Endangered: Leatherback sea turtle (Dermochelys coriacea)
Kingdom: Animalia
Class: Reptilia
Order: Testudines
Family: Dermochelyidae
The leatherback is the largest, deepest diving, & most migratory/wide ranging of all sea turtles. Adult leatherbacks can reach ft in length & lbs in weight.

2. Do Now: May 14th
Place these levels of organization in order from smallest  largest: biosphere, population, ecosystem, organism
Give 1 example of a biotic factor & 1 example of an abiotic factor.
Is biodiversity good for an ecosystem? Why or why not?

3. Habitat vs. Niche Habitat: place/”address” where organism lives
Niche: species’ role/”job” in its community
E.g., my habitat is Swansboro HS; my niche in this habitat is a biology teacher

4. Limiting Factor
Biotic or abiotic factor that restricts growth or amount of orgs in a specific environment
Examples:
Water, food, space

5. Producer vs. Consumer Autotroph: Start of food chain Heterotroph:
Make own food
Photosynthesis or chemosynthesis
Start of food chain
Heterotroph:
Get food from others
4 Types:

6. 1. Herbivore
“Primary” consumer
Eats plants only

7. 2. Carnivore “Secondary,” “Tertiary,” or “Quaternary” consumer
Eats meat only
Predator: hunts & kills
Scavenger: feeds on already dead orgs

8. 3. Omnivores:
Eat both plants & animals

9. 4. Decomposer Break down detritus (dead, decaying orgs) outside cells
Absorb nutrients through cell wall
E.g., bacteria & fungi

10. Trophic Levels
Feeding levels in energy transfer along food chain

11. Trophic Pyramid  trophic level=  individuals, energy, & biomass
Biomass: amount of organic matter
Only 10% passed up to next level
Other 90% converted to unusable forms (e.g., body heat)

12. Food Chain vs. Food Web Simple, single energy flow
1 feeding relationship
BOTH:
Arrow points in direction of energy flow
Interdependent: when 1 pop changes, ALL pops change
Complex energy flow in many directions
Many feeding relationships

13. Food Web Poster Materials for each group:
1 set of pics (grassland, tropical rainforest, or temperate forest)
Scissors
Glue
Colored pencils/markers
1 large piece of paper/poster

14. Food Web Poster Create food web using provided images (4pts)
Draw 2 original pictures AND the sun (3pts)
Label each picture w/ 2 pieces of info: (8pts)
Autotroph or heterotroph AND
Producer, Primary consumer, Secondary consumer, Tertiary consumer, or Decomposer
Link pictures w/ arrows pointing in direction of energy flow (4pts)
