2. 8.L.3 Understand how organisms interact with and respond to the biotic and abiotic components of their environment 8.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)

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

27. Major relationships in ecosystems PredationCompetitionCooperationSymbiosis When one species uses another for food Predator eats prey Helps maintain healthy prey population The struggle between individuals or different populations for a limited resource Compete for: Food Shelter Mates Example:Example

37. Major relationships in ecosystems PredationCompetitionCooperationSymbiosis When one species uses another for food Predator eats prey Helps maintain healthy prey population The struggle between individuals or different populations for a limited resource Compete for: Food Shelter Mates An interaction in which organisms work in a way that benefits them all. Example:Example

38. Cooperation

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

42. Major relationships in ecosystems PredationCompetitionCooperationSymbiosis When one species uses another for food Predator eats prey Helps maintain healthy prey population The struggle between individuals or different populations for a limited resource Compete for: Food Shelter Mates An interaction in which organisms work in a way that benefits them all. A relationship between individuals of two DIFFERENT species that live together in a close relationship. Mutualism + + Parasitism + - Commensalism + 0 Example:Example

48. + --

55. Commensalism

56. Relationship Scenarios Identify each relationship as: Competition Cooperation Predator/prey (who is who) Symbiosis (what type: M, C, P)

57. Identify: Producer, consumer, autotroph, heterotrophs, organisms, population, community, biotic, abiotic, cooperation, competition, predator/prey, describe habitat, describe niche of one organism. https://www.youtube.com/watch?v=IHssoS3whxM https://www.youtube.com/watch?v=2jXxtQRy47A https://www.youtube.com/watch?v=BXCvLzDNWz0

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.
