Which of the following statements is correct?

I. Chiropterophily refers to pollination by bats.

II. Ornithophily refers to pollination by ants.

Statement I is true, but II is false.

The correct answer is (b) Statement I is true, but II is false.

I. Chiropterophily refers to pollination by bats. This statement is true. Chiropterophily is a type of pollination where bats play a crucial role in transferring pollen between flowers. Bats are attracted to certain flowers, often characterized by strong fragrances and night blooming habits. As bats visit these flowers in search of nectar, they inadvertently pick up pollen on their bodies, which they carry and deposit onto other flowers as they move from one plant to another. This process facilitates pollination and is an important mechanism in the reproduction of certain plant species.

II. Ornithophily refers to pollination by ants. This statement is false. Ornithophily actually refers to pollination by birds, not ants. Birds are attracted to specific flowers that provide nectar as a reward. As birds feed on the nectar, they come into contact with the flower's reproductive structures, such as stamens and pistils, and unintentionally transfer pollen from one flower to another, promoting pollination.

Therefore, the correct statement is that chiropterophily refers to pollination by bats, but ornithophily does not refer to pollination by ants.
