Solution:

Cyanobacteria is a photosynthetic-bacteria which forms symbiotic relationship with plants and fixes nitrogen. It is useful as biofertilizer.
Bacillus thuringensis is a bacteria having the capacity to produce an insecticidal protein called bt toxin. It has application as bioinsecticide/biopesticide.
Mycorrhizae is a mutual relationship between fungi and plant. Both benefit from each other. In it, the fungus colonises the root system of the host plant either intra- or extra- cellularly. The fungal group is known to absorb phosphorus from soil and pass it to the host plant.
Microbes are used a direct source of food as they are rich in protein. Single cell protein denotes dead and dried cells of microbes where each cell is like a source of protein. Chlorella, a type of algae is used as SCP
