Intro To Ecosystems
The study of the relationship between an organism and it's envireonment
Ecology
The exchange or conversion of nutrients from one form to another through biological and chemical processes.
Nutrient Cycling
The linear representation which shows the flow of energy from one organism to another
Food Chain
Ecological Succession
The process by which ecosystems advance toward a climax community through development of stages over time
The 3 of the 6 areas that are managed
Air, Water , Soil, Wildlife, Fisheries, Timber
The 4 examples of biomes
Aquatic, Forest, Grasslands, Wetlands
3 of the 5 cycles we studied
Water, Oxygen, Carbon, Nitrogen, Phosphorus
All energy comes from this
The Sun
The 2 types of succession
Primary and Succession
Monitors air quality
Environmental Protection Agency (EPA)
The 2 types of aquatic biomes
Freshwater and Marine
When plants release water vapor during photosynthesis and respiration
Transpiration
The last step of the food chain
Detrivores or Decomposers
Lichens, such as fungi, algae and cyanobacteria
Pioneer Species
Includes plants, animals and other living organisms living in the wild (not domesticated)
Wildlife
Non-living Factors
Abiotic
The process of converting CO2 and H2O into glucose and O2
Photosynthesis
Many food chains interacting with one another in a community
Food Web
Occurs on fertile, open soil where other communities once thrived
Secondary Succession
The act of responsibly using and conserving resources in a way which supports long-term ecological balance
Sustainability
The 5 ecological levels from largest to smallest
biosphere>ecosytems>communities>populations>organisms
The process that makes the Nitrogen cycle possible
Nitrogen Fixation
Apex Predator
Physical change through time
Temporal Change
Manages migratory birds, marine fish and endangered species
