Question

Degree of biodiversity increases from:
A. Equator to poles
B. Polar to equator
C. Low latitude to high latitude
D. Low altitude to high altitude

Answer 1

Hint: The terms "biodiversity" are most frequently used in place of species diversity and species richness, which are more precisely defined and well-established terminology. The term "diversity" is used by biologists to refer to the "totality of genes, animals, and ecosystems in a place."

Complete step-by-step answer:

The world's biodiversity is not spread equally; rather, it varies widely between and within regions. The variety of all living things (biota), among other things, is influenced by climate, precipitation, height, soils, geography, and the existence of other species. Biogeography is the study of the geographic distribution of organisms, species, and ecosystems.

Because of the warm environment and high primary productivity in the area close to the equator, the tropics typically have higher levels of biodiversity than other parts of the planet. Less than 10% of the earth's surface is occupied by these tropical forest ecosystems, which are home to 90% of all species. The mid-latitudinal belt of all oceans and the shores of the Western Pacific, where the sea surface temperature is highest, typically have higher levels of marine biodiversity.

From poles to equators, high altitude to low altitude, and high latitude to low latitude, the degree of biodiversity increases.

Therefore here option B is correct.

Note: As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator). While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances. This makes it possible for a number of species to emerge and flourish.. On a mountain, there is a decline in species variety as you go up in elevation. One of the main factors affecting the reduction of diversity is the drop in temperature and increased seasonal fluctuation at higher altitudes.
