So, if the birthrate and the death rate are the same, that means that for every person that gets born, one person dies: so the number of people would stay constant. This means that the growth rate is actually 0%.
Properly identifying each species.
Accurately recording his findings.
Not interfering with ecosystem while studying the birds.
Calcium is few of the main sources for healthy bones, teeth, and muscles.
Answer: C. Dead snake fossilizing underground.
A fossil fuel is the fuel that is formed by natural processes, such as anaerobic decomposition of dead plants and animals underground. These organisms and their remains remain deep inside the depth of numerous layers of soil resulting in fuel produced after millions of years. A carbon sink refers to a natural or artificial reservoir that stores and absorbs atmospheric carbon by physical and biological process. The formation of fossil fuel inside the earth is carbon sink.
Dead snake will be added as a matter on which biological activity called as decomposition will take place. The organic matter of dead snake will be decomposed by microbes in the soil. The organic matter being the source of carbon, after decomposition will become the reservoir of carbon in the form of fossil fuel.
Therefore, dead snake fossilizing underground is the example of carbon source becoming a carbon sink.
the answer is d. break down matter from dead plants and animals
