D.Answer the following questions:-
Q.1. Why do organisms need to take food?

Ans. Food is needed by all organisms for many purposes:

(a) The main function of food is to help in growth.

(b) Food provides energy for movements such as running, walking or raising our arm.

(c) Food is also needed for replacement and repairing damaged parts of body.

(d) Food gives us resistance to fight against diseases and protects us from infections

 

Q.2 Where is the bile produced? Which component of the food does it help to digest?

Ans. Bile is produced in liver. The bile juice stored in sac called the gall bladder. It helps in the digestion of fats.


Q.3:Explain how soil is formed.
Ans. Soil is formed through the process of weathering. Weathering is a process of physical breakdown and chemical decomposition of rocks and minerals near or at the surface of the earth. This physical and chemical decomposition is primarily done by wind, water, and climate. As a result of these processes, large rock pieces are converted into smaller pieces and eventually to soil.

Q.4:Name the elements that determine the weather of a place.
Ans.The elements that determine the weather of a place are temperature, humidity, rainfall, and wind speed.

Q.5 :When are the maximum and minimum temperatures likely to occur during the day?
Ans.The maximum temperature of the day occurs in the afternoon while the minimum temperature occurs early in the morning.
