Soil, aquatic, atmospheric, and biodiversity combine to form the Earth's ecosystem.
The ecosystem extends to an altitude of about 26 km above the earth's surface.
About 9 km above sea level. Most of the ecosystem lies at depth.
It contains many species of fish, sharks, whales, octopuses and marine flora.
The ecosystem extends to a depth of several meters below the surface.
In nature, biological elements such as animals or plants and micro-organisms combine intricately with inanimate elements such as animals, gases, soil, light, etc. to form a self-governing system called an ecosystem.
The two main types of ecosystems are as follows.
$(1)$ Terrestrial ecosystem $(2)$ Aquatic ecosystem.
The terrestrial ecosystem includes grasslands, semi-arid regions, deserts, islands, etc.
Aquatic ecosystems include lakes, ponds, wetlands, rivers and river mouths, seas, etc.
Energy flow in the ecosystem:
Every ecosystem has many interrelated structures.
Ecosystems are regulated by the water cycle, the carbon cycle, the oxygen cycle, the nitrogen cycle, the energy cycle, and so on.
However, the biological and inorganic characteristics of each habitat are different.
The functions of ecosystems are somehow related to the growth and regeneration of plant and animal species.
These mutually integrated processes can be described as different cycles.
All these processes are based on the energy received from sunlight.
During photosynthesis, plants absorb carbon dioxide from the air and release oxygen into the air.
Animals use oxygen in respiration.
The water cycle depends on aquatic life.
Which is indispensable for plants as well as animals.
The energy cycle re-mixes soil nutrients into the soil.
On the basis of which the plant grows.
Every organism is fully involved with the proper functioning of these organisms.
