In Malacophilous plants, flowers are pollinated by snails and slugs. Example, some water plants such as Lemna and members of Poaceae.

In Ornithophilous plants, flowers are pollinated by means of birds. Example, Begonia is pollinated by the hummingbird.

In Chiropterophilous plants, flowers are pollinated by bats. Example, Adansonia (baobab tree).

In Anemophilous plants, flowers are pollinated by wind. Example, Maize, grasses etc.

So, the correct answer is C.

Hovering birds are the hummingbirds that are the most common flower-visiting birds and are attracted to bright colored flowers that produce nectar. These birds have a long beak and they do not sit on the flower, they hover over it. The flowers of such plants hang (are pendent) so that birds can hover over it and insert the beak in the flower. This type of pollination by means of birds is called ornithophily. The example is which is pollinated by hummingbirds, i.e. Bignonia.

So, the correct answer is A.

Pollination by humans can occur mechanically only .

Pollination which occurs by means of birds is called Ornithophily.

Pollination which occurs by means of bats is called Cheiropterophily.

So, the correct answer is C.

Pollination of flowers which occurs by means of bats is called Chiropterophily. Example of plant pollinated by a bat is Kigelia (also known as sausage tree) which is pollinated by the bat Micropterus. Salvia has a turnpipe mechanism of pollination and is pollinated by bee. Ophrys is pollinated by a moth Colpa aurea (hairy wasp) and they both possess a relationship of pseudocopulation.

So, the correct answer is C.

• Mulberry is pollinated by wind.

• Cucumber is pollinated by bees.

• Maize is pollinated by wind.

• Vallisneria is pollinated by water.

Hence, animal vector is required for the pollination of Cucumber. So, the correct answer is B.

Eight species of birds were observed in contact with open flowers on focal

agaves; of these, rufous hummingbirds were most common. Two additional species, Zenaida asiatica (white-winged dove) and Corvus sp. (one of three species of ravens and crows potentially present in the study area), were observed at open flowers on non-focal plants.

So the correct option is 'Agave'.
