Park Analysis 7

8.L.3 Understand how organisms interact with and respond to the biotic and abiotic components of their environment8.L.3.1 Explain how factors such as food, water, shelter, and space affect populations in an ecosystem. 8.L.3.2 Summarize the relationships between producers, consumers and decomposers including the positive and negative consequences of such interactions including

– Coexistence and cooperation– Competition (predator/prey)– Parasitism– Mutualism

8.3.3 Explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide, and oxygen)

TLW identify ecosystem relationships using scenarios and videos, then summarize how they impact each other and the ecosystem thru a quick write.

Identify each relationship as:CompetitionCooperationPredator/prey (who is who)Symbiosis (what type: M, C, P)

Identify:Producer, consumer, autotroph, heterotrophs, organisms, population, community, biotic, abiotic, cooperation, competition, predator/prey, describe habitat, describe niche of one organism.

CHOOSE ONE, PART A:

• Describe the habitat and niche of the Yellowstone Park wolves.

• Describe the habitat and niche of the Yellowstone Park elk.

CHOOSE ONE, PART B:

• Explain the re-introduction of wolves into Yellowstone Park changed the niche of the Elk.

• Compare and contrast the niche of two populations in Yellowstone park that occupy the same habitat.
