Answer : 4. "Insect"
Explanation :
Fragrant flowers attract pollinators like bees, butterflies, and birds with their pleasant scent. These pollinators visit the flowers to feed on nectar or collect pollen. During their visits, they unintentionally transfer pollen from one flower to another, facilitating pollination. This process enables the plant to reproduce and produce seeds. Different plants rely on specific pollinators, ensuring their reproductive success and genetic diversity within the ecosystem.

Answer : 3. "tentacles"
Explanation :
Actually, the locomotor part of a hydra is not its tentacles. Hydras move by a remarkable way called "looping." They attach one end of their body to a surface and then release the other end, allowing it to move and attach again. This looping movement is facilitated by the contraction and expansion of the body, rather than the use of tentacles. Tentacles are specialized structures primarily used for feeding and defense in hydras.
