5. Organization in the Environment
The environment can be organized into different
levels
First level = individual organism
Second level =larger, made up of similar
organisms which form a population
Third level =made of different populations,
which form a community
Fourth level =made of a community and all its
abiotic factors, which form an ecosystem
Fifth level =all ecosystems, forms a biosphere
11. Summary
• All living things are connected in a web of
life.
• The biotic part of an environment is made
up of all the living things found within it.
• The abiotic part of an environment is made
up of all of the nonliving things found
within it, such as water and light.
• An ecosystem is made up of a community
of organisms and its abiotic environment.
