State Standards:
5: LS.1: Organisms perform a variety of roles in an ecosystem.
5: LS.2: All of the processes that take place within organisms require energy.
Objectives
At the end of the program, student will be able to:
· Define and identify several ecosystems throughout the world and Ohio.
· Articulate the four major essentials for life that living organisms need to survive in an ecosystem.
· Explain the basic process of photosynthesis and identify its purpose in an ecosystem.
· Understand that all life needs a constant energy flow.
· Identify the difference between a producer, consumer, and decomposer.
· Identify and understand a trophic pyramid and the loss of energy from one consumer level to the next. (primary consumer, secondary consumer, tertiary consumer)
· Distinguish the different types of consumers, i.e. herbivore, omnivore, and carnivore.
· Recognize that energy flow is a cycle and can be replenished in part by scavengers and decomposers back into soil.
· Identify and define dynamic relationships within ecosystems, i.e., symbiotic relationships (mutualism, commensalism, parasitism, competition, and predation).
· Distinguish between an introduced and invasive species and how this affects the flow of energy and relationships in an ecosystem.
· Distinguish between a threatened and endangered species
