Population Ecology
They are non-living aspects of an ecosystem (pH, water, sunlight)
What are abiotic factors?
They are reservoirs that take in more carbon than they release
What are carbon sinks?
They have very restricted tolerance ranges and can only occupy very particular niche spaces
What are specialists?
They consume both primary producers and other consumers
What are omnivores?
It refers to the amount of energy reflected, determined by the surface material
What is albedo?
It's when organisms exit a population.
What is emigration?
It's the process that removes CO2 from the atmosphere
What is photosynthesis?
It occurs if there is a "winner" that completely prevents another species from using the resource
What is competitive exclusion?
They consume/break down nonliving organic matter like leaf litter, waste products, carcasses of animals
What are decomposers/detritivores?
It is a limiting factor where availability changes with population size
What is a density-dependent factor?
It's when population grows by a fixed percentage each year
What is exponential growth?
It adds CO2 to the atmosphere from the biosphere.
What is respiration by animals?
What is mutualism?
They use cellular respiration to make use of chemical energy from primary producers
What are consumers or heterotrophs?
It's when occurs when a disturbance completely removes all vegetation and life
What is primary succession?
It's when life expectancy is low, so parents invest into having many offspring to improve the odds of some of them surviving long enough to reproduce
They are reservoirs that release more carbon than they take in
What are carbon sinks?
It's the ability to survive and reproduce under changing environmental conditions
What is tolerance?
They have a disproportionately large impact on a community relative to their abundance
What is a keystone species?
It's when organisms live in groups or cluster around limited resources
What is clumped distribution?
Its the total # of individuals/area
What is population density?
This human activity increases CO2 in the atmosphere.
What is burning fossil fuels?
It's when one species benefits and another is unaffected.
What is commensalism?
It's an organism’s rank within its community’s feeding hierarchy
What is a trophic level?
What are Dr. Willett's cat's names?
