Study of ecology of population is called as

population and how it changes human population ecology and environment zoology

  1. Autecology

  2. Synecology

  3. Ecosystem

  4. Demecology

Show answer
Correct Option: D
Explanation:
Autecology is the study of the interactions of an individual organism or a single species with the living and nonliving factors of its environment. 
Synecology is the branch of science that deals with the natural community and its environment.
An ecosystem is a community of living organisms where the biotic and abiotic components interact with each other.
Demecology is that branch of biology which deals with the ecology of populations
Therefore, the correct answer is option D

Organisms belonging to the same species form a

population and how it changes human population ecology and environment zoology

  1. Population

  2. Community

  3. Ecosystem

  4. Trophic level

  5. Guild

Show answer
Correct Option: A
Explanation:

Species is the basic unit in a biological classification and taxonomic ranking system. Generally, species is defined as a group of organisms in which two individuals are capable of reproducing their offspring, Organisms belonging to the same species in a particular locality is termed as population. 

Smallest unit to evolve through natural selection is

population and how it changes human population ecology and environment zoology

  1. Cell

  2. Clade

  3. Organism

  4. Population

  5. Species

Show answer
Correct Option: D
Explanation:

According to Darwin, evolution happens through natural selection which is a differential success in reproduction and adaptation of the organisms to their environment. The population is defined as a group of interbreeding organisms belonging to a particular species and sharing a common geographic area. Thus the smallest unit that can evolve through natural selection is the population. Thus, the correct answer is option D.

An example of population is

population and how it changes human population ecology and environment zoology

  1. All the honeybees in an orchard in one spring

  2. All the plants and animals in a forest

  3. The living and nonliving factors in a meadow

  4. The life in Earths atmosphere

  5. All the buffalo in 1840

Show answer
Correct Option: A
Explanation:

The term population refers to the number of animals or people in a particular place. The term also includes  group of similar organisms living in the same region or habitat such as organisms of the same species or number of honeybees in an orchard in one spring.
