Question

The totality of genes, species and ecosystem of a region is known as
A. Biosphere
B. Biodiversity
C. Bioconservation
D. Bio community

Answer 1

Hint: Ecosystem is the whole of the species of every kind on our planet Earth. There are units that make this large biome possible. The change in the basic unit will affect all the rankings in the hierarchy thereby, affecting the largest ranking. Ecology is the sum of all the different varieties in our surroundings.

Step by step answer:Ecological hierarchy means the ranking of the ecological members. Every species existing in the universe make the ecology. So the hierarchy places them in order- individual, population, community, ecosystem, biome, biosphere. There are biotic and abiotic factors on the earth. Biotic includes the living matter whereas the abiotic factors include the non-living matter like rocks. The ecosystem is made up of many communities spread in larger areas. They all have different characteristics but live in the same atmosphere under the common universe. Community is the gathering of different populations. Different species populations make the community of an area.
Option A: Biosphere: It forms the ecological system in which all the biotic and abiotic beings reside.
Option B: Biodiversity: The organic beings prevailing on this Earth including all the species form biodiversity.
Option C: Bioconservation: It is the protection of all biological beings from extinction.
Option D: Bio community: An ecology formed of different organisms is biocommunity.
So the answer is option B: Biodiversity

Note: Biodiversity is important for the ecosystem. Every species has an important role in the maintenance of ecology. The disasters can exploit the ecosystem but if the biodiversity is high and rich, the ecosystem will recover or heal fast.
