Biotic and Abiotic Population Factors

Open Ended

(Ringer)- If what happened in The Day After Tomorrow, where an ice age occurred in America, what do you predict will happen with the ecosystems? Think about energy flow in food webs and food chains.

Orientation

Objective of the lesson:
Use mathematical models to construct an explanation for population growth patterns and rates observed in ecosystems. Account for both density-dependent and density-independent factors in your explanation
Analyze data regarding exponential and logistic population growth patterns. Use the data to create mathematical models to make predictions regarding carrying capacity
Use a mathematical model to examine predator-prey interactions. Based on the model, construct an argument regarding the importance of predators in maintaining stability of prey populations
Use models to explain the impacts of types of symbiosis on the species involved in the relationship.
