What are biofertilisers and biocontrol agents? Give one example of each.

Biofertilisers are organisms that enrich the nutrient content of the soil, such as Rhizobium, which fixes nitrogen in the root nodules of legumes, and mycorrhizal fungi, which improve phosphorus uptake. Biocontrol agents are organisms used to control pests and diseases in place of chemicals, such as Bacillus thuringiensis against caterpillars and ladybirds against aphids.

Explanation

Both reduce the need for chemical inputs and the pollution they cause.
