Solution

The correct option is A I and II
Biodiversity refers to the variety and variability that is seen at different levels of biological organisation.

Biodiversity loss primarily occurs due to human interventions which lead to habitat destruction or fragmentation, over-exploitation of certain species, alien species invasion, etc.

The general effects of biodiversity loss can be listed as -
  • Decrease in plant production
  • Lowered resistance to environmental perturbations such as drought. Environmental perturbations are temporary, rapid changes in environmental conditions that cause a major change in an ecosystem.
  • Increased variability in some ecosystem processes such as productivity of plants.
