    Camel is an animal that lives in hot desert where water is scarce. Its body structure helps it to survive in desert conditions. The special features which help the camel to survive in desert are:

    1. It has long legs which help to keep its body away from the hot sand in the desert.
    2. It can drink a large amount of water and store it in the body.
    3. It is adapted to save water in the dry desert by passing a small amount of urine, excreting dry dung and do not sweat at all.
    4. A camel’s hump has fat stored in it so it can break down stored fat to obtain water during emergency conditions.
    5. It has large and flat feet which help it to walk easily on soft sand.

    Solubility of the substance is the maximum amount of solute that can be dissolved in specific amount of solvent.
    if the process is exothermic in nature then the solubility of the substance decreases with rise in temperature.
    but if the process is endothermic in nature the solubility of substance increases with increase in temperature

    Clouds are formed by the process of evaporation and condensation
    Water evaporates from water bodies and rises up in the air. This air also gets heated.
    Hot air carrying water vapour rises up. It cools down as it goes up.
    Cooling causes condensation of water vapour, which leads to the formation of tiny droplets.
    Tiny droplets grow bigger and heavy by more condensation which ultimately leads to the formation of clouds.

    The image from a plane mirror has the following characteristics: i. It is erect. ii. It is virtual. iii. It is of the same size as the object. iv. There is a parity change i.e. the image flips about a vertical line. v. Its distance from the mirror is the same as that of the object. If the object moves towards (or away from) the mirror at a certain rate, the image also moves towards (or away from) the mirror at the same rate.

    Differentiating Property

    Physical Change

    Chemical Change

    1

    Explanation

    In a physical change, the molecules are rearranged while their actual composition remains same.

    In a chemical change, the molecular composition of a substance completely changes and a new substance is formed.

    2

    Example

    Some example of physical change are freezing of water, melting of wax, boiling of water, etc.

    A few examples of chemical change are digestion of food, burning of coal, rusting, etc.

    3

    Reversibility

    Physical change is easily reversible i.e original substance can be recovered.

    Chemical change is irreversible i.e. original substance cannot be recovered.

    4

    Formation of new substance

    In physical change, no new substance is formed.

    A chemical change is always accompanied by one or more new substance(s).

     The Nitrogen Cycle: The continuous process by which nitrogen is exchanged between organisms and the environment is called nitrogen cycle. Nitrogen is an essential nutrient, needed to make amino acids and other important organic compounds, but most organisms cannot use free nitrogen, which is abundant as a gas in the atmosphere. Nitrogen cycle involves the following steps: (i) Nitrogen fixation: This process involves the conversion of atmospheric nitrogen into nitrates, which are soluble in water. This is done by various nitrogen fixing bacteria. Example - Rhizobium, blue green algae and bacterium Azotobacter. (ii) Ammonification: It is the process of decomposing complex, dead organic matter into ammonia. This is done by microorganisms living in the soil. (iii) Nitrification: It is the process of conversion of ammonia into nitrites and then into nitrates. This is done by nitrifying bacteria. Example - Nitrosomonas and Nitrobacter. (iv) Denitrification: It is the process of reducing nitrates present in the soil to release nitrogen back into the atmosphere. Example - Pseudomonas.

    The decomposers help in decomposing the dead bodies of plants and animals, and hence act as cleansing agents of environment. The decomposers also help in putting back the various elements of which the dead plants and animals were made, back into the soil, air and water for reuse by the producers like crop-plants, e.g. the decomposers like purifying bacteria and fungi decompose the dead plants and animal bodies into ammonia. This ammonia is converted into nitrates by nitrifying bacteria present in soil. These nitrates act as fertilizer in the soil and are again absorbed by the plants for their growth. Thus, the nitrates act as fertilizer in the biosphere so that the process of life may go on and on like an unending chain.
