class 6 THE LIVING ORGANISMS — CHARACTERISTICS AND HABITATS

The document discusses adaptations of organisms to various habitats. It describes how cacti, camels, and desert rats are adapted to desert habitats through reduced water loss and moisture retention adaptations. Plants in mountain habitats have adaptations like cone shapes, needle-like leaves, and long hair to withstand cold and snow. Polar animals like polar bears have thick fur, white coloration, and padded feet for surviving in icy polar regions. Forest animals rely on camouflage while grassland animals like lions have traits for hunting prey. Aquatic animals are adapted for life in water through streamlined bodies, gills, fins, and other traits.

Adaptations of organisms Class 6 By Shweta Deveshwar
Terrestrial Habitat
Desert habitat • Dry and hot conditions • Very little rainfall. • Shortage of water • Sand and soil is dry and hot. • Hot during day and cold at night.
Cactus • Leaves reduced to spines. • Stem is green to carry photosynthesis. • Stem covered with thick waxy layer of cuticle . • Fleshy stem store water • Few and sunken stomata.
Adaptations needed • Reduce water loss • Retain moisture in body
Camel Fat stored in hump padded feet to walk on hot sand Long legs to keep body away from heat of sand
Camel Long eyelashes Closing nostrils
Desert rat • Hops like a Kangaroo to protect themselves from predators. Long hind legs Short upper legs
Desert rat • Lives in deep burrow • Nocturnal • Excrete concentrated urine and dry faeces.
Mountain habitat • Cold and windy place. • Snow fall during winters.
Adaptations in plants • Cone shaped trees with sloping branches. • It helps rainfall and snow slide easily.
Adaptations in plants • Needle like leaves • Gives conical shape to plant • Helps in shedding the snow from leaves
Yak • Body covered with thick long hair to give warmth to body.
Mountain goat • Thick long hair that protect it from cold. Thick strong hooves
Polar habitat • Extremely cold climate • Covered with snow for most of the year.
Polar Bear and Snow Leopard • Thick fur on body to give warmth. • White skin to hide in snow • Thick padded feet to walk on snow.
Hibernation • Winter sleep of animals or physiological inactive state to conserve energy.
Forest habitat • Densely growing trees, thick shrubs and tall grasses. • Generally has warm and humid climate.
Grassland habitat • Has short and tall grasses. • Scattered small and large trees. • May have hot summer to severe winter.
Lion • Strong claws to capture and hold the prey. • Claws can be folded so that the don’t make any noise while walking.
Lion • Eyes in front helps locating the prey accurately • Light brown in colour help to hide in grasses. • Strong pointed teeth to tear flesh
Deer • Eyes on two sides of its head which allow it to look in all directions for danger. • Long ears to hear even faint movements. • Strong legs to run fast. • Strong flat teeth to chew hard plant stem.
Aquatic habitat (habitat in water) Ocean habitat Fresh water habitat (Pond and lake)
Fish • Streamlined body • Paired flat fins. • Gills for respiration • Scales on body to protect body from water.
Dolphins • Have lungs and nostrils • Blowholes present at the upper part of the head. • Can stay under water for a long time.
Frog • Can live both on land and water. • Webbed feet helps to swim in water. • Strong back leg helps in leaping and catching prey. • Lungs to respire on land, moist
