All plants, animals and other organisms that make up a distinct natural community in any climatic region is known as the

  1. Biome

  2. Biounit

  3. Biomagnification

  4. Biological ecosystem
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A biome  is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. "Biome" is a broader term than "habitat"; any biome can comprise a variety of habitats. hile a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A 'biota' is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-time scale spatiotemporal scales. The biotas of the Earth make up the biosphere.

So the correct option is 'biome'.

  1. Synecology

  2. Autecology

  3. Cybernetics

  4. Edaphology
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Synecology is the branch of science which deals with the study of plants or animal groups or communities.
Autecology is the study of particular species of the living forms.
Cybernetics is the interdisciplinary study of the structure of complex systems. It is a science of automatic control system in any complex structure like living things and machines.
Edaphology is the study of the role of soil in the environment and its contribution to the living world.
Thus, the correct answer is option C.
