- 1EcosystemAll of the organisms in a given area plus the physical environment in which they interact
- 2Ecosystem ServicesEssential ecological processes that make life on Earth possible.
Benefits: nutrient cycle, air and water purification.
Ecosystem Goods: Food and Fuel - 3Net Primary ProductivityA measure of the amount of energy captured via photosynthesis and actually stored in the photosynthesis organism
- 4Food SecurityHaving physical, social and economic access to sufficient, safe and nutritious food.
Ex: Livestock Rearing - 5Food SovereigntyThe right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems.

- 9AcclimationAdjustments made by a particular individual daily, seasonal: going into hibernation, starting migration, moving from the sun to the shade.
(ADJUSTMENTS TO CONDITIONS)
Ex: birds migrating south for the winter. - 10AdaptationGenetic changes through natural selection that improve and organisms ability to carry out daily/seasonal life-cycle functions for growth, maintenance and reproduction.
Ex: elephants migrating, due to lack of water. - 11Liebig's Law of MinimumThe health and well-being of any individual organism is controlled/determined by the availability of the scarcest resource(limiting factor)
Ex: Caribou migration - 12Ecosystem Services relation to provisioning servicesThey are ecosystem services that describe the material or energy outputs from ecosystems.
Ex: food, water and other resources. - 13Ecosystem services relate to regulating servicesThe services that and ecosystem provides by acting as regulators.
Ex: air regulation, water regulation - 14The F's of NPPFood, Fuel, Fibers, Fabrication
- 15Best waste product?Oxygen.
Plants give it off (waste), yet everyone else absorbs it. - 16The limiting factor of global scale NPP?The carrying capacity of Earth.
- 17Carrying CapacityThe populating size that an area can support dor the long term.
It's possible that an abiotic or biotic threat may coming to decrease the population of the species. - 18HabitatThe physical environment in which individuals of a particular species can be found.
Ex: Prickly pear cactus in desert areas - 19NicheThe role a species plays in its community.
Ex: A fungi plants eating the decaying plants/animals on the ground - 20SlaveryThe loss of one's access to and control over land, labor and food supply
