Ans 3: (Master Answer)
The correct answer is A.
Both plants ‘c’ and ‘d’ bear fruits. This means they are flowering plants as only flowers change into fruits. Plant ‘c’ grows in water i.e., it is an aquatic plant but plant ‘d’ does not grow in water thus, it is a nonaquatic plant. Hence 'W' and 'X' represent plant ‘c’ and ‘d’ respectively.

The correct answer is C.
Ram and Achin made the correct statements. Divya made an incorrect statement as the antelope population will be much more than the lion population in order to support the energy needs of the lion population. Ritu also made an incorrect statement because without the grass population, both antelope population and lion population will be negatively affected as lion feeds on antelope and antelope feeds on grass.

The correct answer is A.
When food is taken in the mouth, it is chewed and gets mixed with saliva secreted in the mouth (R). Once swallowed, the food moves through the oesophagus into the stomach where churning and digestion of food with digestive juices occurs (Q). The semi-digested food then moves into the small intestine where complete digestion as well as absorption of nutrients occur (S). From the undigested food, the water is absorbed in the large intestine (P). After this, the undigested food is expelled through the anus in the form of faeces (T).
