NEET Biology question
Choose the correct combination from the given statements regarding gradients of biodiversity: I. Biodiversity increases from the equator (lower latitude) to the poles (higher latitude). II. Biodiversity remains constant across different altitudes, from sea level to a mountain top. III. Biodiversity decreases from sea level (lower altitude) to a mountain top (higher altitude). IV. Biodiversity decreases from the equator (lower latitude) to the poles (higher latitude). Which of the above statements is/are correct?
Solution
Biodiversity decreases as one moves from the equator (lower latitude) towards the poles (higher latitude), making statement IV correct and statement I (which claims the opposite direction) incorrect. Along an altitudinal gradient, biodiversity similarly
