LM P2 5a food production

Question 1

what is intensive farming?

Answer 1

Farming that uses little land but has a higher yield and the crops are more closely planted - makes the most use out of the land. To produce to most yield possible at the least expense.

Question 2

an example of intensive farming in animals?

Answer 2

Chickens

Question 3

what do they do to the chickens?

Answer 3

• Keeping them cramped in a small space makes their energy form their food go to biosynthesis (growth) and not muscle contraction, or homeostasis (regulation of their bodies)
  
  • Give them hormones and selectively breeding them helps them to grow faster and bigger
    
    • Antibiotics also prevent them from getting sick before they do, less expensive then treating after.

Question 4

an example of intensive farming in plants?

Answer 4

wheat

Question 5

what do they do to the plants?

Answer 5

• fertilisers
• bio-accumulation
• bio-magnification

Question 6

what does fertiliser do to plants in intensive farming?

Answer 6

Fertilizer helps them grow much faster

Question 7

what do pesticides do to plants in intensive farming?

Answer 7

• Pesticides, chemicals sprayed on the crops that kill pests
  ○ Also kill other insects that help the soil
  ○ Leads to pesticide resistant bugs
  Destroys the food chain in the environment

Question 8

what happens in bio accumulation?

Answer 8

• Bio accumulation, gradual accumulation of substances in tissues and other things in the bodies

Question 9

what happens in bio magnification?

Answer 9

• Bugs eat the chemicals, primary consumer eats, then it carries on in the food chain
  
  • The top predators will then have so much of these toxins

the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.

Question 10

what is hydroponics?

Answer 10

• Systems that allow plants to be grown without soil.

They then take water and nutrients in efficiently Hydroponics

Question 11

what is aeroponics?

Answer 11

is when they are suspended in air, and the roots are sprayed with a fine mist of water and nutrients

Question 12

what is battery farming?

Answer 12

A farm where large numbers of chickens or other animals are kept in very small cages or crowded conditions, they are mostly used for chickens.

Question 13

what is glasshouse farming?

Answer 13

Massive greenhouses that are more technologically advanced

Question 14

advantages of glasshouse farming?

Answer 14

• Traps the heat
  
  • Lets light in
  • Control all factors of photosynthesis
    ○ Water, carbon dioxide, temperature, humidity
  • It lets more CO2 in than the natural environment
    Lets pests and animals

Question 15

advantages of hydroponics?

Answer 15

• control over conditions like temp, pH balance, light, water and minerals
• also uses less space

Question 16

disadvantages of hydroponics?

Answer 16

uses lots of water

Question 17

disadvantage of glasshouse farming?

Answer 17

expensive, pollutes air, vulnerable to hail and rain fall

Question 18

advantages of battery farming?

Answer 18

higher yield

less expensive

Question 19

disadvantages of battery farming?

Answer 19

cruel
