This document discusses aquatic habitats. It defines habitat and describes the two types of aquatic habitats: saltwater and freshwater. Saltwater habitats include oceans and seas, and the process of obtaining salt from saline water is described. Freshwater habitats include lakes, rivers, and ponds. The document also discusses hydrophytes (aquatic plants) and hydrocoles (aquatic animals), providing examples of each. Finally, it outlines some adaptations of common hydrocoles like fish, frogs, and dolphins that allow them to survive in aquatic environments.

3.  A habitat is an ecological or environmental area
that is inhabited by a particular species of
animal, plant, or other type of organism. It is
the natural environment in which an organism
lives, or the physical environment that surrounds
a species population.
 A habitat is made up of physical factors such as
soil, moisture, range of temperature, and
availability of light as well as biotic factors such
as the availability of food and the presence of
predators. A habitat is not necessarily a
geographic area—for a parasitic organism it is
the body of its host or even a cell within the
host's body

4. AQUATIC HABITAT
 Aquatic habitat is something that is related to
WATER.
 As it’s name itself describes it – AQATIC means
WATER
 In an Aquatic Habitat, we can find animals as well as
plants.
 There are two types of water bodies on Earth– FRESH
WATER BODIES and SALT – WATER BODIES.

5.  It is also called SALINE WATER, and BRINE
WATER.
 It mainly consists of oceans and seas.
 They are mainly composed of water, salt and
some impurities.
 It is not fit for DRINKING, AGRICULTURE,
COOKING FOOD etc.
 SALINE WATER can be used to obtain salt.

6. PROCESS OF OBTAINING SALT
 To obtain salt we must first take out large amount of
saline water from the sea. This can be done by high
tides or can be done in a small part of the sea near
the shore.
 Then it must be kept in the sun so that the water
evaporates and only the salt is left.
 In INDIA, GUJARAT is the largest producer of salt.

7.  FRESH WATER BODY consists of – lakes,
rivers, ponds etc.
 This water is fit for DRINKING,
AGRICULTURE, COOKING etc.
 These are small water bodies and they
finally flow towards the sea or the ocean.
 The longest river on earth is the NILE river.

8. HYDROPHYTES
 HYDROPHYTES are plants which live inside
or on WATER.
 They are also called macrophytes.

9. HYDROPHYTES
• AQUATIC PLANTS
• ALSO CALLED
MACROPHYTES
SUB-MERGED
• HYDRILLA
• COONTAIL
FREE-FLOATING
• LOTUS
• LILY

10.  HYDRILLA

11. HYDROPHYTES
 COON TAIL

12. HYDROCOLES
 HYDROCLOES are the animals which live
underwater.
 EXAMPLES : FISH, FROG, DOLPHIN, STARFISH
etc.

14. ADAPTATIONS
 FISH: fish can breathe through their gills and their
body is streamlined to help them swim against the
water currents.
 FROG: A frog is an amphibian i.e. it can live both on
land and water. It breathes through it’s moist skin
when under water and through it’s nostrils when on
land.
 DOLPHIN: A dolphin is a mammal which lives under
water it does not give eggs and comes out of the
water to breathe.
