The carbon footprint of an activity is used to assess environmental pollution. what does it measure?

well we can't tell you because we cant see the time give a screen shot or something.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
