Define ecosystem. What is the difference between them. 4.1 Define what a resource is. How do resources affect population growth? 4.2 What are the three main terms scientists use to describe populations? 4.2 What increase a population’s size? 4.2 What decreases a population’s size? 4.2 Why do scientists use sampling to estimate the size of a population? 4.2 Describe how to perform random sampling. 4.2 Describe the mark and recapture method of population sampling. 4.2 Define population density. 4.2 What are the three types of population distributions? 4.2 How are population distributions in nature typically arranged? 4.2 Describe clumped distribution. 4.2 Describe Random distribution. 4.2 Describe uniform distribution. 4.2 What is the difference between density and distribution? 4.2 What are age structure diagrams? 4.2 What are age structure diagrams used to predict? 4.2 How can high population density be helpful to a population? 4.2 How can high population density be harmful to a population? 4.2 What will happen to a population made up mostly of individuals that are past reproductive age? 4.2 What can you predict about a population with an age-structure diagram shaped like a pyramid? 4.2 Describe how you might use population distribution to find the sources of food or other resources used by a species. 4.2 Explain the significance of an age-structure diagram in which the bars are short along one side and long on the opposite side. 4.2 How is a population’s size related to its’ well being? 4.3 What determines a population’s growth rate? 4.3 What is the growth rate equation? Be able to use it. 4.3 What is natality? 4.3 What is mortality? 4.3 What does survivorship 4.3 Describe organisms curves show? mortality that have a type 1 survivorship curve. 4.3Describe organisms 4.3Describe organisms mortality that have a type 2 mortality that have a type 3 survivorship curve. survivorship curve. 4.3 Which type of survivorship curve describes populations whose mortality is highest at young ages? 4.3 What is immigration? How does it affect the populations size? 4.3What is emmigration? How does it affect the populations size? 4.3 Define migration. How does it affect a populations size? 4.3 Describe exponential growth. 4.3 Describe logistical growth. 4.3 What is carrying capacity? Where is it on a graph? 4.3 How do limiting factors affect the populations size? 4.3 Which type of growth is shown most often in nature? Why? 4.3 What are density dependent factors? Give an example. What are density independent factors? Give an example. 4.3 What is biotic potential? 4.3 What is gestation time? How does it affect a What is generation time? population? How do these factors affect a population? Lab: Describe how to Lab: Describe how to perform Random Sampling perform mark and recapture. Case Study: Why was the disappearance of the Golden Toad odd? Case Study: Why did the Golden Toad’s population become decimated so quickly and eventually become extinct?
