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.

Ecosystem RolesProducer Consumer Decomposer
Make their own food Consumes other organisms for food
Break down dead organisms
Autotrophs Heterotroph Heterotroph
Plants, some algae Bears, Lions, Insects Bacteria, fungi
Heterotroph Family…….the Vores!
Herbivore Eats plants
Carnivore Eats animals (meat)
Omnivore Eats plants and animals
Detritivore Eats dead organisms

Major relationships in ecosystemsPredation Competition Cooperation Symbiosis
When one speciesuses another for food
Predator eats prey
Helps maintain healthy prey population

Cooperation
Cooperation is an interaction in which organisms work in a way that benefits
them all.

Relationship Scenarios
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.
