A flock of geese are traveling together when a large storm hits, killing off 3 of the geese. Is weather a density-dependent or density-independent factor?
Density-independent (doesn't matter how dense the population is)
400
What is a pioneer species? Give one example.
A pioneer species is the first species to colonize an ecosystem after a disruptive event. An example would be grasses

Evaluate the type 3 line on this graph. How many offspring would you expect an individual of this species to produce? What happens to their chance of survival as they get older?
In a type 3 curve, a large number of offspring are produced, but only a few make it to adulthood. Most that make it to adulthood will live to an old age.

Using your whiteboards, draw an exponential graph. Then alter your graph to demonstrate the carrying capacity of the species. Make sure your graph is labeled!
500
Why can invasive species populations increase so quickly?
Lack of predators, abundance of food, ideal conditions

Is this a density dependent or density independent factor?
Density-dependent, the factor has an increased effect as the population increases.
