I think that this is a true statement: it's better than determining the population size by indirect means, for example by judging how much food they ate or by judging by just a sample of the population. I would maybe add that this method can be supported by technology, for example taking a picture of the population and analyzing the picture later.

What is one way that matter moves from<br> the geosphere to the hydrosphere?

Alisiya [41]

Water in the geosphere can be discharged into surface water, becoming part of the hydrosphere once again, or it could be drawn up into the roots of a plant and become part of the biosphere. Water in the biosphere can be released into the atmosphere through transpiration in plants, or respiration in animals.
