WHAT'S AN ECOSYSTEM?

We can find life in all types of climates and landscapes. All of these places and the organisms that live in them form a variety of ecosystems.

Ecosystems:
An ecosystem is made up of two parts, the biotope and the biocoenosis.
  • The biotope, or phisical environment includes all of the non-living things in an ecosystem (geographical relief, soil, light and temperature).
  • The biocoenosis includes all the living things in an ecosystem (plants, animals and other organisms).
There can be many different organisms in an ecosystem.
  • A population is a group of organisms that live together and belong to the same species.
  • A community is a collection of different populations that live together in one place.
In an ecosystem, we can classify the relationships betweeen individual organisms.
  • Intraspecific relationships exist between individual members of the same species.
  • Interspecific relationships exist between individual members of different species.
