an idea of the factors of the distribution of organisms on Earth;
- Introduce the concepts of “biosphere”, “latitudinal zonation”, “altitudinal zonation”
Slide 3
In the process of evolution, a special shell was formed on Earth - the biosphere (Greek bios “life”).
This term was first introduced in 1875 by the Austrian scientist Eduard Suess.
Biological evolution is a natural process of development of living nature, accompanied by changes in the genetic composition of populations, the formation of adaptations, speciation and extinction of species.
Slide 4
In the 20s of the twentieth century, the outstanding Russian scientist academician Vladimir Ivanovich Vernadsky (1853-1945) developed the “Doctrine of the Biosphere”
Slide 5
What is the “biosphere”? To what boundaries (upper and lower) does it extend? What
represented by organisms? Fill out the chart
- Biosphere
- Bacteria
- Biosphere
- Bacteria
- Mushrooms
- Plants
- Animals
Slide 6
The boundaries of the Earth's biosphere are drawn along the boundaries of the distribution of living organisms, which means...
That its upper boundary passes at the height of the ozone layer at an altitude of 20-25 km...
...and the lower boundary passes at the depth where organisms cease to be found.
Slide 7
What conditions influence the distribution of organisms on Earth? Fill out the table
Slide 8
Read paragraphs 3, 4 Define the phenomena “Latitudinal zoning”, “altitude
zoning” using the formula: definition = keyword + essential features
Determine from Fig. 93 Natural areas of the Earth
- Latitudinal zoning is the sequential arrangement of natural zones from the poles to the equator, associated with changes in the ratio of heat and moisture.
- Altitudinal zonation - sequential arrangement of natural zones in the mountains

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 and their uneven distribution on the 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 the deep parts of the earth's crust. The richest flora and fauna of the humid 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 large worms and crustaceans that are not found in other places.
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.
Rice. 7. Anglerfish ()
