NOTES 3 Flashcards
WHAT ARE THE FUNCTION OF ECOSYSTEM
- Productivity
- Decomposition
- Physical (Energy Flow)
- Biological (food chains, food web, ecological succession)
- Biogeochemical (nutrient cycling) processes
is transmitted to
different trophic levels along the food chain.
Energy from an energy source - Chemical or Solar
is the avoidance of the depletion of natural resources in
order to maintain an ecological balance
SUSTAINABILITY
energy can neither be created nor
destroyed, it can only change from one form to another
First law of thermodynamics
refers to the solar radiation between 400 to 700 nm that
photosynthetic organisms utilize for photosynthesis
- part of electromagnetic radiation that can be used as the source of
energy for photosynthesis by green plants
Photosynthetically Active Radiation (PAR)
as energy is transferred more, more
of it is lost in the process
Second law of thermodynamics
regulation of carbon dioxide and oxygen
atmospheric gas supply
the benefits that organisms receive from the environment and its resources
ECOSYSTEM SERVICES
WHAT ARE THE 4 PILLAR/DISTINCT AREAS OF SUSTAINABILITY
- Human
- Social
- Economic
- Environmental
EXAMPLES OF ECOSYSTEM SERVICES:
1.atmospheric gas supply
2.climate regulation
3.cultural benefits
4.food production
5.habitat
6.water supply
regulation of greenhouse gases
climate regulation
aesthetic, spiritual and educational value
cultural benefits
crops, livestock, fish
food production
storm protection, flood control, drought recovery, and other aspects of environmental response to disturbances
disturbance regulation
habitat for migratory species and for locally harvested species, overwintering grounds, nurseries
habitat
