Explain pollination by animals with examples in detail.
Some animals are also responsible for pollination.
Bees, butterflies, flies, beetles, wasps, ants, moths, birds and (sunbirds and humming birds) and bats are the common pollinating agents.
Among the animals, insects, particularly bees are the dominant biotic pollinating agents. Even larger animals such as some primates (lemurs), arboreal (tree dwelling) rodents, or even reptiles (gecko lizard and garden lizard) have also been reported as pollinators in some species.
Often flowers of animals pollinated plants are specifically adapted for a particular species of animal.
Majority of insect pollinated flowers are large, colourful, fragrant and rich in nectar.
When the flowers are small, a number of flowers are clustered into an inflorescence to make them conspicuous. Animals are attracted to flowers by colour and/or fragrance.
Flowers pollinated by flies and beetles secrete foul odours to attract these animals.
To sustain animal visits, the flowers have to provide rewards to the animals. Nectar and pollen grains are the usual floral rewards to the animals. For harvesting the rewards from the flower the animal visitor comes in contact with the anthers and the stigma. The body of the animal gets a coating of pollen grains.
The flowers pollinated by animals are generally sticky. When the animal carrying pollen on its body comes in contact with the stigma, it brings about pollination.
Which is functionally cross pollination involving pollination agent, but genetically it is simillar to $L$ autogamy?
Which of the following are the important floral rewards to the animal pollinators ?
