Q.
Read the following statements and select the correct option:
Biodiversity is the number and types of organisms on earth.
Biodiversity differs from place to place.
Solution:
Biodiversity, a portmanteau of biological and diversity, generally refers to the variability of life forms on Earth. As per the United Nations Environment Programme (UNEP), biodiversity measures variation at the genetic, species, and ecosystem levels.
Terrestrial biodiversity tends to be more prominent near the equator, which seems to be the resultant of the warm climatic conditions and high primary productivity.
Biodiversity is distributed unevenly on Earth and is most affluent in the tropical regions. These tropical forest ecosystems cover less than around 10% of Earth's surface area and contain about 90 % of the world's species.
Marine biodiversity tends to be the highest along the coasts in the Western Pacific, where the sea surface temperature is highest.
There are latitudinal gradients in species diversity. Biodiversity usually tends to cluster in hotspots and has been increasing through time, but will be likely to slow in the future.
