Yes, the agriculture and animal husbandry are the two sides of the coin. The cattle will help the farmer in various agricultural works and the by products of agriculture can be used as food for the cattle.

Question 13.
How do you appreciate the uses of cattle?
Answer:
A. Uses of cattles :
1. The term cattle represents both cows, bulls and also buffaloes. Another term that is used to represent these is Livestock.

2. Cattle were domesticated primarily for food, for milk and meat. However, later they were used in agricultural operations, for transporting loads from place to place and their skins were used for making leather goods. Buffaloes are now reared for milk and their skin is used for making leather goods.

3. The use of cattle for agricultural operations is more prevalent in Asian countries. In Western countries, the meat from cattle – called Beef is more popular and special breeds of cattle are grown for this purpose. Milk yield from these animals is usually low when compared with dairy breeds of cows. Modern dairy cow is a good example for the efforts made by man to increase the food production.

4. The cow dung, its urine are useful as organic manure.

5. Biogas is another advantage of cattle dung.

• Queen bee: Only one per bee hive. It can lay 1200 eggs per day and live up to three years.
  It controls workers through ‘pheromones’. This division of labour among then makes one amazing.

Question 15.
Conversion of agricultural lands into fish ponds leads to food crisis and environmental pollution. Write your opinion to participate in debate on this issue.
Answer:
The fast conversion of agricultural fields into fish ponds in many villages worried the administration, because the fish ponds cause damage to the underground water source. To make the fish pond we remove the top layers, and use fertile layers of the soil. If the disposal of waste generated in aquaculture is not properly planned, it further causes pollution.

Advantages:

• The farmers who get very low income from their agriculture can convert their lands into fish ponds which is a good source of income.
• The unusual changes in the climatic conditions may not affect to a greater extent.
• Good marketing facilities and transportation is available for marine products.

Disadvantages : Available crop land area decreases. Food production decreases. Terrestrial flora and fauna depletes.

Question 16.

Answer:
Rearing of livestock and poulty industry are parts of agriculture in our country. People grow cows, buffaloes, goat, sheep, pigs and hen. They arrange the grass lands for grazing by cattle. The cattle dung and urine are used as bio- manure in the crop field.

Farmers allow their cattle or goat or sheep to graze in their fields. Animals get food for them and then excrete wastes in the field, which are further useful in increasing field fertility. Bullocks and oxen are used for transporting the goods. The rearing of live stock helps giving financial support with the byproducts.

Question 6.
In which season do you find rearing of honey beehives. Write the process of extracting honey from the hive.
