Ecological Organization Ecology - relationships between organisms and their environment
9
Characteristics of Ecosystems Requirements –Constant flow of energy from the sun –Cycle of materials Abiotic Factors of Ecosystems (nonliving)Abiotic –Light, temperature, water, soil, gases, pH –Also called limiting factors Biotic Factors of Ecosystems (living)Biotic –Trees, animals, fungi, bacteria
10
Biotic Vs. Abiotic
11
Biotic Factors
12
· Organisms that look alike and can mate among themselves. Species
13
Population all members of a species living in a particular location
14
Community interacting populations (white tail deer, maple trees, coral reef, etc.)
15
Ecosystem members of a community and their physical environment The organisms plus: –Water –Temperature –Sunlight –pH
16
Community How does a community differ from a population? An ecosystem?
17
Habitat vs. Niche Habitat –environment in which an organism lives Niche – the role a species fills in its habitat (what it eats, where it lives)
18
Niche coyote wolf NC State Bird What is this bird? NC State Mammal
19
Symbiotic Relationships - living together in close association Mutualism –both organisms benefit Parasitism – 1 organism benefits, the other is harmed

Nitrogen Fixing Bacteria are an example of mutualism! Nitrogen Fixation – Seven Wonders of the Microbe WorldNitrogen Fixation – Seven Wonders of the Microbe World
22
Mutualism Lichens – algae And fungi
23
Figure 31.17 Anatomy of a lichen
24
A remarkable 3-way mutualism appears to have evolved between an ant, a butterfly caterpillar, and an acacia in the American southwest. The caterpillars have nectar organs which the ants drink from, and the acacia tolerates the feeding caterpillars. The ants appear to provide some protection for both plant and caterpillar. Mutualism
25
Figure 28.x1 Trichonympha These guys are found in the digestive tract of termites – they digest cellulose for termites!
26
Mutualism: Sea Turtles and Yellow Tang The yellow tang eat algae off the turtle!

Parasitism - Tapeworm

Parasites – Bed bugs http://www.youtub e.com/watch?v= WfKCcSPCOQo Pesticide resistance contributes to the challenge of controlling this pest.
30
Tomato Horn Worm This is the moth that the tomato horn worm becomes if it doesn’t get parasitized! This is the Braconid wasp that parasitizes the caterpillar.

List the various symbiotic relationships Zombie snails Reef Symbiosis
33
Complex Symbiotic Relationships Zombie Ants Parasitic Wasps Be able to discuss the interactions of this complex symbiotic system.
34
Nutritional Relationships Autotrophs – make their own food (plants) –Also called producers
35
Nutritional Relationships Heterotrophs –eat autotrophs and other organisms –Also called consumers –Examples are animals, fungi, protists, and bacteria Types of Heterotrophs: –Herbivores eat plants –Carnivores eat animals –Predators »hunt –Scavengers »feed on animals they haven’t killed –Omnivores eat plants and animals

37
Energy Flow Relationships Producers – plants (autotrophs) Consumers – animals (heterotrophs) Primary – eat producers Secondary – eat primary consumers Tertiary – eat producers and primary consumers Decomposers –Break down dead organisms (bacteria and fungi)
38
Brook Trout – Why are they endangered? Red-cheeked Salamander – Why are they endangered? Hemlock and Fraser Fir Trees – What is happening to them? Reintroduction of the Elk in the Smokies – has it been successful? Migratory Songbirds and calcium limitations – What is happening to them? Indiana Bat – Why are they endangered? Carolina Northern Flying Squirrel – Why are they endangered? Spruce-Fir Moss Spider – Why do we care that they are endangered? Reintroduction of Smoky Madtoms – has it been successful? Reintroduction of Peregrine Falcons – has it been successful?
39
PBL Task #1 Use as many of the Ecology terms we just learned to discuss your topic with your partner. Relate this discussion to the Smoky Mountains and climate change as best you can. Pay attention to ground-level ozone and acid rain as you do your research. Here are some things I am looking for: –What community do they live in? Please show a picture of their community. –What is their niche in their habitat? –Do they have a symbiotic relationship with any other organisms?
40
PBL Task #1 –The next 2 bullets are answered according to the type of organism you have chosen: Heterotrophs: –Tell me about their nutritional relationships…which type of heterotroph are they? –Discuss their main food source –If anything happening to their main food source that would make them threatened/endangered? Autotrophs: –Is their population declining or rising? –Give reasons why. –Give me any other information you feel is important to this point.
41
PBL Task #1 - continued Type this information into a presentation document….it can be a google presentation, a Prezi or something else that your group chooses. I would recommend that you use some type of sharing software so that you will be able to work on it at your respective homes. Use reliable internet sources and be sure to copy and paste the links into your document.
42
Schoology Ecology Assignments Make sure you understand ALL of the concepts you have just covered in this module. If you do not, please go back through it and ask any questions needed. You can also check out the Reviewing Biology – Ecology Folder on Schoology. See the Part 1 – Characteristics of Ecosystems File. You can then do Schoology Ecology Assignment #1 on Characteristics of Ecosystems You can then begin Ecology Module #2
