(a) Primary source of specimens J and L

Both specimen J (saw dust) and specimen L (charcoal) are obtained from wood/timber, that is, forest trees. Saw dust is the waste produced when timber is sawn, while charcoal is produced by the controlled burning of wood.

(b) Uses of the specimens

Four uses of specimen J (saw dust):

• For making particle boards and ceiling boards.
• As a source of fuel and for smoking fish.
• As litter/bedding material in poultry and animal houses.
• As mulch and organic matter, and as a planting medium in seed boxes.

Four uses of specimen K (piece of plank):

• For constructing farm buildings and structures such as pens, cribs and hutches.
• For making farm furniture.
• For making handles of farm tools such as knives, cutlasses and dibbers.
• For packaging agricultural produce and for making crates and boxes (also as fuel and for paper production).

Two uses of specimen M (honey):

• As food and a natural sweetener.
• For medicinal purposes and in the production of cosmetics and pharmaceuticals.

(c) Three ways of ensuring continuous supply of the primary source of specimen K (timber/forest trees)

• Planting seedlings of suitable, fast-growing forest tree species (afforestation and reforestation).
• Practising selective and controlled felling instead of clear felling, and encouraging regeneration of stumps.
• Enforcing forestry regulations, protecting forest reserves and preventing bush burning.
