ANSWER : a wide range of environmental conditions that shapes communities. 
Explanation:
Climate can easily be described as the average weather which occurs in a place over a long period of time probably over many years. The ecosystems and habitats around the earth are shaped due to climate as particular climate can be best for the living condition of one organism but be devastating for the living of another organism. The effect of climate on living communities is such devastating that a change in climate can cause the extinction of a particular kind of species. Climate shall not be confused with weather which is day to day temperature change.
