The document defines different habitats and their components. It describes terrestrial habitat as the land area where plants and animals live, such as forests and grasslands. Aquatic habitat is defined as the water area where plants and animals live, like ponds, lakes, and oceans. It also explains that acclimatization refers to short-term physiological changes an organism undergoes to adjust to its surroundings, unlike long-term genetic adaptations. Finally, it states that the living things in a habitat are its biotic components, while non-living things like rocks, soil, air and water make up its abiotic components.

1. LEARNING GOALS VIDEO : II
• TERRESTRIAL HABITAT
• ACCLIMATISATION
• AQUATIC HABITAT
• BIOTIC AND ABIOTIC
COMPONENTS

2. TERRESTRIAL HABITAT
• The land area where
the plants and animals
live are called
Terrestrial Habitat .
• Few examples are :
Forests , Grasslands ,
Mountain Area ,
Deserts , Coastal
Areas

3. ACCLIMATISATION
• There are some changes that can happen in an organism over a
short period of time to help them adjust in their surroundings .
These small changes that take place in the body of a single
organism over short periods, to overcome small problems due to
changes in the surroundings, are called Acclimatisation.
• These changes are different from the adaptations that take place
over thousands of years.
• E.g During acclimatization over a few days to weeks, the body produces
more red blood cells to counteract the lower oxygen saturation in blood in high
altitudes. Full adaptation to high altitude is achieved when the increase of red
blood cells reaches a plateau and stops.

5. AQUATIC HABITAT
• The water area
where the plants
and Animals live
is called Aquatic
habitat .
• Ponds, swamps,
lakes, rivers and
oceans are some
examples of
aquatic habitats.

6. BIOTIC AND ABIOTIC COMPONENTS
• The living things such as plants and animals, in a habitat, are
called biotic components.
• Various non-living things such as rocks, soil, air and water in the
habitat constitute its abiotic components.

7. SUMMARY
