(5aiii)
Reseeding can be defined as the practice of cultivating the land or raising stock

(5aiv)
Stocking rate is the basic relationship between livestock and the forage resource.

(5av)
Natural pasture is usually on land unsuited to arable cropping because of stoniness, seasonal waterlogging, slope or a short growing season, or due to pattern of rainfall distribution or temperature.

(5b)
(i) Climatic Factors
(ii) Soil or Edaphic factors
(iii) Biotic Factors
(iv) Topography
(iv) Size and shape

(5c)
(i) Weeds Add Organic Matter and Nutrients to the Soil
(ii) Weeds Check Wind, Water and Soil Erosion
(iii) Some of the Weeds are used as Fodder for Animal
(iv) Some of the Weeds are used as Leafy Vegetables
(v) Some of the Weeds have Medicinal Value

(ii)rabbits

(3bi)

(4aiii)
(i) Caecum
(ii) Bladder

(4b)
(i) Caecum: Absorbs fluids and salts that remain after completion of intestinal digestion and absorption

(ii) Gizzard: Aids in digestion by particle size reduction, chemical degradation of nutrients and regulation of feed flow, and responds rapidly to changes in the coarseness of the diet.

(iii) Crop: It is used to store food temporarily before moving it on to the stomach.

(iv) Rumen: It stores food that a ruminant regurgitates, chews again and swallows a second time.

(v) Lung: Its function is to deliver oxygen to the blood stream in exchange for carbon dioxide
