Q

How is carbon dioxide removed from the air?

A

Trees and plants carrying out photosynthesis

18
Q

What do plants store carbon as?

A

Glucose (or cellulose/starch)

19
Q

When plants and animals decomposed, their remains can be transformed by heat and pressure over millions of years. What is this resource?

A

Fossil fuels (coal, oil, gas)

20
Q

Process by which fossil fuels are burned in factories/vehicles

A

Combustion (burning in oxygen)

21
Q

The number of one species in an ecosystem

22
Q

All the living species in the ecosystem

23
Q

All the living and non-living factors of a habitat

24
Q

The variety of species in an ecosystem

25
Consequence of adding too much fertiliser to fields (effect on water)
Eutrophication
26
Formed when fertilisers enter water - this blocks out light
algal bloom
27
This resource is used up in the water when bacteria feed off dead plants and animals
Oxygen
28
A human impact caused by poaching
Species extinction / vulnerable species
29
What is a INNS?
Invasive Non-Native Species (e.g. grey squirrel)
30
Name another invasive species in the UK
Japanese knotweed Rhododendron American mink
31
What is the effect of invasive species?
Outcompetes native species (sometimes to extinction)
32
Name an abiotic factor
``` Light intensity pH Temperature Moisture Wind velocity ```
33
How would you measure light intensity
Hold light meter away from body - sensor directed to the sun
34
How would you measure wind speed?
Anemometer
35
How would you measure soil or air temperature?
Thermometer
36
How would you measure soil moisture?
A moisture meter/probe
37
What is an indicator species?
A species whose presence or absence can show the quality of the ecosystem
38
What is an SSSI
Site of Special Scientific Interest (for rare plants, animals or geological features)
39
What can SEPA (Scottish Environmental Protection Agency) do?
- Protect against flooding - Monitor river/sea water quality - Help enforce environmental law
40
What does the SNH (Scottish Natural Heritage) do?
- Educate people on environmental issues | - Conserve natural heritage
