Ecosystems: slapton ree beds,global ecosystems, tropical rainforests, amazon rainforest

organisms in an ecosystem

producer, consumer, decomposer

Ecosystem

all the living and non living parts in an area

organisms in an ecosystem

Ecosystem

all the living and non living parts in an area

abiotic

non living

biotic

living

producer

uses sunlight energy to produce food

consumer

gets energy by eating other organisms

consumer example

rabbits eat grass, foxes eat rabbits

decomposer

gets energy by breaking down dead material

decomposer example

bacteria and fungi

food chain

what eats what

food web

lots of food chians and how they overlap

what does each part of an ecosystem depend on

eachother, consumers depend on producers as a habitat and as food

what are the slapton reed beds

small scale ecosystem in devon

slapton ree beds

fresh ater lagoon separated from the sea by a shingle barrier, contains one of the largest fresh water reed beds in devon

consumers in slapton reed beds

moth larve and water voles, feed on the reeds

producer in the slaption reed beds

common reed

slaption reed beds food chain

common reed, moth larva, eel, bittern

food chain order

producer, primary, secondary, tertiary consumer

food web in slapton reed beds

common reed, moth lava and water beetle, dragonfly and dragonfly larva, eel and frog, bittern

what eats moth larva

dragon fly, dragonfly larva, frog, eel

what eats a water beetle

dragonfly, frog

what type of ecosystem is slapton reed beds

interdependant, all components depend on eachother

the knock off effect if drought dries up pools

insect larvae die, fish and frog population decrease, bittern numbers decline

knock off effect if the nutrient runoff from farm land enters lagoon

increased surface algae growth limits light entering lagoon, winterweed in lagoon die, waterbeetles have less food, fish an eel population decline

Types of global ecosystems

tundra, grasslands, temperate deciduous forest, boreal forest, polar, hot desert, tropical rainforest

types of global ecosystems- tundra

found at high latitudes, northern europe canada and alaska, winters are very cold, brief summers, little rainfall, hardly any trees

types of global ecosystems- 2 types of grasslands

savannah and temperate

2 types of grasslands- savannah

found between tropics, distinct dry and wet seasons, low rainfall, most vegetation is grass with a few trees

2 types of grasslands- temperate

found at higher latitudes, more variation in temperature and less rainfall, no trees just grass

types of global ecosystems- temperate deciduous forest

found in mid latitudes, 4 distinct seasons, warm summers, mild winters, rainfall all year round, deciduous tress lose leaves in winter

types of global ecosystems- boreal forest

other name is taiga, found 50 to 60 degrees north, cold and dry winters, mild and moist summers, confinerous trees

types of confinerous trees

evergreen and needles

types of global ecosystems- polar

found around the north and south poles, very cold, icy, and dry, remain dark for serveral months each year

types of global ecosystems- hot deserts

found 15 and 35 degrees north and south of equator, little rainfall, hot during day, cold and night, shrubs and cacti grow there

types of global ecosystems- tropical rainforest

found around the equator, between tropics, hot and wet year round, dense canopies of vegetation form destinct layers

tropical rainforest- climate

same all year round, temp is between 20 to 28, rainfall is high around 2000 mm per year

tropical rainforest- plants

evergreen trees, tall trees and vegetation cover is dense, not much light reaches forest floor, lots of epiphytes

epiphytes

plants that grow on other plants, orchids and ferns

tropical rainforests- soil

isn't very fertile, heavy rain washes nutrients away, nutrients at the surface due to decayed leaf fall, layer is very thin

troipical rainforests- animals

contain more animal species than any other ecosystem

animals in the rainforest

gorillas, jaguars, anacondas, tree frog, sloth, howler monkeys

tropical rainforest- people

inhabitants adapted to the forest environment over generations

Why do tropical rainforests have high biodiversity

high temperatures, high rainfall means plants grow rapidly, wet and warm climate means there is growth year round, wide variety of plants provides a lot of habitats and food,
lack of human activity means plants and animals are undisturbed

why rainforests good ecosystems

warm and wet climate helps fungi and bacteria on forest floor decompose dead plnat material quickly

what type of ecosystem is the rainforest

interdependent

how are humans interfering with rainforest ecosytems

deforestation
