Question

Interaction between biotic and abiotic factors is called as______.
A. Ecology
B. Ecosystem
C. Niche
D. Biomes

Answer 1

Hint: Ecosystem includes different biotic and abiotic factors. They interact with each other to maintain proper balance in the environment. Study of ecosystems is called ecology. Niche is the study of interaction of organisms in a particular area. Biomes are the major ecosystems.

Complete step by step answer: Biotic factors include all the living organisms while abiotic factors include non-living factors such as light, air, soil, rock, minerals, water etc. Abiotic factors help living organisms to survive. Sunlight is the energy source and air (CO2) helps plants to grow. Rock, soil and water interact with biotic factors to provide them nutrition. Interaction between biotic and abiotic factors helps to change the geology and geography of an area.
 Different types of interaction between biotic and abiotic factors are observed in an ecosystem. Ecologists study these interactions in detail. Ecology is the study of interaction between biotic and abiotic factors.
The niche of any organism depends how that particular organism responds and reacts to the distribution and abundance of abiotic factors. For example: in the presence of abundant resources, population grows exponentially and provides more resources for predators.
A biome is a group of plants and animals that have common characteristics for the environment they exist in. It is a broader habitat. For example: Tundra region, temperate region and many more.
From the above information we know that the ecosystem shows interaction between biotic and abiotic factors.
So, the correct answer is option B.

Note: Ecosystem can be determined by the particular material and the climate. It contains flora and fauna. Aquatic ecosystem, tropical ecosystems are the most diverse ecosystems which have a variety of species in them. Terrestrial, forest, grassland, desert, tundra, freshwater and marine ecosystems are seven main ecosystems. Tropical rainforests have half of the world’s species living in it.
