Introduction:-
Biotic agents (Types of Pollination):- Biotic agents in pollination are living organisms that play a crucial role in transferring pollen from the male reproductive organs (anthers) to the female reproductive organs (stigmas) of flowers, facilitating fertilization and the production of seeds. These biotic agents include various organisms such as insects (entomophily), birds (ornithophily), bats (chiropterophily), and sometimes other animals like small mammals. These agents are attracted to flowers by various means, including the promise of nectar, pollen, or specific floral traits, and in the process, they transfer pollen, aiding in the reproduction of flowering plants. Biotic pollination often results in a diverse array of plant-pollinator interactions and coevolutionary adaptations.
