Questions Related to human population

The sum total of the populations of the same kind of organisms constitute

population and how it changes human population ecology and environment zoology

  1. Colony

  2. Genus

  3. Community

  4. Species

Show answer
Correct Option: D
Explanation:

Species is a group of the same kind of the organisms.

Genus is a group of organisms which maybe of different species.
colony is usually an association of two or more different kind of organisms which live together usually in mutual relationships.
Community is a big group of organisms which may be of different kind but live together and use the same resources in the same area.
So the correct answer is' Species'.

The aggregate of process that determine the size and composition of any population is known as

population and how it changes human population ecology and environment zoology

  1. Population dynamics

  2. Population dispersal

  3. Population explosion

  4. Population density

Show answer
Correct Option: A
Explanation:

Population dynamics is a study of population. it includes size and age of a population, and also its composition. It considers these as dynamic systems. It also studies the biological environment affecting these dynamics.

So, option A is the correct answer.

Populations connected by dispersing individuals are called

population and how it changes human population ecology and environment zoology

  1. Demes

  2. Community

  3. Metapopulation

  4. Both B and C

Show answer
Correct Option: C
Explanation:
Metapopulation is a group of populations that are separated by space but consist of the same species. It is a population in which individuals are spatially distributed in a habitat to two or subpopulations.
So the correct answer is 'Metapopulation'.

Individuals having similar life cycle experiencing similar ecological parameters at similar stage of life cycle are

population and how it changes human population ecology and environment zoology

  1. Guild

  2. Population

  3. Ecocline

  4. Biotype

Show answer
Correct Option: B
Explanation:

"Population" is defined as a group of individuals of the same species living and interbreeding within a same given area. Members of a population often rely on the same resources and are subject to similar environmental constraints.

"Guild" is any group of species that exploit either same resources or different resources in related ways. Also, it is not necessary that the species within a guild occupy the same, or even similar  ecological niches.
"Ecoline"  is a physical transition zone. It is a variation of the physicochemical environment of one or two physicochemical factors.
"Biotype" is a group of individuals that are genetically identical but form a physiologically distinct race within a species, having dissimilar parameters.
Hence, answer is "Population".

population and how it changes human population ecology and environment zoology

  1. Malthus

  2. Spencer

  3. Mobius

  4. Odum

Show answer
Correct Option: A
Explanation:

Malthus termed population as "Self perpetuating unit" in his book, "An Essay on the Principle of Population," which was published in 1798.

Which among these represent a population?

population and how it changes human population ecology and environment zoology

  1. Spider and trapped files in its web

  2. All plants in a forest

  3. Earthworm that lives in grassland

  4. All the Oak trees in a forest

Show answer
Correct Option: D
Explanation:

A population is all the organisms that belongs to the same group or species and lives in a particular geographical area with the capability of interbreeding.

All the oak trees in a forest specifically mentions a species that is present in that geographical area.

Urban population of the world is

population and how it changes human population ecology and environment zoology

  1. 45%

  2. 39%

  3. 35%

  4. 30%

Show answer
Correct Option: A
Explanation:
The total population of the world is about 7.7 billion and out of this population, about 4.2 billion population is living in the urban area. So, the percentage of urban population of the world is about 55% which is near to 45% among all options given in the question.
So, the correct answer is '45%'.

A population is a group of

population and how it changes human population ecology and environment zoology

  1. Species in a community

  2. Communities in an ecosystem

  3. Individuals in a family

  4. Individuals in a species

Show answer
Correct Option: D
Explanation:

A group of different organisms with related characters of a same area is called population.

So the correct option is 'individuals in a species'.

A population consists of the number of individuals in-a given area at a particular time

population and how it changes human population ecology and environment zoology

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

 A population is a group of individuals belonging to a species occupying a given area at a particular time

So, the correct option is 'True'

Match column I with column II and choose the correct option from the given codes.

Column I Column II
A. Population (i) Part of the earth consisting of all the ecosystems of the world
B. Community (ii) Assemblage of all the individuals belonging to different species occurring in an area
C. Ecosphere (iii) Group of similar individuals belonging to the same species, found in an area
D. Ecosphere (iv) Interaction between the living organisms and their physical environment
(v) Classification of organisms based on the type of environment
population and how it changes human population ecology and environment zoology

  1. A-(iii), B-(ii), C-(i), D-(v)

  2. A-(iv), B-(v), C-(iii), D-(i)

  3. A-(ii), B-(iii), C-(i), D-(iv)

  4. A-(iii), B-(ii), C-(iv), D-(i)

Show answer
Correct Option: D
Explanation:
 Column I  Column II
 A. Population  A group of individuals of the same species occupying a particular geographic area. Populations may be relatively small and closed, as on an island or in a valley, or they may be more diffuse and without a clear boundary between them and a neighboring population of the same species.So the correct option is 'group of similar individuals belonging to same species, found in an area'.
 B. Community  A community is a small or large social unit (a group of living things) that has something in common, such as norms, religion, values, or identity. Communities often share a sense of place that is situated in a given geographical area (e.g. a country, village, town, or neighborhood) or in virtual space through communication platforms. Although communities are usually small relative to personal social ties (micro-level), "community" may also refer to large group affiliations (or macro-level), such as national communities, international communities, and virtual communities.So the correct option is 'assemblage of all the individuals belong to different species occurring in an area'. 
 C. Ecosphere  An ecosphere is a planetary closed ecological system. In this global ecosystem, the various forms of energy and matter that constitute a given planet interact on a continual basis. The forces of the four Fundamental interactions cause the various forms of matter to settle into identifiable layers.So the correct option is 'interaction between the living organisms and their physical environment'.
D. Ecosphere The biosphere of the earth or other planet, especially when the interaction between the living and nonliving components is emphasized.So the correct option is 'Part of the earth consisting of all the ecosystems of the world'.
