6a)are large areas of land where plants either growing naturally

or planted are specially preserved by government for specific

purposes. 6bi)1-increased standard of living. 2- accessibility to

forest products


6bii)1-weed control. 2-reduced cost of established plantation.

6e)1-dura. 2-pisifera & tenera. 6d)1-helps to conserve moisture &

prevent evaporation from soil. 2-it reduces rapid soil temperature

fluctuation

4a)1-climate. 2-temperature. 3-rainfall. 4-wind. 4bi)1-cultivation

of food crops. 2-rearing of animal. 2bii)construction purposes. 2

-residential building

4c)nitrogen(function: 1-promotes vegetative & short system growth.

2-aids plants growth & reproduction.  symptoms:1- stunted growth.

2-yellowing of leaves)

4c)potassium(functions:1-aids synthesis of carbohydrate. 2-

promotes development of young plants. symptoms:1-weak slender

stems. 2-delayed growth). 4d.1-support d growth of  crops. 2-

determines d level of fertility of d soil.



5a)1-provision of food. 2-provision of timber. 3-provision of

employment. 4-provision of raw material for industry.
