sustainability

meeting present needs without compromising future generations’ ability to meet theirs

sustainable management need

vital to keep humanity from running out of resources

water cylce

the continuous movement of water between the Earth and the atmosphere.

label

surface run-off

water flows over teh surface when soil is saturated

inflitration

water moves vertically into the surface

through-flow

water moves laterally thorough the surface

ground water flow

water moving slowly, aquifers,deep underground

thermosphere

mesosphere

stratosphere (ozone)

troposphere

layers of atmosphere

ozone layer

stratosphere, prevents uv radiation from reaching earth’s surface, UV problem not heat,

nitrogen, oxygen, carbon dioxide, methane

major components of atmsphere

greenhouse effect

troposphere , UV in, abosrbed, re-emitted, trapped, inrared heating problem , carbon dioxide, methane, water vapour

biome

A large-scale ecological zone with characteristic

climate & vegetation

Ecosystem

A community interacting with each other AND their

physical environment – all biotic and abiotic

community

All populations of DIFFERENT species in one area at

one time

population

All individuals of the SAME species in one area at

one time

abiotic

non-living

biotic

living

habitat

where an organismo lives

niche

what an organism does -role in ecosystem

predation, competition, grazing

biotic interaction

trophic levels

TL1- producer

TL2- primary consumer

TL3- secondary consumer

TL4- terciary consumer

TL5-Quaternary consumer

trphic levels rule

90% of the energy is lost as heat, movement; only 10% passes to the next level. It is why a pyramid of energy is always widest at the base.

photosynthesis

6H₂O+6CO₂ = C₆H₁₂O₆+6O₂

Aerobic respiration

C₆H₁₂O₆+6O₂ = 6H₂O+6CO₂+ATP

Carbon Cycle

Photosynthesis

Feeding

Respiration

Decomposition

Fossilisation

Combustion

Photosynthesis and Respiration

Phosynthesis absorbs the carbon taking it in

Respiration releases it , putting it back

carbon store

natural or artificial place that accumulates carbon for a periodistas of time , lytoshpere, hydrosphere, biosphere

carbon sink

mechanism or process that absorbs more carbon from the atmosphere than it releases, forests and oceans
