Sort the following into density dependent and density independent factors:

  • Ex = natural disaster

  • Typically leads to a population reaching a carrying capacity

  • Typically causes a logistic growth pattern

  • Ex = extreme weather events

  • Ex = disease/parasites

  • Effect does not intensify or vary as a population increases in density

  • Regulates population growth through mechanisms like intraspecific competition

  • Ex = intraspecific competition

  • Effect intensifies as a population increases in density

  • Density dependent limiting factors

  • Density independent limiting factors

Sort the following examples into density dependent and density independent factors

  • Parasites are being passed throughout a population due to contaminated water

  • Gazelle's are competing for limited food

  • Penguins are competing for limited space to breed and raise their offspring

  • There is a chemical spill that kills of a large portion of a species of fish

  • There is a drought that affects water availability for African elephants

  • Deforestation is occurring in a rainforest that is affecting access to nesting locations for a species of bird

  • E coli is spreading throughout a population

  • There is a wildfire that destroys the habitat of many tree frogs

  • Density dependent limiting factor

  • Density independent limiting factor

Look at the above graph and explain one full predator prey cycle using specific data. This should be a relatively detailed answer (my answer is about 8 sentences).
