Ecology Review Interactions Among Living Things #20 Name _________________________ We are going to take about 5 class periods to review the ecology concepts you learned in 6th grade. There are 4 ecology standards that will be part of this review: 13. Give examples of ways in which organisms interact and have different functions within an ecosystem that enable the ecosystem to survive. 14. Explain the roles and relationships among producers, consumers, and decomposers in the process of energy transfer in a food web. 15. Explain how dead plants and animals are broken down by other living organisms and how this process contributes to the system as a whole. 17. Identify ways in which ecosystems have changed throughout geologic time in response to physical conditions, interactions among organisms, and the actions of humans. Describe how changes may be catastrophes such as volcanic eruptions or ice storms. ***************************************************************************** This PowerPoint is to review Standard #13 Slide 1: Interactions Among Living Things: Competition A. Definition- COMPETITION: the struggle between organisms to survive as they attempt to use the ____________________________________________________. B. Limited resources: ___________________ ____________________ __________________ Slide 2: Oh’Deer (if time) Slide 3: Interactions Among Living Things: Predation A. Definition = PREDATION= An interaction in which one organism kills another _______________ B. Definition =PREDATOR= The organisms that __________________________ C. Definition = PREY = the organisms that __________________________ Slide 4: A. Predator Adaptations: B. Prey Adaptations - camouflage __________________________ - Speed - Poison ________________________ - Claws _________________________ -warning colors _________________________ - sharp teeth _____________________ -mimicry __________________________ - stingers ________________________ -false coloring ________________________ - night vision _____________________ _______________________ -protective coverings ____________________ - echo location ____________________ Slide 5: Pictures of adaptations Slide 6: Owl Eyed Moth (false coloring) Slide 7: Monarch Butterfly (mimicry) Slide 8: Interactions Among Living Things: Symbiosis = “Living Together” A. Definition = SYMBIOSIS: a close relationship between two species that benefits _______________ _______________________________________________ B. 3 Types of Symbiosis: mutualism, commensalisms, parasitism Slide 9: Mutualism A. Definition = MUTUALISM = The close relationship where ________________organisms benefit. B. Example – Ants and Acacia Tree Slide 10:Mutualism continued A. Plover in crocodile mouth feeds on leeches Slide 11:Commensalism A. Definition = COMMENSALISM= Relationship where one species _________________________ and the other species is neither __________________________ nor _________________________. B. Example- barnacle and scallop shell Slide 12:Parasitism A. Definition = PARASITISM= Relationship where one species lives ________ or ________ another species and _______________________. B. Parasite= the organism that __________________________. C. Host= the organism that _________________________. Slide 13:Parasitism Example - Tick in Dog’s Ear A. Host = _______________ B. Parasite = ________________ Slide 14:Parasitism Example- Sea Lamprey A. Host = _______________ B. Parasite = ____________________ Slide 15: Parasitism Example- Strangler Fig Tree
