(1c)
A ration is the quantity of feed given to an animal within a period of twenty-four hours to meet its nutritional requirements.

(1d)
(i) Destruction of soil microorganisms: Bush burning kills beneficial organisms such as bacteria, fungi, and earthworms that improve soil fertility.
(ii) Loss of soil nutrients: Essential nutrients, especially nitrogen and organic matter, are destroyed or lost during burning.
(iii) Exposure of the soil to erosion: The removal of vegetation cover leaves the soil bare and susceptible to wind and water erosion.
(iv) Destruction of crops and wildlife: Bush burning may destroy growing crops, beneficial insects, and small animals living on the farmland.
(v) Reduction in soil fertility: Continuous bush burning lowers the organic matter content of the soil, thereby reducing its productivity.

(7a)
=Based on habitat=
(i) Freshwater fish.
(ii) Marine (saltwater) fish.

=Based on morphology (body structure)=
