Ecosystem:(Biomes are large                        ecosystems).....                                             
An ecosystem
includes all of the living things   and the nonliving things in an area.                 
Within any ecosystem are  populations of        organisms.                                                    
When we talk about the population of a city, we mean the number of humans living in that city. 
In an ecosystem, a population is the number of members of a single species living in that       area. Together, the populations of the         many species living together in an area      are called a community.
