  4. All of the above

Answer: 4. All of the above

  • Ecology is the branch of biology that deals with the characteristics and living styles of different types of animals or plants and the relation they share with each other.
  • Ecology also indicates the relationship of different types of animals with the environment. It consists of environmental factors such as climate, temperature, and rainfall. It also indicates the relationship that the plant shares with the ecosystem. Thus, option (4) is correct.

  2. Physiological ecology
  3. Habitat ecology
  4. None of the above

Answer: 2. Physiological ecology

Ecology at the organism level is essentially called physiological ecology which tries to understand how different organisms are adapted to their environments in terms of not only survival but also reproduction.

Question 7. Taxonomy hierarchy refers to

  1. Stepwise arrangement of all categories for classification of plants and animals
  2. A group of senior taxonomists who decide the nomenclature of plants and animals
  3. A list of botanists or zoologists who have worked on the taxonomy of a species or group
  4. Classification of a species based on fossil record

Answer: 1. Stepwise arrangement of all categories for classification of plants and animals

Taxonomy hierarchy refers to the stepwise arrangement of all categories for plants and animals. It is a method of grouping together living organisms that share common features.

Question 8. The basic unit of ecological hierarchy is

  1. Species
  2. Genus
  3. Individual organism
  4. Microorganism

Answer: 3. Individual organism

The individual organism is the basic unit of ecological hierarchy as it continuously exchanges material and information with its environment. It is a distinct living entity having all life processes in its body separate from those in other individuals.

Question 9. Ecological hierarchy comprises, which of the following sequences?

  1. Population → species → organism → ecosystem → biosphere
  2. Species → population → community → ecosystem → biosphere
  3. Ecosystem → population → biosphere → community → organism
  4. Species → population → biosphere → ecosystem → community

Answer: 2. Species → population → community → ecosystem → biosphere

Ecologists study organisms ranging from various levels of organization. The ecological hierarchy sequence is Species → Population → Community → Ecosystem → Biosphere.

Question 10. The branch of ecology which deals with the study of individual species at all stages of their life cycle in relation to the environment is called

  1. Autecology
  2. Synecology
  3. Reproductive ecology
  4. Niche ecology

Answer: 1. Autecology

An autecology is an approach in ecology that seeks to explain the distribution and abundance of species by studying the interactions of individual organisms with their environments.

Question 11. The study of the interrelationship between an entire community and its environment is called

  1. Autecology
  2. Synecology
  3. Species ecology
  4. None of the above

Answer: 2. Synecology

Autecology and synecology are two main branches of ecology. Synecology is the study of a group of organisms of different species that are associated together as a unit in the form of a community. Also known as community ecology.

Question 12. Synecology is the study of

  1. Single species
  2. Abiotic environment
  3. Group of species
  4. Ecological reaction

Answer: 3. Group of species

Synecology deals with the study of groups of organisms or species that are associated together as a unit, for example, a forest. It is concerned with structure, nature, and the development of that community.

Question 13. The sum total of the populations of the same kind of organisms constitute

  1. Colony
  2. Genus
  3. Community
  4. Species

Answer: 4. Species

A species is a group of individuals of the same kind of phenotypic characters and can interbreed easily.

Question 14. A community is defined as

  1. A group of birds
  2. A collection of species
  3. Interacting population
  4. An interactive ecosystem

Answer: 3. Interacting population

A community is formed when more than one organism shares the same habitat and interacts with each other. It is constituted by populations of different species of plants, animals, and microorganisms (bacteria and fungi) in a specific structure that permits interactions amongst them.

Question 15. In increasing order of organizational complexity, which one of the following is the correct sequence?

  1. Population, species, community, ecosystem
  2. Population, variety, species, ecosystem
  3. Population, ecosystem, species, community
  4. Species, variety, ecosystem, community

Answer: 1. Population, species, community, ecosystem

  • In increasing order of organizational complexity, the correct sequence is Population, Species, Community, and Ecosystem Population is a group of similar individuals in a particular area that share or compete for similar resources and can potentially interbreed.
  • A species is a group of individuals of the same kind of phenotypic characteristics and can interbreed among themselves. A community is a group of two or more different species occupying the same geographical area at the same time.
  • The ecosystem is the community of living organisms in conjunction with non-living components of their environment, interacting as a system.

Question 16. A biome is

  1. A sum of ecosystems in a geographical area
  2. A sum of all ecosystems on the earth
  3. Biotic component in a population
  4. Biotic components in an ecosystem

Answer: 1. Sum of ecosystems in a geographical area

A biome is an area classified according to the species that live in that location. It is a zone characterized by climate, soil, principal vegetation, and the ecosystems that are sustained in it. So, a biome is the sum of ecosystems in a geographical area.

Question 17. The plants and animals living in a given area form

  1. Biological community
  2. Ecotone
  3. Biome
  4. Consociation

Answer: 1. Biological community

A biological community is the assemblage of interdependent and interacting populations of different species present in an area.

Question 18. Population is

  1. Group of similar interbreeding individuals in a particular area that competes for similar resources
  2. Group of dissimilar individuals in a particular area which competes for similar resources
  3. Group of anatomically similar individuals in a particular area which need dissimilar resources
  4. Interbreeding species together make a population

Answer: 1. Group of similar interbreeding individuals in a particular area that competes for similar resources

Population is a group of similar individuals in a particular geographical area that share or compete for similar resources, and potentially interbreed. Different populations of the same organism present in a particular geographical area are called local populations or domes.

Question 19. A group of two or more plant species is called as

  1. Plant community
  2. Animal ecosystem
  3. Plant ecosystem
  4. Ecological niche

Answer: 1. Plant community

A plant community (sometimes phytocoenosis or phytocenosis) is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types.

Question 20. Which of the following causes a species to be different from others and maintain its own specificity?

  1. Microevolution
  2. Macroevolution
  3. Genetic adaptation
  4. Climatic variations

Answer: 1. Microevolution

Microevolution is a change in gene frequency within the population of a species. In this evolution, change can be seen over a short period of time, i.e. between one generation and the next. This therefore leads to a species being different from others and maintaining its own specificity.

Question 21. Difference between population and community.

  1. Population is the grouping of individuals of the same species in the same place
  2. Community is the grouping of individuals of the same species at the same place at the same time
  3. Population is the grouping of individuals of different species at the different place
  4. Community is the grouping of individuals of different species in the same place at the same time

Answer: 4. Community is the grouping of individuals of different species at the same place at the same time

Community is the grouping of individuals of different species at the same place at the same time. A population is a member of all the organisms of the same group or species who live in a particular geographical area and are capable of interbreeding.
