Case Based Questions Test: Organisms & Populations - Question 1

Population is a group of individuals of a single species living in a given area. It includes spatial arrangement, genetic variation and the dynamics including natality, mortality, biotic potential, carrying capacity, etc. Population structure includes features as density, abundance, spacing, genetic variations. The genetic structure reveals genetic variations and population size.

Q. ______ is the study of the ecology of population.

Q. Which Indian state has the least population growth?

Detailed Solution for Case Based Questions Test: Organisms & Populations - Question 2

Correct option is Kerala.

Kerala: Kerala has the least population growth rate among Indian states. The state has successfully implemented various population control measures and family planning programs, resulting in a lower population growth rate compared to other states. Kerala has the least population growth, which has the highest population growth.

Air, water, soil, biota, temperature and light are the major environmental factors that directly affect the flora and fauna in different geological areas of the earth.

Q. Hydrological cycle is concerned with :

Detailed Solution for Case Based Questions Test: Organisms & Populations - Question 8
Lithosphere is concerned with land, hydrosphere with water bodies and atmosphere is concerned with space. Hydrological cycle circulates in all these three subsystems.
Case Based Questions Test: Organisms & Populations - Question 9

Read the following text and answer the following question on the basis of the same :

All biomes of the earth constitute the earth's ecosystem. All flora and fauna occur in the lithosphere, atmosphere and hydrosphere along with their environments. Air, water, soil, biota, temperature and light are the major environmental factors that directly affect the flora and fauna in different geological areas of the earth.

Directions : In the following questions a statement of Assertion (A) is followed by a statement of reason (R). Mark the correct choice as :

Assertion (A) : Some organisms like Salmon are known as Euryhaline.

Reason (R) : Euryhaline can tolerate a wide range of salinities.

Detailed Solution for Case Based Questions Test: Organisms & Populations - Question 9
Euryhaline animals like salmon can adopt a wide range of salinity as they are found in areas where rivers and sea meet.

Case Based Questions Test: Organisms & Populations - Question 11

Read the following text and answer the following question on the basis of the same:

Growth of a population with time shows specific and predictable patterns. Two types of growth pattern of population are exponential and logistic growth. When resources in the habitat are unlimited each species has the ability to realize fully its innate potential to grow in number. Then the population grows in exponential fashion. When the resources are limited the growth curve shows an initial slow rate and then it accelerates and finally slows giving the growth curve which is sigmoid.

Q. Identify the incorrect statement:

In logistic growth the population seldom grows beyond the carrying capacity of the ecosystem.

dN/dt = rN(K-N)/K

What does 'r' represent in the given equation?

Detailed Solution for Case Based Questions Test: Organisms & Populations - Question 12
'r' represents Intrinsic rate of natural increase.
Case Based Questions Test: Organisms & Populations - Question 13

Growth of a population with time shows specific and predictable patterns. Two types of growth pattern of population are exponential and logistic growth. When resources in the habitat are unlimited each species has the ability to realize fully its innate potential to grow in number. Then the population grows in exponential fashion. When the resources are limited the growth curve shows an initial slow rate and then it accelerates and finally slows giving the growth curve which is sigmoid.

Q. Identify the correct equation that represents the exponential population growth curve:

Detailed Solution for Case Based Questions Test: Organisms & Populations - Question 13

At the constant birth rate in population through time and is never limited by food or disease, known as exponential growth. 
The formula of exponential growth is dN/dt=rN where dN/dt is the rate of change in population size, r is the biotic potential and N is the population size.

Case Based Questions Test: Organisms & Populations - Question 14

Read the following text and answer the following question on the basis of the same:

Growth of a population with time shows specific and predictable patterns. Two types of growth pattern of population are exponential and logistic growth. When resources in the habitat are unlimited each species has the ability to realize fully its innate potential to grow in number. Then the population grows in exponential fashion. When the resources are limited the growth curve shows an initial slow rate and then it accelerates and finally slows giving the growth curve which is sigmoid.

Q. Study the population growth curves (A and B) in the given graph and select the incorrect statement:

Detailed Solution for Case Based Questions Test: Organisms & Populations - Question 14

Since resources of growth for most animal populations are finite and become limiting sooner or later, the logistic growth model is considered as more realistic.

Case Based Questions Test: Organisms & Populations - Question 15

Read the following text and answer the following question on the basis of the same:

Growth of a population with time shows specific and predictable patterns. Two types of growth pattern of population are exponential and logistic growth. When resources in the habitat are unlimited each species has the ability to realize fully its innate potential to grow in number. Then the population grows in exponential fashion. When the resources are limited the growth curve shows an initial slow rate and then it accelerates and finally slows giving the growth curve which is sigmoid.

Q. The equations correctly represents Verhulst-Pearl logistic growth is:

Detailed Solution for Case Based Questions Test: Organisms & Populations - Question 15
S-shaped growth curve is also called Verhulst-Pearl logistic curve and is represented by the following equation.

where dt/dN = rate of change in population size, r = intrinsic rate of natural increase, N = population density, K= carrying

capacity and = environmental resistance.
