1

What is an ecosystem

A group of organisms and their environment

2

What three things can an organism be classed as in an ecosystem

Decomposer
Consumer
Producer

3

Describe the nutrient cycle and a way of remembering it

Animals come in, then decompose (along with plants) into the ground. The tree then consumes these nutrients from under the ground and then deposits them through their leaves where the cycle begins again

4

what are the producers and consumers in wayland woods

temperate desciduous trees
birds foxes etc

5

what is the difference between each 3 organism classifications

producers- use energy from the sunlight to do photosynthesis
consumers- eat the producers
decomposers- organisms and microorganisms such as fungi and insects that break down into the ground giving it nutrients

6

list all types of biomes in the world and their characteristics and where they are found

desert- less than 25cm of precipitation per year. found on the tropics
grassland- distinct dry and wet seasons with lots of grass
temperate desciduous forest- four distinct seasons and found on the mid latitudes
rainforest- found on the equator. hot and wet all year round
polar- cold, icy and dark all year round
tundra- found at high latitudes. very cold winters and short summers. found in places like canada

7

what is a biome

A biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents.

8

what is the climate and vegetation of the amazon

9

what are the four layers of a rainforest

shrub, under canopy, main canopy, emergent layer

10

11

animal adaptations to living in the amazon

short wings so they can maneoivre themselves
flying frogs develop flaps to gluide from tree to tree

farming- families are using it for personal profit
cattle- burn trees down
logging- chop down trees for profit
mining- self explanatory

13

local and global impacts of amazon deforestation

global- more co2 in the atmosphere as trees arent absorbing it for phototynthesis
local- loss of tourim but more space for things listed above and also loss oh animals and their habitats (ecosystems)

14

three strands of sustainability

social
enviromental
economic

15

four ways in which the brazilian govt can reduce deforestation

education
reducing debt
international agreements
conservation

16

what is your example of sustainable tourism and how is it sustainable

costa rica
-it educates about the surrounding enviroment
-it provides the local community with jobs
-visiters engage with the local community

17

what two things are special about your uk ecosystem

temperate descidous forest
sss1 sight (protected by local authorities)

18

three ways rainforests can be sustainably managed

selective logging
replantation
ecotourism

19

why are rainforests found near the equator

high temperatures cause fast evaporation of water
