Manure and fertilizers ale added to the soil of crop field to increase the fertility of soil and productivity of crop. They overcome the deficiency of nutrients in the soil of the field.

Bee hive is made up of wax which is secreted from the wax glands present in the abdomen of worker bees. The hexagonal shape of the cells cover maximum space with minimum use of wax and labour.

The ever increasing human population and the resultant decrease in agricultural land has compelled human beings to move towards animal husbandry to obtain food from animal sources. The last few decades have seen enormous rise in animal meat production and byproducts. Poultry, fisheries, piggery, cattle, sheep and goat farming have developed considerably. Through Operation Flood and the Silver Revolution, milk and egg production have registered a record increase.
Some microorganisms such as nitrogen fixing bacteria, cyanobacteria, fungi and other microflora harbour near the roots of plant inside soil. They convert nitrogen of the air into nitrogenous compounds (ammonia and nitrate) which serve as plant nutrients. Since these microorganisms enrich the soil wiRead more

Since these microorganisms enrich the soil with nutrients and improve soil fertility, hence also collectively known as biofertilisers.
For increasing production. what is common in poultry, fisheries and bee-keeping?
Variety improvement housing, rearing, sanitation, disease control and marketing.
