A biome is composed of different ecosystems. An ecosystem is composed of various communities.
What is the difference between biome and an ecosystem?
100
Is the process of change over time in an ecosystem involving pioneer, intermediate and climax communities
What is succession?
100
Changes in a community in an environment due to altitude, latitude, tidal levels.
What is zonation?
100
The rate per unit area or per unit volume at which biomass consumable as food by other organisms
Productivity
100
soil, fossil, fuels, water bodies.
What organisms include (organic)?
200
Desert
Name the biome with the lowest productivity
200
Lichen and moss
During successions, name 2 types of pioneer organsims
200
Human activities such as: intensive agriculture use, use of fire and resource use.
Describe one factor that can interfere with the process of zonation
200
Gross Primary Productivity minus respiratory losses.
How is Net Primary Productivity calculated?
200
Involves transformation and transfers.
What involves when the ecosystem link together?
300
Insolation, precipitation and temperature
Which are the main factors governing the distribution of biomes?
300
Patterns of energy flow, gross and net productivity and mineral cycling
What changes over time in the process of succession?
300
Local and global scales
In which two scales can zonation occur?
300
GSP= Food eaten-faecal loss
Formula for GSP
300
Human activities; fossil fuels, deforestation, urbanisation and agricultural impact.
What impacts energy flows?
400
Aquatic biomes: Fresh water, wetlands, marine, coral reef, estuaries Terrestrial biomes: Tundra, rainforest, sabana, temperate forest, temperate grassland, desert
Name 3 biomes of each category
400
"R" strategy
What reproductive strategy do pioneer organisms use?
400
NSP=GSP-R
Calculation of the net secondary productivity
400
Consumption, death, decomposition, photosynthesis, respiration, dissolving and fossilization
What make up the carbon cycle?
500
Individual, species, population, community, ecosystem, biome
Name the different classification of individuals until you get to biomes
500
Due to the low amount of producers in the area.
Explain why during the early stages of succession gross productivity is low
500
Sublitoral, Litoral and Supralitoral are examples of
What are examples of zonation?
500
to Net Primary or net secondary productivity of a system
Maximum sustainable yields are equivalent to?
500
Deforestation, urbanization and agriculture are the carbon and nitrogen cycles
Ecosystems that impacts the most?
