These comprehensive RBSE Class 6 Science Notes Chapter 9 The Living Organisms and their Surroundings will give a brief overview of all the concepts.

RBSE Class 6 Science Chapter 9 Notes The Living Organisms and their Surroundings

→ The presence of specific features or certain habits, which enables an organism to live naturally in a place is called adaptation.

→ Habitat means a dwelling place (a home).

→ The plants and animals that live on land are said to live in terrestrial habitats. Examples of terrestrial habitats are forests, grasslands, deserts, coastal and mountain regions.

→ The habitats 6f plants and animals that live in water are called aquatic habitats. Examples of aquatic habitats are lakes, rivers and oceans.

→ The organisms, both plants and animals, living in a habitat are its biotic components.

→ The non-living things such as rocks, soil, air and water in the habitat constitute its abiotic components.

→ Desert animals like rats and snakes stay in burrows deep in the sand to avoid intense heat during the day.

→ The leaves in desert plants are either absent, very small er they are in the form of spines. This helps in reducing loss of water from the leaves through transpiration.

→ Trees in mountain regions are normally cone shaped arid have sloping branches. This helps the rainwater and snow to slide off easily. 

→ Animals living in mountain regions have thick skin or fur to protect them from cold.

→ Sea animals have streamlined bodies to help them move easily in water.

→ In some submerged plants, leaves are often highly divided, through which the water can easily flow without damaging them.

→ Breathing is a part of a process called respiration.

→ It is through respiration that the body finally obtains energy from the food it takes.

→ All living things have certain characteristics - they need food, respire, excrete, respond to stimuli, show movement, reproduce, grow and die.
