NEET BIOLOGY

Detailed explanation-1: -Species richness generally increase toward the poles. An ecosystem is considered stable if it is both resistant and resilient. At the international level, the United Nations has facilitated several treaties to promote biodiversity. Most scientists agree that cloning provides much help to prevent biodiversity loss.

Detailed explanation-2: -Species diversity is higher at the equator than at the poles. In biological terms, this is referred to as the latitudinal diversity gradient (LDG), in which the number of species increases from the poles to the Equator. This ranks among the broadest and most notable biodiversity patterns on Earth.

Detailed explanation-3: -Species richness increases in response to increasing tide range, increasing wave energy, decreasing sand particle size and in flatter and wider beaches. This means that macrofaunal species richness increases as beaches become more dissipative (McLachlan and Dorvlo, 2005).

Detailed explanation-4: -The tropical region has a stable environment. It receives enough rainfall and sunlight. The climate encourages the wealth of animals and finding their niche in the ecosystem. Therefore, the less stable climatic condition of the poles is the primary reason for less species diversity.

Detailed explanation-5: -Species diversity decreases as we move from the equator to the poles. Tropics have more diverse species compared to the temperate regions or polar regions.
