NEET BIOLOGY

Detailed explanation-1: -Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

Detailed explanation-2: -Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.

Detailed explanation-3: -The current consensus appears to be that, at present, cloning is not a realistic or successful conservation strategy. Perhaps freezing animals’ DNA will give us the option to advance cloning techniques in the future, but conservation efforts to save current endangered animals should not be overlooked.

Detailed explanation-4: -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.
