Which of the following scenarios below best reflects a possible negative consequence of biodiversity loss?

• Human health decreases because of fewer species in an ecosystem.

• The food supply increases because of the introduction of an invasive species.

• Agriculture reduces genetic diversity of plants causing soil nutrition depletion and erosion.

• Growth of medicinal plants will provide clean air, fresh water, medicines and food security.
