paper 1: 1.3 ecosystems, biodiversity and management Flashcards
name all the large scale biomes
7 of them
- boreal forest
- temperate forest
- tundra
- desert
- tropical rainforest
- temperate grassland
- tropical grassland
what are boreal biomes give an example
mostly pine forests at higher latitudes where the sun’s rays are weaker
canada
what are temperate forests give an example
deciduous forest with seasonal variations, losing their leaves in the winter.
UK
what are tundra biomes give an example
within the artic circle, the sun gives off little energy and there is little percipitation.
northern canada
what are desert biomes give an example
close to the tropics, the suns’s energy is concentrated, making it hot during the day.
sahara desert
what are tropical rainforest give an example
found within the tropics where it is hot and wet
brazilian rainforest
what are temperate grassland give an example
hot in summer and very cold in winter, with rainfall in late spring and summer
mid-USA
what are tropical grasslands give an example
mostly in the tropics, hot all year but always with a dry season
kenya
cliamte
temperature
growing seasons are much longer in warmer locations; the further you move away from the equator the shorter they become.
climate
percipitation
the global circulation system influences percipitation. eg. low pressure found between the hadley cells where warm air rises causing rain.
climate
sunshine hours
lower amount of sunshine towards the poles at certain times of the year means less sunlight for photosynthesis.
local factors
altitude
the higher the altitude, the lower the temperature. this means that differnt plants can grow within the same ecosystem.
local factors
rock and soil type
differnt vegetation can grow in the same ecosystem owing to different types of rocks and soil.
biospheres provide vital resource for people
food from the biosphere include
3 types
- fruits, nuts and berries
- land for growing crops
- fish and meat
biospheres provide vital resource for people
energy from the biosphere include
3 types
- animal dung for burning
- trees (wood)
- fermenting crops (bioethanol)
biospheres provide vital resource for people
medicine from the biosphere include
3 types
- poppies (morphine)
- vitamin C (oranges)
- aloe plant (skin creams)
biospheres provide vital resource for people
building materials from the biosphere include
3 types
- straw for roofing
- timber for construction
- animal dung mixed with clay
biospheres provide vital resource for people
water from the biosphere include
1 point
- water moves through living organisms
biospheres provide vital resource for people
minerals from the biosphere include
3 types
- iron ore
- silver
- copper
what are the UK’s main terrestial ecosystems
4 ecosystems
- moorlands
- heathlands
- woodlands
- wetlands
UK’s main terrestial ecosystems
what are moorlands, where are they found in the UK
are they upland or lowland
heather woodland, peat bogs and rough grasslands
- upland areas
- scotland and northern england
UK’s main terrestial ecosystems
what are heathlands, where are they found in the UK
are they upland or lowland
a mixture of marshes and dry, sandy heathland
- lowland areas
- southern england
UK’s main terrestial ecosystems
what are woodlands, where are they found in the UK
are they upland or lowland
remaining ancient woodlands
(eg. birch and oak)
- lowland areas
- north-east scotland
UK’s main terrestial ecosystems
what are wetlands, where are they found in the UK
are they upland or lowland
waterlogged soils
- lowland areas
- scotland, east anglia
UK marine ecosystem importance
how does tourism help people
provides jobs and an income for the local economy
UK marine ecosystem importance
how does energy help the UK
what type of wind
wind energy is reducing the UK’s reliance on fossil fuels
UK marine ecosystem importance
how does fishing help people
marine ecosystems provide jobs in the fishing industry
UK marine ecosystem degradation
coastal developments
how do they affect habitats
destroy wildlife habitats
eg. salt marsh
UK marine ecosystem degradation
climate change
what does climate change do to the food chain
introduces new specoes which changes the food web
UK marine ecosystem degradation
overfishing
what does overfishing do to the food chain
eg cod
damages the food chain
UK marine ecosystem degradation
fertilisers for farms
what does fertilisers do to the food chains
lead to eutrophication, damaging the food chains.
what are biotic components
name some in a tropical rainforest
5 things
living parts of the ecosystem. eg.plants and animals
- brazil nut tree, parrot, sloth, tree frog etc.
what are abiotic components
name some in a tropical rainforest
5 things
non-living parts of the ecosystem
eg. soil, water, light, temperature, rainfall etc
