Question

Autecology deals with
A. Ecology of species
B. Ecology of many species
C. Ecology of community
D. All the above

Answer 1

Hint: Ecology is defined as the total relations of organisms to each other, to the environment, and to the entire energy balance within the given ecosystem. It is an interdisciplinary field that includes biology, geography, and earth science.

Complete answer: The ecology is traditionally studied at two levels.
AUTEOCOLOGY: The study of the relationship between the environment and an organism or a species is called autecology
SYNEOCOLOGY: The study of the relationship between the environment and a community is termed synecology.
Population ecology is covered by autecology and synecology includes community ecology and ecosystem ecology.
So, the correct answer is option A-Ecology of species.

Additional information :
No organism lives itself alone. It must live in the same environment with other organisms of its kind and with those of other species. It may eat up other organisms, be eaten by others, and compete with others for the necessities of life such as space, food (sunlight in case of plants), protection, mate, etc. It must also continually make adjustments to its physical environment. Every organism is thus, influenced by and influences the life and physical environment around it. Ecology is basically concerned with four levels of biological organization – organisms, populations, communities, and biomes. Ecology at the organism level is essentially physiological ecology which tries to understand how different organisms are adapted to their environments in terms of not only survival but also reproduction.

Note: Ecology provides the foundation for our understanding of agriculture, forestry, and fisheries. It is an interdisciplinary science linking physical, biological, and social sciences. German biologist Ernst Haeckel (1869) first coined the term ecology.
