farming and food security. Flashcards
what is intensive farming?
farmers try to produce as much food as possible from the land, animals and plants they have.
What is organic farming?
farmers produce smaller amounts of healthier, high-quality food with no artificial chemicals.
what are some examples of intensive farming?
Hydroponics
Battery farm
Inserticides
Fertilisers
Removing hedgerows
Pesticides
Antibiotics
Fish farms
herbicides
what are some examples of organic farming?
Greenhouses
Biological control
Crop rotation
Weeding by hand
manure
what is good about intensive farming?
Very efficient
High crop yield
energy losses in the chain are reduced?
Explain why herbicides decrease energy loss in the food chain?
less competition from weeds for light energy.
More of the Sun energy is entering, desired food chain.
explain why pesticides decrease the energy loss in the food chain.
No energy is transferred into different food chains via the pest.
More energy is used for growth of crop.
explain why battery farming decreases energy loss in the food chain.
Animal kept close.
They are warm and move less.
Don’t waste energy, moving or trying to keep warm.
More energy is used for growth of crops.
what is food security?
Having enough food to feed the population.
How can you improve food security?
improving crop yields
Intensive farming techniques
Sustainable fisheries
Biotechnology
