Recap: Yesterday's Activity
Yesterday we engaged in an activity where we saw how different environmental factors or resources (food, water, shelter) could influence the size of a wolf population.
Which best describes what happened to the wolf population when wolves could not find what they needed to survive?
Their population size stayed the same
Their population increased in size
Their population decreased in size
Which best describes what happened to the wolf population when wolves had plenty of access to the resources they needed?
In ecology, resources that organisms need can also be called Limiting Factors. Which of the following is the best definition for this key term?
Environmental factors that are all abiotic
Resources that are all biotic
Resources that may cause a species' population size to change
Environmental factors that affect predators but not prey
The graph shows the growth of a population of coyotes in a wilderness area. State one possible cause for the population decrease at X.
