9 of 45
Deserts

12 of 45

Less than 500mm rain, warm summers, very cold winters, coniferous trees
13 of 45

14 of 45
Biosphere
The layer of the earth where life exists, it is made of living organisms
15 of 45
Exploitation
The way in which we make use of the Earth’s resources
16 of 45
Resource
A stock or supply of something that is useful to people
17 of 45
Abiotic
Non living parts of an ecosystem
18 of 45
Biotic
Living parts of an ecosystem
19 of 45
Terrestrial
A terrestrial ecosystem is an ecosystem found only on landforms
20 of 45
Woodland
Broad leaved trees, leaves lost in autumn and regrown in spring.
21 of 45
Moorland
Land which is not intensively farmed. Thin, acidic, peaty soils. Upland areas that are too high to be used for crops
22 of 45
Wetlands
Low lying, wet and boggy
23 of 45
Heathland
Open countryside in lowland areas
24 of 45
Inshore habitats
Close to the shore and important for recreation and tourism
25 of 45
Offshore ecosystems
Found away from the shore and are important for commercial fishing and energy production
26 of 45
Eutrophication
When fertilisers from farmlands are washed into the sea
27 of 45
Sustainable
Improving things now but keeping them for the future
28 of 45
Biodiversity
Having a range of plants and animals
29 of 45
Herbivores
Eat plant matter
30 of 45
Detritivores
Eat dead matter
31 of 45
Carnivores
Eat meat
32 of 45
Drip tip leaves
Leaves have waxy surfaces and pointy ends enabling excess rainfall to run off easily. This prevents the build up of algae, which could block sunlight and prevent photosynthesis
33 of 45
Leaf angles
Leaves are arranged at different angles so they don’t block sunlight from each other
34 of 45
Buttress Roots
Because nutrients are concentrated in the top layer of soil, TRF trees only need shallow roots but they also keep the tall trees anchored upright
35 of 45
Deforestation
Permanently removing forest so it can be used for something else
36 of 45
Sustainable management
Meets the needs of the current population without compromising the needs of future generations
37 of 45
Ranching
Clearing forest for grazing
38 of 45
Felling
To cut down a tree
39 of 45
Logging
the activity or business of felling trees and cutting and preparing the timber
40 of 45
Ecotourism
Tourism which allows people to enjoy themselves without causing harm to the environment
41 of 45
Large leaves (DW)
Increases photosynthesis. Leaves can lose a lot of water through stomata in summer
42 of 45
Leaves are shed in the autumn
Due to reduction in heat and light
43 of 45
Thick bark
Protects the tree against frost
44 of 45
Hibernation
Animals hibernate in the winter
