-What environment means.
-What biological environment means.
-What physical environment means.
BUT WHAT IS AN
ECOSYSTEM?

A FEW VIDEOS TO HELP YOU
UNDERSTAND THESE CONCEPTS:
18. Feeding
relationships
• One living thing
often feeds on
another.
Competition
• Living things
compete for the
same resources
(food, water,
space, oxygen…).
Cooperative
relationships
• Living things join
together for a mutual
advantage.
RELATIONSHIPS BETWEEN LIVING
THINGS
19. THE BIOSPHERE
It is the part of the Earth where LIVING THINGS are found.
There are many different ECOSYSTEMS in the BIOSPHERE.
It is the part of the Earth where LIVING THINGS are found
24. KEY CONCEPTS
Environment: is made up of the physical and the biological environment.
-Physical environment: the combination of non-living things.
-Biological environment: the combination of living things.
-Species: group of individuals with similar characteristics that can
reproduce within their group.
-Population: all of the individiuals of the same species living in a
particular place.
-Community: all the populations living in a particular place.
Ecosystem: the combination of the community and the surrounding
physical environment.
Biosphere: the part of the Earth where living things are found.
