Options:

Seed dispersal

Photosynthesis

Oxygen production

Pollination for fruits and seeds

Correct Answer:

Pollination for fruits and seeds

Explanation:

d) Pollination for fruits and seeds

Pollination for fruits and seeds is an example of an ecosystem service provided by nature through pollinators. Pollinators, such as bees, butterflies, birds, bats, and other animals, play a vital role in the reproduction and propagation of flowering plants.

During pollination, these pollinators transfer pollen from the male reproductive organs (anthers) of one flower to the female reproductive organs (stigma) of another flower of the same species. This transfer of pollen leads to fertilization, enabling the formation of seeds and fruits.

Pollination is essential for the reproduction of many plant species, including numerous crop plants that humans rely on for food production. Without pollination, many plants would not be able to produce fruits and seeds, impacting food availability for both wildlife and humans.

As an ecosystem service, pollination contributes significantly to the biodiversity and stability of ecosystems. It also supports agriculture and ensures the availability of a diverse range of fruits, nuts, and other edible plants for human consumption.

In summary, pollination for fruits and seeds is a critical ecosystem service provided by nature through pollinators, which benefits both natural ecosystems and human food production.
