Consider the following kinds of organism: 1. Bacteria 2. Fungi 3. Flowering plants Some species of which of the above kinds of organisms are employed as biopesticides?

Biopesticides are derived from natural materials such as animals, plants, bacteria, and certain minerals. Bacteria are widely used, with Bacillus thuringiensis (Bt) being the most prominent example; it produces proteins that are toxic to specific insect larvae. Fungi also serve as effective biopesticides; for instance, Beauveria bassiana is an entomopathogenic fungus used to control various pests like thrips and whiteflies, while Trichoderma species are used to manage soil-borne pathogens [2]. Flowering plants are a major source of botanical pesticides. The neem tree (Azadirachta indica), a flowering plant, produces azadirachtin, which disrupts the growth and feeding of insects. Other examples include pyrethrins from chrysanthemums and rotenone from legume roots. Since species from all three categories—bacteria, fungi, and flowering plants—are actively employed as biopesticides, all three statements are correct.
