1. Q. What is habitat?   JSUNIL TUTORIL, PUNJABI COLONY SAMASTIPUR    CBSE CLASS FROM 6 th   TO 10+2  Science and Mathematics Ans:  A place where living things   live naturally is known as habitat (Home). For example: (i)Aquatic habitat refers to the water where plants and animals survive like pond, river, sea (in water), (ii)  Terrestrial habitat: It refers to the land where all plants and animals survive. It includes deserts, forests and grasslands, as well as coastal and mountain regions 2. Q.  What are the Components (Parts) of Habitat? Ans: There are two main components of habitat (a) Biotic Components: Living things present in a habitat are called biotic component like plants , animals and micro organism. (b) Abiotic Components: All the non-living things present in a habitat is called abiotic components like air water soil rocks, sunlight and heat etc. 3.Q. How biotic and abiotic components depend on each other? Ans: Biotic and abiotic compo

Separating the Components of a Mixture Importance of separation--> To study and to use the individual components of a mixture Q. What would happen if you were to take a saturated solution at a certain temperature and cool it slowly.  Ans. Different substances in a given solvent have different solubilities at the same temperature. So on cooling substances start to precipitate out. Q. What is suspension?Write its properties? Ans: Suspension:Non-homogeneous systems, in which solids are dispersed in liquids, are called Suspensions so It is a heterogeneous mixture. Properties of a Suspension--- • Suspension is a heterogeneous mixture. • The  particles of  a suspension can be seen by the naked eye. • The particles of a suspension scatter a beam of light passing through it and make its path visible. • The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable. * They can be separated from the mixture by the process of filtration.
