Lesson Overview
Objective:
Students will analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem, using Webster’s salamanders as a case study.
Essential Question
How does resource availability impact the population dynamics of organisms within an ecosystem, specifically focusing on Webster’s salamanders?
What types of resources are essential for the survival and reproduction of Webster’s salamanders, and how do changes in these resources affect their populations?
How can analyzing and interpreting data on salamander populations provide evidence for the effects of resource availability on organisms and populations in an ecosystem?
What are some potential consequences of resource scarcity or abundance on Webster’s salamander populations, and how do these effects ripple through the ecosystem?
How do human activities, such as habitat destruction and pollution, alter the availability of resources for Webster’s salamanders, and what are the implications for their populations and the broader ecosystem?
