6. They are all Ecosystems
Ecosystem is all of the organisms that live in a region and interact with each other and their environment

7. Ecosystems
Within an Ecosystem are its living and non-living components
Called Biotic and Abiotic Factors

Water
Sunlight
Soil
Air

39. Organism An individual Organism of a specific species.
Species a group of living organisms consisting of similar individuals capable of interbreeding.(make babies who can also make babies)

40. Population
All of the same species in an area

41. Community
All of the different populations in an area

42. Ecosystem
All of the different populations in an area (Community) and the non-living (Abiotic) factors

43. Biosphere
All of the parts of the Earth that contain life.
