Presentation Transcript

  1. Warm Up • Thursday, February 14, 2013 • What elements are found in carbohydrates? • What elements are found in proteins?

  2. Ecology #1

  3. Objectives • Categorize ecology terms for describing the different stages of an ecosystem. • Describe the difference between abiotic and biotic factors. • List real world examples of autotrophs and heterotrophs.

  4. Ecology Ecology= study of interactions among organisms & their surroundings (environment)

  5. Species = group of organisms that can breed & produce fertile offspring • Example: Cave Shrimp • Non-example: Mules

  6. Question? • Why isn’t a mule an example of a species?

  7. Population = group of organisms that belong to the same species & live in the same area. • Example: group of cave shrimp in a single cave

  8. Community = group of different populations that live together in a defined area • Example: cave shrimp, isopods, amphipods, & bacteria (in an underwater cave)

  9. Ecosystem = Collection of all organisms that live in a particular place, together w/ non-living or physical environment. • Example: Cave System in Bermuda

  10. Biome = group of ecosystems that have the same climate & similar dominant communities • Example: desert, tundra, rain forest.

  11. Biosphere = part of the earth & its atmosphere in which living organisms exist or that is capable of supporting life • Made up of: • land • water • air (atmosphere)

  12. Put it all together! • Draw a series of 5 circles: smallest in the center & largest on the outside. Put the following terms in the circles to show how they fit together. • Terms: • Biome • Biosphere • Community • Population • Ecosystem

  13. Putting it all together

  14. Biology = study of life Latin Root: Bio = Life

  15. Biotic Factors = any living component that affects another organism • Examples: • Competitors • Predators • Prey • Disease (Bacteria)

  16. Abiotic Factors = physical or nonliving things that shape an ecosystem • Examples: • Soil • Weather • Light • Water

  17. Niche = ecological role & space an organism fills in its environment/ecosystem • Example: • Bee acts as a pollinator in its ecosystem

  18. Energy Sunlight = MAIN source of energy for life on Earth!

  19. Autotrophs = Organism makes own food for energy • Latin Roots • Auto = self • Troph = nutrition/energy • Examples: plants, algae, some bacteria • 2 types: 1) Chemoautotroph – make own food using chemicals. 2) Photoautotroph – make own food using light. • AKA PRODUCERS

  20. Heterotrophs =Organisms rely on other organism for food (eat other organisms) • Latin Roots • Hetero – different • Troph – nutrition/energy • AKA CONSUMERS • Example: mammals, birds, fish

  21. Carnivore = Organism eats only meat • Example: Lion

  22. Herbivore = organism eats only plants • Example: zebra

  23. Omnivore • Organisms eat both plants & animals • Example: Baboons

  24. Detritivore • Organisms eat dead or decaying matter • AKA Scavenger • Example: vulture

  25. Decomposer • Organisms that break down dead or decaying matter externally, then take it in. • Example: fungus

  26. Use those vocabulary words! • Provide a different example of each of the following on the next blank page: • Herbivore • Carnivore • Omnivore • Detritivore • Decomposer • Autotroph • Heterotroph Useadifferentcolorforeach!

  27. Warm Up • Friday, February 15, 2013 • What type of biomolecule is represented by the following image?

  28. Ecology #2

  29. Objectives • List the important levels in a food chain • Create a food web for a real world organism.

  30. Food Chain Heterotroph/3rd (tertiary)level consumer carnivore Heterotroph/2nd (secondary) level consumer omnivore Heterotroph/1st(primary) level consumer herbivore Autotroph/producer

  31. Trophic Levels = Energy levels in a food chain or food web • Each level receive ONLY 10% of the previous trophic level’s energy • INEFFICIENT!!!

  32. Time to think! • How much energy will the rabbit get from his meal? • How much energy will the lion get from his meal? • Why doesn’t the rabbit get 1000Kg of energy from the grass?

  33. Food Chain 0.1% Heterotroph/3rd(tertiary) level consumer carnivore 1% omnivore Heterotroph/2nd (secondary) level consumer Trophic levels 10% Heterotroph/1st(primary) level consumer herbivore 100% Autotroph/producer

  34. Create a Food Web • Select an organism you want to learn more about Determine what type of environment it lives in • Determine the predators and prey items in that environment • Draw the food web (Use names or pictures.) • List the producers. • List the primary consumers. • List the secondary consumers. • Label each animal as herbivore, carnivore or omnivore.

  35. Computer Log In • User name: • 1st 5 letters Last Name (lowercase), 1st 3 letters 1st Name (lower case), 000 • Example: malonbri000 • Password: • Student ID # • Lunch #

  36. Warm Up • Monday, February 18, 2013 1.What is the function of an enzyme? 2. What 3 letters do most enzymes end in?

  37. Ecology #3

  38. Objectives • Compare and contrast the different types of symbiotic relationships. • Give real world examples of the 5 different types of symbiotic relationships. • Determine the carrying capacity from a graph.

  39. Symbiotic Relationships • Symbiosis = any relationship btw 2 organisms that live closely together • 5 types……

  40. 1) Predation = interaction where one organism hunts & kills another • Predator – hunter • Prey – food • Example: • lion hunting zebra

  41. 2) Mutualism = relationship where both organisms benefit • Example: bees & flowers

  42. 3) Commensalism = relationship where 1 organism benefits & other is neither harmed or benefited • Example: whales & barnacles

  43. 4) Parasitism = relationship where 1 organism benefits & other is harmed • Example: • tick & dog • mosquito & human

  44. 5) Competition = relationship where 1 organism competes with another for food, shelter, mate, etc.

  45. Using the vocabulary: • Give an example from one of our ecosystems for each of the following terms. • Competition • Parasitism • Mutualism • Commensalism • Predation Useadifferentcolorforeach!

  46. Carrying Capacity = amount of life an ecosystem can support w/ its resources • Balance between life (reproduction) & death • Birth rate vs death rate

  47. Carrying Capacity What is the carrying capacity in this graph? Why is the purple line going up and down?

  48. Carrying Capacity Word Problem • Add title to Table of Contents • Turn to next blank page & add title • Write definition of carrying capacity (1st sentence on the front of the paper) • Answer Questions on the back of the paper in COMPLETE SENTENCES Question #1 – 2 sentences Question #2 – 3 sentences

  49. Warm Up • Tuesday, February 19, 2013 • Looking at the graph below, adding an enzyme to the reaction lowers the what?

  50. Objectives • Interpret a graph to determine the carrying capacity for a population. • Evaluate the resources available for a population to predict the future trends in a carrying capacity graph.
