Question

The science that deals with various inter-relationship between various organisms and their physical environment is called-
A)Geology
B)Geomorphology
C)Ecosystem
D)Ecology

Answer 1

Hint: Our environments consist of all the living and nonliving things that occur naturally. The living component of our environments includes plants, animals, bacteria , fungi etc.

Complete answer: Our environment shapes every organism and hence its important to study the relationship between environment and various organisms. Let us look at the options given to us.
Option A-Geology is the study of the physical structure of earth, theri evolution, the rocks and the processes which act on them.
Option B-Geomorphology is the study of evolution of topographic and underwater features. It studies how physical , chemical and biological processes create these landforms.
Option C- Ecosystem is a geographical area where the biotic and abiotic components of the environment interact and live together. These components are related to each other through nutrient cycles and energy flows.
Option D- Ecology is the science that studies the interaction between organisms and their environments. They study life processes, biodiversity of organisms, adaptations and habitats etc. They try to develop an understanding of these interactions at the levels of organism, population, community, biosphere and ecosystem. The subject of ecology,hence, is further divided into global ecology, landscape ecology , community ecology, population ecology , ecosystem ecology and organismal ecology.

Therefore the correct answer is option (D).

Note: The subject of ecology is important for environmental conservation, energy conservation , eco friendliness and resource allocation.Ramdeo Misra is revered as the Father of Ecology in India. His work is on tropical communities and their succession, environmental responses of plant populations and productivity and nutrient cycling in tropical forest and grassland ecosystems
