Solution
The correct option is C No competition for food
Catla (Catla catla) feeds mainly on tiny animals (zooplankton) but occasionally insect larvae, algae and bits of aquatic weeds are also taken. The shape of its mouth is such that it can feed in the surface layers and hence the fish normally swims in the upper layer of water. Rohu (Labeo rohita) is a mid-water feeder, eating plankton,vegetable matter and debris. Mrigal (Cirrhinus mrigala) is a typical bottom-feeder that picks up large quantities of decaying things along with small animals and plants found in the bottom layers. Because they live in different layers of the pond and eat different things, they can easily be grown together in the same body of water without competing with each other for space or food.
