What kind of impact does loss of biodiversity have on the ecosystem?

a. Decline in plant production
b. Lowered resistance to environmental perturbations
c. Increased variability in ecosystem processes like plant productivity, water use, and pest and disease cycles

Loss of biodiversity in a region may lead to:

• decline in plant production,
• lowered resistance to environmental perturbations such as drought,
• increased variability in certain ecosystem processes such as plant productivity, water use, and pest and disease cycles.

Ecologists warn that if the present trends continue, nearly half of all the species on earth might be wiped out within the next 100 years.
