Agric

Q1a.

I) unpredictable climate

1. Droughts or prolong periods without rain results in poor yields

2. Flooding results in erosion 

3. Inadequate sunshine also reduces photosynthetic ability of plants

ii) inadequate rural infrastructure

1. This results in urban drift ie massive exodus to big cities for better standard of living.

2. Results to massive reduction in agricultural work force in rural settings

3. Results in low agricultural production

iii) Diseases

1. Result in increase in agricultural cost of production

2. Reduce the quality of farm produce

3. Reduce farmers income

Q1bi)

1. Contour ditch  2. Border dyke 3. Furrow irrigation  4. Wild flooding

5ai) -Beak/Mouth

-Esophagus

-Crop

-Proventriculus

-Small Intestine

5aii) -Beak/Mouth: The Beak/Mouth contains glands that secrete saliva, which wets the feed to make it easier to swallow. Also, the saliva contains enzymes, such as amylase, that start the digestion process.

-Esophagus: The esophagus is a flexible tube that connects the mouth with the rest of the digestive tract. It carries food from the mouth to the crop and from the crop to the proventriculus.

-Crop: The crop is an out-pocketing of the esophagus and is located just outside the body cavity in the neck region. Swallowed feed and water are stored in the crop until they are p

-Proventriculus: The esophagus continues past the crop, connecting the crop to the proventriculus. The proventriculus (also known as the true stomach) is the glandular stomach where digestion primarily begins.

-Small Intestine:The small intestine is made up of the duodenum (also referred to as the duodenal loop) and the lower small intestine. The remainder of the digestion occurs in the duodenum, and the released nutrients are absorbed mainly in the lower small intestine
