Answer:
The Mark-Recapture technique is used to estimate the size of a population where it is impractical to count every individual. The basic idea is that you capture a small number of individuals, put a harmless mark on them, and release them back into the population.
Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume. Ecologists often estimate the size and density of populations using quadrats and the mark-recapture method.
Wildlife managers use 4 general approaches to estimate population sizes of wildlife: total counts, incomplete counts, indirect counts, and mark-recapture methods.
The answer is counting individuals and mark-and-recapture.
C - By exhaling/ breathing out
I think It depends on how much mass an object has and how much force is in between the two objects.
The four types of fossils are:
<span><span>mold fossils = (a fossilized impression made in the substrate - a negative image of the organism)
</span><span>
cast fossils = (formed when a mold is filled in)
</span><span>
trace fossils = ichnofossils (fossilized nests, gastroliths, burrows, footprints, etc.)
</span><span>
true form fossils= (fossils of the actual animal or animal part).</span></span>
