ecology - Coggle Diagram

- - - - natiev species that are found only in that region e.g many of island species such as dodo's
    - - species that have been indroduced by humans accidentally or intentionally
- - - - members of different species cannot reproduce with each other unless exepctions but hybrids are usually sterile
  - - - estimated population and is chosen by using random selected areas
    - - the use of quadrats to sample a area for non motile organisms e.g plants or tunicates
    - - used for highly mobile organisms where capture and marking a organism and later release them. the Lincoln index is used for estimating population size e.g rats or snakes
  - - - negative feedback population control by density dependant factor
        
        the population size can be affected so the density dependent factor will push it back it its carry capacity
- - - - a simplified version of a food web
    - - a simple model of reality specifically about predation
    - - organisms that make thier own scource of energy
    - - organisms that consume for energy
    - - The trophic level of an organism is the position it occupies in a food web.
    - - energy transfer of one trophic level to another
    - - The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth.
- - - - factors that are not caused by living organisms
    - - factors that are caused by living organisms
    - - a variable of a system that causes a noticeable change in output or another measure of a type of system.
    - - deserts
        
        nocturnal behavior
        
        large surface area for heat diffusion
        
        water conserving adaptations such as cactus spikes
      - rainforest
        
        leaves allow water to flow off
        
        mutualism
        
        poison(some times at extreme toxicity)
- - - - keystone species keep a ecosystem functioning
    - - addition of too much nutrients in a body of water
    - - microplastics
