Complete question: While taking a walk in a park, Muskaan observed an insect on a pitcher plant (Nepenthes). Immediately the flower opened up and the insect slid down. To which of the following categories does the pitcher plant belongs?
a) Saprophytes
b) Insectivorous
c) Parasite
d) Symbiotic
Answer:
The correct answer is option b. Insectivorous
Explanation:
A carnivorous or insectivorous plant is the one that obtains most of its nutritional necessities from the capture and consumption of protozoans or animals, especially insects and arthropods.
These insectivorous plants grow in poorly nutritional soil, so they need to get nutrients from their prey. These species attract and trap their prey, and by the action of specific enzymes and digestive bacterias, they can absorb the insects' nutrients.
These insectivorous plants make use of their flowers to trap the prey. These tramp flowers are cup-shaped, and at the bottom of this cup, there is a liquid where insects get trapped and die.
Insects are attracted by aromas produced by the edges of the trap and when they land, they slip and fall inside, and once drowned, the enzymes digest them.

I remember doing a question like this in class while learning about natural selection. The 2 colorations of moth live in a habitat that originally supported the lighter variant due to the light-colored trees. When the industrial revolution began, the soot levels reversed this because the black moths were more camouflaged that the lighter ones. A way we could prove this was the amount of black dresses and dark colored clothing during the time, often due to the fact that lighter colored clothing would turn black by the time the wearer arrived home. The lighter colored moths simply died off a bit because of this.
I believe it is Wegener's theory did not explain how the continents could move.
Answer:
Limpets
Explanation:
Since the arrows represent flow of energy, and there is no path of energy from fish to limpets, limpets won't be affected at all.
Continual questioning of observations.
