Habitat - Answers - is where a particular orgamism or population interacts with the
physical environment (where they live)-many habitats within one ecosystem
Niche - Answers - the role of the organism plays in the ecosystem (how they live) - e.a
grouse eat plants and insects

ecosystems
Biosphere 2 - Answers - the largest artifiacally created self-sustaining ecosystem.
Eventually failed moselt because of insect loss
Indicator species - Answers - Species that serve as early warnings that a community or
ecosystem is being degraded. Example- the grasshopper sparrow
