The food web (in contrast to the food chain) means that there may be more than one organisms competing for the same prey or food or they may be one organism that preys on many kinds of food etc. It is more complex than the food chain. If the food source of a certain animal was added to the food web, meaning there will be other organisms competing for that food source, then the population of that certain animal will either decrease (if the animal is not fit for the competition of food), or become constant or even rise (if the animal is well suited for the competition).

Thus, the correct answer is option (e).
the organisms in the order Gymnophiona have no limbs. Option 3
<h3>What is Gymnophiona ?</h3>
Gymnophiona also called Apoda, area known as one of the three major orders of the class Amphibia.
Its members are known as caecilians which means “sightless” or “blind.”
Majority of the organisms in this group are limbless and wormlike amphibians that live underground in humid tropical regions throughout the world.
They are believed to have internal fertilization.
Their heads are blunt, and their skulls are bony and compact in nature.
Since they are limbless, they have no limbs
Thus, the organisms in the order Gymnophiona have no limbs. Option 3
