Question

Of the following weather factors, which is most important in determining the plant and animal populations that can exist in an area? (2 points)

air pressure
humidity
precipitation
wind direction

Answer 1

I think it's precipitation

Answer 2

The correct option is PRECIPITATION.
Precipitation refers to the different types of liquid which fall from the sky, such liquids include rain, snow, hail, etc. The quantity of precipitation that is available on a yearly basis is the principal determinant of the type of plants and animals that will be found in a particular place, this is because plants and animals depend heavily upon water to survive. Plants and animal populations will be higher in a place, where the quantity of precipitation experienced is high. The reverse is also true.
