Question

How many kinds of aquatic habitat are there? Explain them.

Answer 1

Aquatic habitats are mainly of three kinds:

(a) Freshwater habitat: Rivers, lakes, ponds and streams are examples of freshwater habitat. Fish, frogs, ducks, lotus and water lilies are found in fresh water.
(b) Marine habitat: Oceans and seas form the marine habitat. A large variety of sea animals such as whale, fish, crab, jellyfish, sea turtle and seaweed are found in marine habitat.
(c) Coastal habitat: Coastal habitat refers to the region where land meets the sea. It is of the following types:

• Estuaries: These are the regions where saltwater mixes with freshwater. Animals found here are crabs, oysters, waterfowl and worms. Mangroves and marsh grasses are some of the plants found here.
• Coral reefs: These are rock-like structures made from the calcium carbonate secreted by corals. Besides corals, sea anemones, starfish and octopuses, a variety of fish are found in coral reefs.
