Relier Pairs Systems and Models (part 3) - Review for Ecology UnitVersion en ligne assignment par Benjamin D Morgan 1 How does the number of predators affect the prey population? The dependent variable is... 2 Types of models 3 Closed System 4 Flows within 5 Open System 6 How does the number of predators affect the prey population? The controlled variable is... 7 Model 8 System Function 9 System Interaction 10 System Importance 11 Energy Transfers 12 Model Importance 13 How does the number of predators affect the prey population? The independent variable is... 14 Energy Transformations 15 Actual System Systems effect other systems. Objects and energy will leave one system and enter another system. The system or object under study. Not a representation Prey population When matter cannot enter or leave a system, but energy can enter/leave Autotroph population When matter can enter and leave a system. Predator population To help us understand systems better by allowing us to study it, perform experiments, etc on a smaller version of the system When matter or energy moves inside of a system 3D smaller items, computer simulations, diagrams, pictures. When energy moves from one system (object) to another system (object) For tracking energy and matter flows so that we can better understand the concept What a system is designed for...it's job/role Energy can change from one type of energy to another type of energy when it interacts with a system Representation of the actual system
