Question

The study of the total number and types of organisms present on earth is
(a)Ecology
(b)Taxonomy
(c)Biodiversity
(d)Classification

Answer 1

Hint: This is generally referred to as a measure of difference at the genetic, species, and ecosystem level. It can be used more precisely to mention all the living species in one region or ecosystem that includes plants, bacteria, animals, and humans.

Complete answer:
Biodiversity is the variability and variety of life on earth that includes the study of the total number and types of organisms present on earth. The diversity of all living organisms depends on some factors such as temperature, altitude, precipitation, soils, geography, and the presence of other species.

Additional Information: -The biodiversity in the terrestrial region is generally high near the equator which is the result of the warm climate and high primary productivity.
-Biodiversity is the richest in the tropical region.
-The time of emergence of humans has shown an ongoing biodiversity reduction and an accompanying loss of genetic diversity.
-Terrestrial biodiversity is considered up to 25 times greater than ocean biodiversity.
-Ecosystem services involve a group of benefits that ecosystems provide to humans.
-The health risks of climate change are associated with changes in biodiversity.
-Habitat destruction also played an important role in the extinction of species, especially with tropical forest destruction.
-When a resource is consumed at an unsustainable rate, it leads to overexploitation.
Taxonomy: Taxonomy deals with the classification, naming, and describing all living organisms including plants.
Classification: It is a critical component of the taxonomy process which is the arrangement of animals and plants according to their observed similarities.
Ecology: Ecology is the study of interactions among organisms and to their physical surroundings.
So, the correct answer is ‘biodiversity.’

Note: -A biodiversity hotspot is a region with a high level of endemic species that have experienced great habitat loss.
-Global warming is a major risk to global biodiversity.
-National parks and nature reserves are the area used to preserve the endangered species.
