living world Flashcards
what are abobic
are non living such as air water heat
botic
are living things in a ecosystem plants and animals
what are producers
these converse energy from the environment milky sunlight into sugar
consumers
there get energy from sugary produced by produces
decompose
these break down plants and animal materials and return the nutrient to the soil
food chains
all, the connections between produces and consumers
food web
all the connections between produces and consumers in a complex way
nutrient cycling
when plants or animals do the decompose help the recycle
describe the pattern of global ecosystem around the world
rainforest are located near the equator cancer and capiacorn the hottest desert African South America
tundra are fround in the high lattiduces
characteristics of global ecosystem
amazon rainforest
closer to the equator
high temp and heavy rainfall associated with the equator low pressure creates ideal conditions for plants to grow rainforest covers 6 per cent of the earths land and surface
the desert have a low level of precipitation
low levels due to air is so dry leads to do condensation
tropical rainforest is vary hot and wet
its hot due to the low laterite s solar radiation is high and its wet due t the moist air
tundra is cold and dry
igher latitudes receive less solar radiation
what is the soil like in tropical rain forests
Most of the soil is not very fertile
layers of the rainforest
emergents
canopy
under canopy
shrub layer
emergents
highest layer with tress reaching 50 metres
canopy
most life is found here as it reaches 70% of the sunlight and 80% of the life
under canopy
canoeist of tree that reach 20 meters high
shrub layer
lowest layer with small tress that have adapted to living in the shade
name all the plants adaptations
drip tips leaves
butteress roots
spicy leafs
drip tip leaves
so its pointing down so it doesn’t snap the water runs off
buttress roots
they grow from the surface before they get washed away leaching large tress stop them
spicy leafs
stop the animals from eating the plants
learn to grow up trying to reach the sun light
are all the animal adaptations animals
sloth
rhinoceros beatal
frog
spider monkey
sloth adoptions
sloth slow metabolism canl came down to forest flow once per week because the areas is two risk of predators sharp claws to gip branches in the canopy
rhinoceros beetles
claw on head for define abasing predators hard shell to prevent being eaten
frog
suction pads on feet to be able to move around the wet flors poison under skin to prevent begin eaten be=rightly coloured they can attack mates
spider monkeys
tall arms so they can hang from tree to tree
what caused deforestation
commercial reaching rearing cattle for the production of meat
small scale subsistence farming
small scale farming with the purpose of growing enough food to feed the family
commercial farming
large scale farming with the purpose of selling what is grown
logging
cutting down and removing trees for the purpose of making something our of wood
impact of deforestation enviromental negative
the Amazon stores 100 billion tonnes of carbon deforestation will release back into the environment
comic of impact deforestation positive
building the trans Amazonian highway 4000 in 1972 has facilitated the movement trade goods
postivate economic impact deforestation 2
logging contributes a huge amount the Brazil economy
the values of a tropical rain forest
tress oxygen
medicine come from the trees in the rainforest
huge biodiversity live in the rainforest
huge water
indigenous tribes native to the area
how can we manage the rainforest
selective logging
ecotourism
education
ewducing debt
conservation
selective logging
is selecting were you want to cut down a tree in the rain forest rather than clear felling
ecoturism
aims to introduced people to the natural words to benefits local communication and protects the environment for the future
what is the climate like in the tundra
Tundra regions are always colder than 10oC and in the winter average about -35oC.
what is the climate like in the polar
few scientist live there long cold winters, with annual temperatures mostly below freezing
what is the soil like in the polar
covered in ice throughout the year.
what is the soil like in the tundra
permanently frozen for much of the year and is known as permafrost close
what are plants like in the tundra
Plants are usually very small in the tundra This is expected because there are not many nutrients in the soil,
what are plants like in the polar
mosses, lichens, sedges, grasses, and dwarf woody shrubs
what is the tundra like
coldest
short growing seasons
extremely low temp
little amount of perciperation
3-12 in summer
which one is colder polar or tundra
Polar regions are always colder than 10oC
developing opportunities in Alaska
fishing
energy development
minerals extraction
tourism
fishing in Alaska opportunity
tit has employed about 10% of alaskan people 78500 job created
this is good because Alaska is know for there rich marine life with abundance of species like salmon habitats and crabs this means that there plenty of jobs available which can provide a good income
what are the problems of fishing in Alaska
cumerstion farming causes leads to over is hing which coat affect the tourism food fishing serval for a year
mineral extraction opportunity facts for alaska
1.5 Alaska mining wealth comes from gold gold mining contributes 2.2 billion to Alaska GDP in 2013
mineral extension Alaska opportunities Alaska
this abundance creates numerous jobs in mining extraction industries proving employment opportunities for local residents and attracting workers from other areas
why is mineral extension a problem
mining loes lost of chemical in the atompher this can lead on to pollution water which will affect huge amount of there biodiversity
development challenges in Alaska
extraction temp
accessibility
building infrastructure
extreme temp challenge in Alaska
ground permanently frozen permafrost
in the winter theses mouths without sunlight
why is extreme temp a challenge
lack of ability to produce crops
health living conditions difficulty to live there
difficult to build permatly frozen
accessibility a challenge in Alaska
so few people live there that most of Alaska dose not have proper roads
accesablity in Alaska what is that a challenge
the low population density of loss than one person per square kilometre means and explore must make there own access the tundra
threats to cold environments
oil spills
tourism
mining
economic
how is tourist a threat to the environment
off roads vehicle can damage land this will take years to repair can bring lots of noise to the environment to the animals
oil spills a threat to the environment
people for drinking water is contaminated
cost of money for oil spills
lots of biodiversity rented by this
why dose cold eveiroments need protection
social
home to induces rises
provide food homes and energy resources for humans
economic these country’s make money government through truism by fishing mining extraction
envirmomental
loss of biodiversity from loss of animal change
