PREDATOR/PREY

GOAL:  
Role-play various organisms in a food web to learn about the complexities of predator/prey relationships and the movement of energy through the trophic levels.   



OBJECTIVES:

·Gain a better understanding of predator prey relationships in nature.

·Develop an appreciation for organisms’ competition for survival in the wild.

·Learn how energy travels through the food chain.

·Develop an awareness of how introduced toxins and nutrients can affect the food chain.



CONCEPTS/TOPICS:     

·Predator/Prey Relationships
·Trophic levels
·Bio-magnification
·Energy flow
·Populations
·Toxins
·Natural mortality
·Habitat loss
·Food web
·Food, water, shelter, air, space



After completing this lesson the aim is for students to be able to:

·Define both predator and prey and give several examples of each.

·Create a food chain using organisms from the forest environment.

·Describe how energy flows through the food chain.  

·Define bio-magnification and name a chemical that creates environmental concerns due to its movement through the food pyramid.

·Name two factors that can affect population size.

·List the five basic needs of living organisms in order to survive over time.
