CBSE Class 9 Biology Food Production Worksheet

BIOLOGY

Question I. Given below are five pictures related to Food Production. Provide a title for these pictures in the space provided. State one desirable characteristic or advantage of each of these.
Answer: 1. Title: Crop Production / Intercropping / Mixed Cropping
Desirable characteristic / advantage: Helps in maintaining soil fertility, prevents pest infestation across all plants, and maximizes yield from the same piece of land.
2. Title: Cattle Farming
Desirable characteristic / advantage: Provides milk production and drought labour, and improved breeds offer resistance to diseases and longer lactation periods.
3. Title: Prawn / Marine Fisheries
Desirable characteristic / advantage: Serves as a rich and cheap source of animal protein obtained from water bodies.
4. Title: Poultry Farming
Desirable characteristic / advantage: Provides high-quality eggs and chicken meat with quick economic returns.
5. Title: Composite Fish Culture
Desirable characteristic / advantage: Different species with different food habits are cultured together in a single pond so that they do not compete for food and utilize all available food resources efficiently.
In simple words: The five pictures represent different agricultural and animal husbandry practices that boost food production efficiently.

Exam Tip: Always associate specific advantages like 'no food competition' for composite fish culture and 'milk and draught' for cattle farming.

Make a project on the topic "Role of nutrients in agriculture" in A4 sheet under the following headlines:

1. General introduction
2. Classification of nutrients
3. Significance of nutrients in plant growth.
4. Deficiency diseases caused due to lack of proper nutrients.
5. Supplements of natural nutrients if they are found to be deficient in the soil.
6. Conclusion.
NOTE: Project should be submitted in a handwritten format.

Question II. Given below are outline structures of some 'Bead Necklaces' and a list of characters placed in different categories. Each necklace is given a name that is actually a 'term' important for Food Production. You have to pick one character from each category to list the features of a group. In this way, you will 'string the beads' and the necklace will be complete when all the beads have been allotted characters from each category.
Answer:
1. Cattle Farming Necklace:
- Bead A: For Milk and Drought labour
- Bead B: Dairy and draught animals
- Bead C: Bos indicus and Bos bubalis
- Bead D: Lactation period is important while selecting the right breed
- Bead E: Jersey, Red Sindhi

2. Fish Production / Marine Fisheries Necklace:
- Bead A: Cheap source of animal protein obtained from water
- Bead B: Marine and fresh water varieties
- Bead C: Peneaus monodon
- Bead D: Large schools are located in open sea using satellites and eco-sounders; Capture and culture methods are also used
- Bead E: Mullets and Bhetki

3. Poultry Farming Necklace:
- Bead A: For egg production and chicken meat
- Bead B: Layers and broilers
- Bead C: Fowl
- Bead D: Dwarf parent preferred for commercial chick production
- Bead E: Aseel and Leghorn

4. Bee Keeping (Apiculture) Necklace:
- Bead A: For production Honey
- Bead B: Local and Italia variety
- Bead C: Apis dorsata, Apis mellifera
- Bead D: Value or quality of product depends upon pasturage
- Bead E: Rock bee and little bee
In simple words: Each necklace groups specific biological terms, animals, and management practices related to a major sector of food production.

Exam Tip: Practice linking the correct category features (A to E) to their corresponding agricultural sectors to score full marks in matching questions.
