Question

A branch of ecology which is concerned with the study of individual species at all stages of its cycle in relation to environment is called
A. Ecological niche
B. Synecology
C. Autecology
D. Reproductive ecology.

Answer 1

It is a theory focused on species as the most important unit of biological organization, as individuals across all populations of a particular species share species-specific adaptations that influence their ecology.

Complete answer:
To answer this question, first, we need to know the ecology. Ecology is the phenomenon of how organisms interrelate with one another and with their physical environment. The abundance and distribution of organisms on Earth is formed via biotic, abiotic factors. Ecology is considered at many levels, contains organisms, ecosystem, biosphere, community and population.
Now, let us find the solution from the option.

Ecological niche refers to the role and position of a species in an environment.
Synecology is the phenomenon of the interrelation of a variety of species in a community and their surroundings.
Autecology is the division of ecology that describes the biological relationship between an individual organism or an individual species and with their environment.
Reproductive ecology is the connection of the physiology of an organism with the environment.

Thus, the correct option is ‘C’. i.e. Autecology.

Note: Autecological theory associated the different species needs and environmental tolerances of individuals to the geographic distribution of the species, with individuals tracking favorable conditions, having the capability for migration in their life cycles. Autecology has a strong foundation of evolutionary theory; it consists of the theory of punctuated equilibrium and the recognition conception of species.
