Hint: The biophysical environment comprises two component-biotic and abiotic components. There is a constant interaction between these components. The interactions help in the movement of material and energy flow through the living community.

Complete Answer:
The living organisms constantly interact with their surroundings. A community of living organisms continuously interact with the non living components of their environment. This interacting system is called an Ecosystem. It comprises biotic and abiotic components which are linked through nutrient cycles and energy flow.
The example of an ecosystem is the marine ecosystem.
The ecosystem is controlled by both internal factors like biomass within an ecosystem and external factors like temperature, climate etc. The study of these interactions is known as ecology.
Ecology addresses the full scale of life from tiny bacteria to the entire solar system. Ecologists study the diverse and complex relations among the species like pollination, predation etc. Ecology has practical applications in conservation, resource management, community health, human social interactions.
Phytosociology is the branch of science which deals with the plant communities, composition, and relationship between the species within them.
Phytogeography is the branch of botany which deals with the geographical distribution of plants.

The correct answer is (C). The study of inter-relationship between living organisms and their environment is known as ecology.

Note: Ecology is the branch of science that studies how people or organisms relate to each other and their environment. An example of ecology is study of the food chain in deserts.
