lesson 7 - biomes produce foods

Question 1

agriculture yield

Answer 1

the agriculture output per hectare of land
eg. crop yields, milk yields

Question 2

how big is a hectare?

Answer 2

10 000m²
its about the size of 2 small soccer fields or one maximum sized soccer field

Question 3

what affects the yields?

Answer 3

different types of production have different yields
if you increase the yield, you don’t have to use as much land to produce the same amount of food/fibres

Question 4

the green revolution

Answer 4

• from the 60s to 70s
• 77% of increase in food production has been because we are producing more per hectare of the land we already use
• encouraged the use of technology like tractors and genetically modified crops

Question 5

where is rice mostly produced?

Answer 5

• produced in every continent except Antartica
• mostly in Asia
• rainforest biomes are best

Question 6

where is wheat mostly produced?

Answer 6

• produced in every continent except Antartica
• mostly Europe and America
• grassland biomes are best

Question 7

what is the best daily temperature for growing wheat?

Answer 7

20 - 25

Question 8

what is the best daily temperature for growing corn?

Answer 8

22 - 25

Question 9

what is the best daily temperature for growing rice

Answer 9

Question 10

what is the best daily temperature for growing potatoes?

Answer 10

15 - 20

Question 11

what is the best daily temperature for growing soybean?

Answer 11

25 - 28

Question 12

what nutrients do plants need?

Answer 12

• nitrogen
• phosphorous
• potassium

Question 13

how does topography affect agricultural yields?

Answer 13

• when the rain falls, it falls evenly on all areas of the farm
• the rain doesn’t wash the nutrients of the soil away
• it’s easier to plant seeds and then collect/harvest the crops
