Q

Steps of quadrant

A

1- take quadrat to flowery field
2- place the tape measure in a section of the field
3- randomly collect numbers to use for co-ordinates (10 pairs
4- place the quadrat on your first set of co-ordinates
5- count the species inside the quadrat
6- repeat with all other co ordinated
7- add all of the flower numbers up
8- multiply by size of field
9- repeat

Q

What is the source of all energy in a food chain

A

The sun because it produces plants through photosynthesis

15
Q

Why is all energy not passed on to the next trophic level

A

Because we only take in 10% of energy since we lose most of it because it is inedible or not digestible, we also lose the energy in respiration, movement, and feces/urine (waste)

Q

Pyramid of numbers

A

Always keep height the same
Make up the scale factor
If it’s not a pyramid shape then use a pyramid of biomas

Q

Pyramid of biomas

A

Times amount of leaves by mass
Do the same for all
Think of a scale factor
And make magic

Q

Plants need water for

A

Photosynthesis

20
Q

Plants need sun for

A

Photosynthesis and transportation.

21
Q

Plants need co2 for

A

Photosynthesis

22
Q

Plants neee soil for

A

Nutrients- minerals, chlorophyll production.

23
Q

Plants need oxygen for

A

Respiration (aerobic)

24
Q

Plants need nitrates for

A

Protein production

25
Why do we need to farm fish
High protein for growth and repair of tissues
26
Pests
Eat crops Reduce yield Less profit
27
Spray with pesticide pros
Kill insects so that they don't eat or destroy crops Effective and quick New ones aren't persistnat
28
Spray with pesticides cons
They are toxic to humans and the environment They can effect food chains massively by killing lots of primary consume RS and damaging producers
29
Biological control
When people use a predator to kill a group of organisms
30
Biological control pros
It can get rid of organisms Chemical free
31
Biological control cons
No control over t and predators can end up killing things u wanna keep E.g cane toad The predator needs food
32
Higher temp
Increases chemical reactions in photosynthesis Speeds up growth Increases yield More profit
33
Co2 raw material of photosynthesis higher co2 concentrations
Increases photosynthesis rate Speeds up growth Increases yield More profit
34
Glasshouse advantages
Photosynthesis speeded up, more yield Warmer (greenhouse effecting wave radiation trapped by glass) Can increase co2 levels Artificial light
35
Fertilisers
Farmers use them to make plants grow at a faster rate They can be chemical or manure Can kill/ destroy everything in eutrophicarion
36
Fertilisers containing nitrates added
Increase while Increase growth- improve Gain more profit
37
fish farming perfect tank - Clean water
anti-biotics put in water in control disease water filter so that the fish are constantly provided with clean water and there is no risk of disease/ bacteria developing
38
fish farming perfect tank- the predator prob
farm is seperatd by glass so that big fish of the same species can not eat small fish
39
fish farming- stuff about the tank
made from plastic and re-enforced fibre glass, tank with lowest possible surface area
40
location of fish tank
off shore in deepwater so that it is not in an area crammed with fish farms and there is less bacteria in the water
41
feeding of the fish
fed a controlled diet of pellets with maximises energy transfer. A timer controls how often food is released into the farm
42
why will the fish be great quality
bevcause they are not at risk of disease and are in clean water and they are fed well with the right nutrient
43
greenhouse lighting
evenly spread artificial lights which increase light intensity and help plants photosynthesise and grow at a faster rate especially in winter. They also help in transpiration.
44
greenhouse temp
is built with glass to trap heat | thermistor to control the temp and make sure it is appropriate for growth
45
watering in the greenhouse
sprinklers under the ground which provides plants with necessary water concentration to grow and to use in photosynthesis. Also adds moisture to the soil is controlled by a timer to prevent flooding
46
additives to the soil in a greenhouse
spray fertiliser because they contain useful nitrates spray pestisides to kill weeds and insects manure added to help bring nutrient for minerals and chlorophyll production
47
greenhouse gases
a fan which circulates the gases within the greenhouse. removes oxygen and provides ventilation also a pump which provides c02 from a nearby factory to help plants photosyntheise
