Ecology Flashcards
How much energy is lost during each transaction
10%
What is a producer
The primary source of energy usually plants
What is a consumer
The consumer of producers or other consumers
What is a decomposer
The consumer of dead animals
What is the pyramid structure
The top animals are at the top but little in number and its prey and its preys prey is below each other. The lowest are usually the highest in number due to the 10% rule
Carbon cycle
6Co2+ 6h2o-> c6h12o6+6o2 photosynthesis
c6h12o6+6o2-> 6Co2+ 6h2o cellular respiration
Life-> fossil fuels
Fossil fuels-> 6Co2+ 6h2o
Nitrogen cycle
N2-> nh3,nh4+(ammonia, ammonium) nitrogen fixation
Waste-> nh3,nh4+(ammonia, ammonium) ammonification
Nh3,nh4+-> no2-,no3-(nitrates) nitrification
no2-,no3- -> life(animo/nucleic acids)
no2-,no3- -> n2 denitrification
Watercycle
Liquid -> gas evaporation Plant liquid -> gas transpiration Gas -> liquid precipitation Liquid from body of water flowing off. run off Liquid-> ground percolation
How does the prey chain work
Producer(grass) ->primary consumer(cricket)-> secondary consumer(mouse)-> tertiary consumer(fox)-> quinary consumer(wolf)
Intra vs inter
Intraspecific: competition within a species
Interspecific: competion between 2 species
Symbiotic relationships
Mutualism
Commensalism
Parisitism
What is a niche
The specific duty of a species in a ecosystem
Exponential growth vs logistic growth
Exponential is currently continuing
Logistic has capped off and hit the carrying capacity
Population growth curves
The species that preys on an extremely high level of prey will lag behind so it will grow the most a season or 2 behind the fall of the prey
Carrying capacity
The most of a population an ecosystem can hold
