Answer: 

• d)
   Eucalyptus

Explanation:

The correct answer is option D, Eucalyptus. Eucalyptus is not an insect-eating plant.

Insect-Eating Plants:
Insect-eating plants, also known as carnivorous plants, are unique types of plants that have adapted to thrive in nutrient-poor environments by capturing and digesting insects or other small organisms. They have evolved various mechanisms to attract, trap, and digest their prey.

Examples of Insect-Eating Plants:
1. Pitcher Plant: The pitcher plant has a modified leaf that forms a pitcher-shaped structure. It attracts insects with nectar and bright colors, and once the insects enter the pitcher, they become trapped in a pool of digestive enzymes and are eventually digested.

2. Sundew: The sundew plant has sticky tentacle-like hairs on its leaves that are covered in a sweet, sticky substance. When an insect lands on the leaf, it becomes stuck to the hairs, and the plant then releases digestive enzymes to break down the insect and absorb its nutrients.

3. Venus Flytrap: The Venus flytrap has specialized leaves with hinged traps. The traps have trigger-like hairs on their inner surface, and when an insect touches these hairs, the trap snaps shut, trapping the insect inside. The plant then secretes digestive enzymes to extract nutrients from the insect.

Eucalyptus:
Eucalyptus is a type of tree that belongs to the Myrtaceae family. It is native to Australia and is known for its fragrant leaves and characteristic bark. Eucalyptus trees are not insect-eating plants. They obtain nutrients through their roots from the soil, like most other plants.

In conclusion, among the given options, the plant that is not an insect-eating plant is Eucalyptus (option D). The Pitcher plant, Sundew, and Venus Flytrap are all examples of insect-eating plants that have adapted unique mechanisms to capture and digest insects for their nutritional needs.
