SUMMARY ECOSYSTEMS

Pages 46, 47

    An ecosystem is a place where living and non living things interact each other. It can be different sizes: microscopic, medium size, huge…

It is formed by:

- Biotope: The non living things that are there (sand, rocks, soil, water, temperature, sun…)

- Biocenosis: The living things in the area (animals, plants, microorganisms, humans)

         The afore mentioned elements interact each other in a perfect balance and any change introduced in an ecosystem has big consequences on it.

         Living things group each other in :

- Population: when living things same specie live together (lions, zebras, wolves…)

- Community: when different species population share the same ecosystem and place.

    In a population living things the same specie can:

-form a family: lions, tigers.

-form an association: bees, ants (live in groups where every member has a specific role)

-have a gregarious association: storks (migrate in groups to protect from predators)

    In a community of different species can exist interspecific relationships:

-parasitism: a specie benefits from other specie damaging it (lices, ticks)

-mutualism: two different species benefit from each other (birds and hippos.

-comensalism: a specie benefits from other specie without damaging it (scavengers, orchids, hermit crab)
