Why will it be D? It should be C, because the Vaseline blocks the stomata of the leaves, and thus blocks the surface for transpiration, so water droplets will not appear on those leaves, but the uncovered leaves were not stained or covered with anything, so the transpiration process in those leaves should stay normal.

Ans 7:

Class : Class 6
Ans is C because like humans, plants also sweat. This is called transpiration.

It should be option A!

Ans 2:

Class : Class 10
Option B - snake. because golden crowned kinglet is sadly eaten by the snake, so snake is the top consumer

Ans 3:

Class : Class 8
Option B -- Golden Crowned Kinglet gets eaten by the snake so the snake is the top consumer and it should be option B.

Ans 4:

Class : Class 10
should be option A

Ans 5:

Class : Class 9
it should be option A

Ans 6:

Class : Class 9
A substance which constantly gets accumulated in any organism of the food chain gets amplified highest in the topmost predator.This is a rule that can be observed in each and every case of bioamplification in an food web or chain. As the golden crowned kinglet is the topmost predator, option a is correct.
