1. Bell work Week
Biosphere: part of Earth in which life exists including land, water, and air atmosphere.
Ecosystem: collection of all the organisms that live in a particular place, together with their nonliving environment.
Population: group of individuals of the same species that live in the same area
Species: group of similar organisms that can breed and produce fertile offspring.
Community: assemblage of different populations that live together in a defined area.

2. Title of Notes: Ecology pg. 30 & 31 RS
Goal for lesson: write on self assessment worksheet
I can describe and give an example of the two types of organisms involved in an ecosystem.

3. Study of organisms and their surroundings.
Ecology
Study of organisms and their surroundings.

4. Levels of Organization

5. Producers (autotrophs)
Autotrophs (self-feeders), such as plants and algae, can capture energy from sunlight or chemicals and use that energy to produce food.

6. Photosynthesis (Producers)
Autotrophs use photosynthesis to produce food for themselves.
Using sunlight, water, and carbon dioxide, photosynthesis turns energy into food (carbohydrates such as sugars and starch)

7. Chemosynthesis (Producers)
Process by which some organisms use chemical energy to produce carbohydrates.

8. Consumers (heterotrophs)
Heterotrophs: Organisms that rely on other organisms for energy and food supply.
Herbivores: plant eaters
Some examples of herbivores are cows, caterpillars, and deer.

9. Consumers(heterotrophs)
Carnivores: meat eaters (other animals)
Some examples are snakes, dogs, and owls

10. Consumers(heterotrophs)
Omnivores: eat both plant and meat
Some examples are humans and bears

11. Consumers(heterotrophs)
Detritivores: consume dead plant and animal matter.
Some examples are mites, earthworms, snails, and crabs
The dead matter is collectively called detritus

12. Consumers(heterotrophs)
Decomposers: do not consume, but break down plant and animal matter into simpler compounds, which returns nutrients back into the soil.
Some examples are bacteria and fungi

13. Ecological pyramids
The amount of energy of matter in an ecosystem can be represented by an ecological pyramid. It shows relative amounts of energy or matter.
3 types of pyramids:
1. Energy pyramid
2. Biomass pyramid
3. Pyramid of numbers
