Chapter XX- Ecology Flashcards
Ecology
-study of interactions among organisms and their environment
Population
- interbreed
- same place at same time
- ONE SPECIES
Community
-inreracting populations
Biome
-large group of ecosystems
Biosphere
-supports life
Tolerance Curves
- performance graph
- cant survive out of this
Acclimation
- adjusts tolerance levels
- slowly adapts
Transpiration
Water evaporating from plants
Percolation
Collection of warer underground
Habitat
-organism lives
Niche
-role of a species in an environment
Generalist
-eats many different things in many ways
Specialist
- eats 1 thing in kne way
- adapted towards 1 resource
Fundamental
- potential organisms can get to
Realized
- range it actually uses
Scavengers
Feed on dead animals
Decomposer
Break down and aborb nutrients from dead organisms
About ____% is transferred at each level of a food pyramid
10%
Trophic levels
Feeding steps
Limiting factors
- food
- predators
- temp
- light
Symbiosis
Interactions among species
Parasitism
Parasite feeds off host
Mutualism
++
Commensalism
+\0
Succession
Natural changes in an environment
- fast= decades
Climaz communities
- balanced food web
Exponential Growth
- increases rapidly
Think of a J
Logistic Model
Carrying capacity is reached
Density independent favtors
Natural disasters/ cants control
Density dependent factos
Worse when theres more of it
Biodiversity
Species richness
