Food Supply

Question 1

What is food security and why is it important?

Answer 1

Food security is the ability of human populations to access food of sufficient quality and quantity.

Food security is crucial for ensuring that populations can meet their nutritional needs

Question 2

What drives the demand for increased food production?

Answer 2

Increase in human population and concern for food security.

Question 3

What must food production be to avoid degrading natural resources?

Answer 3

Sustainable.

Sustainable food production ensures the long-term viability of agricultural practices.

Question 4

What factors control agricultural production to maximise crop yields?

Answer 4

Factors that control photosynthesis and plant growth.

Question 5

What are some methods to increase food production?

Answer 5

• Breeding of higher yielding cultivars
• Use of fertiliser
• Protecting crops from pests
• Protecting crops from diseases
• Protecting crops from competition

These methods help enhance crop productivity.

Question 6

Why do livestock produce less food per unit area than crop plants?

Answer 6

Due to loss of energy between trophic levels. limiting livestock productivity.

Question 7

In what type of habitats is livestock production often possible?

Answer 7

Habitats unsuitable for growing crops.

Livestock can be raised in areas where crops cannot thrive.

Question 8

What are some examples of plant crops?

Answer 8

• Cereals
• Potato
• Roots
• Legumes
  These crops are essential for food security.

Question 9

What are the goals of breeders in crop development?

Answer 9

• Higher nutritional values
• Resistance to pests and diseases
• Physical characteristics suited to rearing and harvesting
• Ability to thrive in particular environmental conditions

Breeding aims to improve crop resilience and productivity.
