Q. I. Higher latitude $\overset{Biodiversity\ increases}{\rightarrow}$ Lower latitude (Poles) (Equator) II. Higher latitude $\overset{Biodiversity\ decreases}{\rightarrow}$ Lower latitude (Poles) (Equator) III. Higher latitude $\overset{Biodiversity\ increases}{\rightarrow}$ Lower altitude (Mountain top) (Sea level) IV. Higher latitude $\overset{Biodiversity\ decreases}{\rightarrow}$ Lower altitude (Mountain top) (Sea level) Which of the match above is/are correct?
Explanation
Biodiversity in not uniform throughout the world because it is affected by many factors Barring arid/semiarid and aquatic habitats, biodiversity shows latitudinal and altitudinal gradients. Biodiversity is low at the poles. It increases in temperate areas but reaches the maximum in tropics. Biodiversity increases from poles to equator, i.e., from high to low latitude and vice-versa Biodiversity increases from higher altitude to lower altitude that is from mountain top to sea level and vice-versa A decrease in species diversity occurs as we ascend a high mountain due to drop in temperature (lapse temperature being $6.5℃$ for 1 km or 1000 m) and greater seasonal variability
