Question

Choose the incorrect statement about regulation of populations,
P. The exponential equation reflects the effect of density-dependent factors.
Q. The logistic model shows a sigmoid curve when population size plotted against time.
R. Density-independent factors effects decreases with decrease in population's density.
S. Population cycles in some populations may occur due to crowding or lag times in the
response to density-dependent factors.
a. P and R
b. Q and S
c. Only R
d. All of the above​

Answer 1

answer is C. Only R

thanks i hope this ans.is useful for you

Answer 2

Answer:

The incorrect statement from the given options is (R) Density-independent factors effects decreases with decrease in population's density.

Explanation:

Density-independent factors affect the per capita population growth rate and is independent of the population’s density. The density-independent factors does not depend upon the population’s size, but these type of factors can be catastrophic to smaller populations, especially populations with a limited geographic range.

What do you understand by regulation of population?

The term "population regulation" refers to ecological processes (biotic and abiotic factors) that control birth and death rates in order to control population increase.

It is known as a limiting factor when ecological considerations prevent population expansion. Density-dependent and density-independent limiting variables are the two types of constraints.

Based on a population's density, density-dependent limiting variables affect the rate of growth per capita. As the population grows, these elements will typically cause the growth rate to slow. A logistic increase is what this is. No matter how big or small a population is, if its growth rate is constant, it will always increase in size exponentially.

Abiotic factors are one type of density-independent factor and are probably the best example.

These populations experience cycles of growth leading to the reduction in size in oscillating patterns known as cyclical oscillations.
