Throughout this course we have talked about the Earth as a planet and also that it behaves with a system that integrates several layers:
- Geosphere.
- Atmosphere.
- Hydrosphere.
- Ecosphere, which is the topic we are going to deal with now. It is the part of our planet in which living beings live.
Ecosphere
The ecosphere is the area of the Earth in which there are adequate conditions for the existence of life. The ecosphere is the global system of the Earth, made up of all the organisms that make up the biosphere and is characterized by the relationships established between living beings, matter and energy. That is, the ecosphere can also be considered the set of ecosystems that we can find on Earth.
On Earth, living things can live in the atmosphere, the hydrosphere, and the Earth's crust:
- Atmosphere. The atmosphere is the outermost layer of the Earth made up of the gases that make up the air.
- Hydrosphere. The hydrosphere is the layer formed bywater, bothsaltyandfresh, ina liquidandsolid, such asglaciers.
- Eart crust. The crust is the solid layer formed by rocks , whose superficial part gives rise to the ground and the seabed.
Biosphere
The biosphere is the system formed by the set of living beings on Earth, which interact with each other and with the atmosphere, the hydrosphere and the lithosphere, living in the air , in the water or on the ground.
Ecosystem
The ecosystem is the set formed by living beings (biocenosis), the physical environment in which they live (biotope), and the relationships established between them.
- The biotope comprises the abiotic factors, the non-living components, such as location and physical conditions.
- The biocenosis or community is formed by the living components, the organisms that live in the ecosystem. They are biotic factors.
Biotope and biocenosis are closely related, since there are very complex relationships as a result of the adaptation of living beings to the environment.
