Answer:
Prokaryotes or unicellular organisms, without a nucleus, are categorized in two different kingdoms: Eubacteria and Archaebacteria or simply, bacteria and archaea, respectively. Sometimes these two kingdoms are also clubbed together as Monera. Unicellular organisms with a nucleus are part of the kingdom Protista.
Answer:
The trilobite is the oldest.
Explanation:
In general terms (disregarding specific examples), the lower the level in the stratosphere, the older it is. In this case, the lowest level is taken by the trilobite.
Note however, that this is not always the case, especially near edges of the plates. Sometimes plates shift, which can cause certain older fossils to be moved upwards, while newer ones are shifted downward, as one plate "eats the other". Territory creations, including valleys and mountains when plates crash into each other, can also shift where a fossil is located.

Decreased population will decrease the rate at which resource is consumed.
Option C.
<h3><u>Explanation:</u></h3>
Rate of resource utilization depends on the demand for resources among a population. The demand increases with the increase in population who actually uses the resource to increase their comfort.
With the increase in population and increased desire for resources, the rate of consumption of resources is increased. Decreased cost of harvesting the resources will led to wastage of resources, which will again increase the demand again.
So, decrease in population will only decrease the demand for resources. This will actually decrease the rate for the resource harvesting.
