2.

Individuals of different species in the same area are known as a ....

Question 3
3.

Sort the following into density dependent and density independent factors:

  • Typically causes a logistic growth pattern
  • Ex = intraspecific competition
  • Ex = disease/parasites
  • Ex = natural disaster
  • Ex = extreme weather events
  • Effect does not intensify or vary as a population increases in density
  • Effect intensifies as a population increases in density
  • Typically leads to a population reaching a carrying capacity
  • Regulates population growth through mechanisms like intraspecific competition
  • Density dependent limiting factors
  • Density independent limiting factors
Question 4
4.

Sort the following examples into density dependent and density independent factors

  • Parasites are being passed throughout a population due to contaminated water
  • Penguins are competing for limited space to breed and raise their offspring
  • E coli is spreading throughout a population
  • There is a drought that affects water availability for African elephants
  • There is a wildfire that destroys the habitat of many tree frogs
  • Gazelle's are competing for limited food
  • Deforestation is occurring in a rainforest that is affecting access to nesting locations for a species of bird
  • There is a chemical spill that kills of a large portion of a species of fish
  • Density dependent limiting factor
  • Density independent limiting factor
Question 5

In a predator prey cycle what generally happens when the prey population size increases?

Question 6
6.

Explain why in 1 sentence. This will be marked wrong but once you submit you can compare your answer to mine.

In a predator prey cycle what generally happens when the prey population size starts to decrease?

Question 10

Explain why in 1 sentence. This will be marked wrong but once you submit you can compare your answer to mine.

Question 13
13.

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).
