Dairy farming is the business of breeding, raising, and managing dairy animals (like cows and buffaloes) for the production of milk and milk products. Poultry farming involves the commercial raising of domesticated birds (like chickens, ducks, and turkeys) for the production of meat and eggs.

Hydrophytes live in water, mesophytes in moderate conditions, halophytes in saline soils. Xerophytes minimize transpiration and maximize water uptake.
