Summary of NCERT Class 6 Science Chapter 6

CBSE Class 6 Science Chapter 6 introduces you to the definition of organisms and their characteristics. It also explains the concept of surroundings and habitat. In addition, this chapter also deals with the idea of biotic and abiotic components along with the process of adaptation. 

For better understanding, let us now dive into the summary of NCERT Class 6 Science Chapter 6.

Organism

Any living entity, from tiny bacteria to enormous elephants and everything in between, is simply referred to as an organism. There are various kinds of flora and animals in various places. For instance, 

  • Deserts include cacti and camels as vegetation. 
  • Crabs and palm trees can be seen on beaches. 
  • The sea is home to fish and other aquatic creatures.

Characteristics of Living Organisms

  • Nutrition: It is the process through which animals receive food and use it for all of their activities. Each organism needs nutrition to gain energy.
  • Growth: Every living being grows and shows growth in diverse ways. Its body cells divide and grow to facilitate growth in an organism.
  • Respiration: It is the process of inhaling and exhaling in a living organism. All living things require breathing to survive. The body finally gets energy from the food it consumes through breathing. Different methods for the exchange of gases, a step in the respiration process, may exist in some animals.
  • Excretion: Every living creature needs nourishment. Not all of the food consumed is really utilised. It is only partially used by the body. Food that is leftover or unfinished becomes waste and must be eliminated. In other bodily functions, our bodies also create wastes like urea. All of this waste material is eliminated by living things through a process called excretion.
  • Reproduction: It is the process by which all living things create new members of their own species. Distinct plants and animals may have distinct reproductive methods. Some creatures lay eggs to hatch their young. Young are born to some animals. The seeds that are produced by plants grow into new plants. Other than seeds, certain plants can also reproduce by other organs.
  • Response to Stimuli: Stimuli are changes in our environment that cause us to react to them. Every living thing responds to changes in its environment.
  • Movement: Animals move around and display a variety of different body movements. In order to prevent movement from one location to another, plants are typically anchored in the soil. However, different elements like water, minerals, and the food that plants synthesize migrate from one area to another. Other types of movement are also displayed by plants, such as the opening and shutting of flower buds.

Habitat and its Types

The habitat is the environment in which living things thrive. It serves as the organisms’ primary source of food, water, air, shelter, and other necessities. Also, it refers to a place to live (a house).

  • Terrestrial Habitat: The living spaces of animals and plants living on land are termed terrestrial habitats. Common examples are mountain ranges, forests, deserts, grasslands, and coastal regions.
  • Aquatic Habitat: The ecosystem of animals and plants living on the water is known as an aquatic habitat.

Important Definitions in NCERT Class 6 Science Chapter 6

Adaptation

Having particular traits or behaviours that allow an animal or plant to survive in its environment is referred to as adaptation. Diverse animals have different ways of adapting to their environment. For instance, a fish has slick scales all over its body. These scales let the fish travel through the water easily while also providing protection.

Biotic Components

Living components in a habitat are termed biotic components. Common examples include animals and plants.

Abiotic Components

Non-living components in a habitat are known as abiotic components. Rocks water, air, and soil are examples of abiotic components.
