Which of the following factors would have the smallest impact on a population’s size?
a.
the total number of organisms
b.
the available water supply
c.
the variety of organisms
d.
adequate shelter

The correct answer is option C. the variety of the organisms.

The population size can be defined as the actual number of the individuals present in an organism. The presence of the variety of the organism does not effect the population size as they do not have any effect on the reproduction.

The total number of the organism has a direct impact on the population size of the organism. In case, the total number of the organism is high, the population size would increase at a higher rate, and if the total number of individual are less than the population would not  increase  at a higher rate.

The available water supply and adequate shelter would also effect the size of the population. In case, the adequate shelter and the water supply would be available, then in the presence of the abundant resources, the organism would reproduce at a higher rate and the population size would increase, and the opposite occur in lack of resources, in the absence of adequate resource, the organism reproduce at a slower rate and mortality can be high.

The answer is C. the variety of organisms

Explanation:

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
