NCERT Solutions for Class 6 Science Chapter 9 – The Living Organisms and Their Surroundings
9.1 Organisms and the surroundings where they live
There are different landscapes and terrains on Earth. Many living organisms have made these terrains as their home. Creatures that live on these lands are called organisms. A surprising fact is that the opening of a volcano is also home to multiple organisms. The house you live in may contain many living organisms. The places in which animals live is called habitat. Living organisms depend on these habitats for their food, air, water, shelter, etc.
9.2 Habitat and Adaptation
You will get an idea about the habitat in the first chapter, but what do we understand by adaptation? Plants and animals keep changing to adjust to the surroundings they live in. This helps them to survive in their habitat. This is called adaptation. You can observe this on your own. The next time you go out, take a look at plants and animals in different regions. You can notice a change in them at different places.
Think about the plants and animals that live under the water in the sea, ocean,rivers, lakes etc. They use dissolved air in the water to breathe. Plants and animals in deserts live accordingly to breathe air from their surroundings.
9.3 A Journey Through Different Habitats
Desserts – Due to lack of water, the leaves of plants in the desert shrink to spines. This prevents the loss of water during transpiration. Rats and snakes live in burrows to protect themselves from the outside heat and only come out in the evenings.
Mountains – In this region, the trees are cone shaped and have thorns on them to prevent the accumulation of snow and rainwater. Animals that live in this region have thick fur, which protects them from the cold weather.
Grasslands – Plants in this region are lush green during the rainy season and turn pale and brown during the dry season. Animals live here according to the changing seasons and hence these areas are regarded as one of the most productive landscapes.
Aquatic/marine habitats – Marine habitats support aquatic life – Living organisms that live in the water and have gills in their bodies. These organisms adapt themselves to live underwater.
Fresh Water – Living organisms that cannot live in salty water, make freshwater as their home. These include ponds, lakes, and rivers, etc.
9.4 Living Things Around Us
The earth has both living organisms and nonliving things. Living organisms perform several functions to survive like moving, breathing, reproducing, consume food and water to grow, whereas non-living things cannot perform these functions.
As living things are made up of cells and tissues, they are subject to change and growth. The cells and tissues continue to grow in numbers and different. The mechanism of respiration might change depending on the adaptation.
Living cells change themselves according to situations. Hence living cells respond to stimuli. Stimuli help living organisms to adapt according to changing surroundings. Every living organism has a reproductive system. Living organisms have cells and tissues, which grow and reproduce new ones of their kind which increases the number of living organisms in their region.
All living organisms consume food to grow. The digestive system converts the food we eat into the simplest form, once all the nutrients have been absorbed, the organisms get rid of the waste through excretion. In plants, excretion is known as secretion.
Not all living things can move. Plants, bushes, and trees don’t move around as they are anchored to the ground through roots and prepare their own food through photosynthesis.
However, animals, being heterotrophs, have to move around in search of their food.
