Ecosystems
Food chains
Producers
Plants make their own food via photosynthesis
Primary consumers
Herbivores = eat plants = cows / rabbits
Secondary consumers
Carnivores = eat herbivores = cat / fox
Top carnivore
Carnivore = eats other carnivores (mainly on a lower tropic level) = lions / wolves
Decomposers

There are interrelationships
Physical
animals eating plants
Chemical
acid rain speeds up decomosition
Physical + human forces
extreme weather
Droughts can kill many trees
storms can cause trees to fall
storm in 1987 caused 15 million trees to fall
Human forces
DEFORESTATION
can lead to leeching
climate changed caused by humans
Changes to population
If a certain animal in a food web dies the whole web is affected
If tropic level one increases
more trophic level 2 and 3
more competition between species on trophic level 2 for natural resources due to increased population
Ecosystem distribution and characteristics
Tropical rainforests
along equator. high concentration of suns rays allows for moist air and heavy rainfall perfect for immense amount of flora
Deserts
close to tropic of cancer and Capricorn. very little moist air with lots of sun creating arid and dry conditions. limited flora and fauna
