Question

The study of interrelationships between living organisms in soil and their environment is called as
A. Phytogeography
B. Ecology
C. Phytosociology
D. Ecosystem

Answer 1

Hint: It is concerned with the study of the workings of natural ecosystems and the species they contain.

Complete Answer:
Living beings continuously interact with the environment to grow, reproduce and survive on earth. The environment is composed of physical elements such as soil, climate, temperature and other biotic components. Plants and animals are dependent on the environment and to each other. This is known as interdependence.

In the given options,
1) Phytogeography is the area of science that studies the spatial distribution of plant species and their impact on the earth's surface. Phytogeography involves all areas of plant distribution, from restrictions on the distribution of ranges of individual species to conditions affecting the makeup of whole populations and flora. Phytosociology is the study of classifications of plants and their relationships.

2) Ecology is the branch of science dealing with the study of the relationships between living beings and their physical environment. It gives information about the relationships between various species and also how changes in a physical environment can affect an ecosystem's organisms and the natural environment.

3) An ecosystem is defined as a group of plants, animals and other organisms that live and interact with the physical environment as a system. Both biotic and abiotic factors make up an ecosystem. Plants, animals and other organisms comprise biotic factors. Rocks, humidity and temperature comprise abiotic factors.

So, the correct answer is option B i.e., Ecology.

Note: Ecology is essentially a group of many fields of study. As a discipline, ecology is a wide field that includes various sciences such as biology, physics, chemistry, and geology.
