Natural capital
goods or services that aren't manufactured (soil, trees, living organisms)
1 of 31
Natural income
The amount of resources we take from nature a year
2 of 31
Biomass
the quantity of dry organic material in an organism, population, trophic level or ecosystem
3 of 31
Pyramids
models of the quantative differences between the amounts of living material stored at each trophic level of a food chain. Allows us to examine energy transfers & losses
4 of 31
Carrying capacity
maximum no. of organisms that an area can sustainably support over a long period of time
5 of 31
Ecological footprint
The area required to sustainably support a given population
6 of 31
Zonation
Arrangement of plant communities into bands in response to change
7 of 31
Succession
change in community structure of an area over time
8 of 31
Eutrophication
the addition of excess nutrients to freshwater ecosystems
9 of 31
Primary productivity
the gain by producers in energy/biomass per unit area per unit time
10 of 31
Secondary productivity
biomass gained by consumers through feeding & absorption of energy per area & time. Depends on food present & efficiency of consumers making biomass
11 of 31
Gross Productivity
total gain in energy per unit area and time
12 of 31
NP
gain of energy per unit area & time AFTER RESPIRATION losses (energy left for the next trophic level)
13 of 31
GPP
gained through photosynthesis of primary producers
14 of 31
GSP
gain through absorption in consumers
15 of 31
NPP=GPP-R
NSP=GSP (food eaten)-R
16 of 31
Sustainability
Living within the means of nature, on the interest or sustainable income generated by natural income
17 of 31
Sustainable development
meeting current needs without compromising ability of future generations to meet their own needs
18 of 31
Trophic level
is the position that an organism occupies in a food chain
19 of 31
Ecosystem
a community of the living & non-living organisms in their environment
20 of 31
Species
organisms that interbreed and produce fertile offspring
21 of 31
Hybrid
two species that breed together
22 of 31
Population
same species living in the same area and interbreed
23 of 31
Habitat
an environment a species lives in
24 of 31
Niche
where and how a species lives
25 of 31
Community
population living and interacting with each other in a habitat
26 of 31
Diversity
the variation of living life form in a given ecosystem, biome or entire Earth.
27 of 31
Biome
collection of ecosystems sharing similar climatic conditions
28 of 31
Producer
make their own food and help the consumers & decomposers through the input of energy & biomass
29 of 31
Consumers
get energy and nutrients from others
30 of 31
Decomposers
obtain food and nutrients from break down of dead organic matter
