Bellwork1. Look at the 8 levels of organization on the back of your notetaker from yesterday. Come up with your own real life version for each level (see my example below- you can use “Earth” )

Biosphere = EarthEcosystem = RainforestCommunity = trees, birds, and bugs in the areaPopulation = all of the toucansOrganism = a single banana treeTissue/Organ = A panther’s heartCell = A brain cellAtom/Molecule = H2O

Example!

Energy Flow & Roles of Organisms(notes on lined paper)

Autotrophs

Autotroph = organism that makes food for itself (producer)

“Self” “food”

Talk to Your Partner

Based on the definition we just wrote down, what are some examples of autotrophs?

Autotrophs

Autotroph = organism that makes food for itself (producer)

-Ex: plants & some bacteria

“Self” “food”

Heterotrophs

Heterotroph = organism that eats other organisms (consumers)

“Different” “food”

I must be a heterotroph, since I

can’t synthesize these!

Heterotrophs

Heterotroph = organism that eats other organisms (consumers)

-Examples: animals, fungus, bacteria

“Different” “food”

Try this! (5 mins)At your lab table:

Work as a group to quickly sort the cards & use arrows to show which direction energy is flowing

Example:

2 Big Categories of OrganismsMake a T-chart

Autotrophs/ Heterotrophs/ Producers Consumers

There are two types of autotrophs/producers

Autotrophs

1. Phototroph : use energy from sun to make food (photosynthesis)

Autotrophs

2. Chemotrophs : use energy from chemicals to make food

Ex- Bacteria in deep sea vents

There are many types of heterotrophs

List as many types as you canHint: A cow is one type

Heterotrophs

1. Herbivores : eat ONLY plants

Heterotrophs

2. Omnivores : Eat BOTH plants & animals

Heterotrophs

3. Carnivores : eat ONLY meat

Heterotrophs

4. Scavengers: feed on dead organisms• Ex. – Vultures, Shrimp, Mealworms!

Heterotrophs

5. Decomposers : Absorb dead materials/waste & break them down into fertilizers for plants

• Ex. – bacteria, mushrooms

Try this! (Part 2)

Add organism terms to the cards at your lab table

Example:

Omnivore

Closure 1. On back of notes- Draw a simple food chain for your critter, with at least 5 organisms.

2. Label each organism with vocab- herbivore, phototroph, etc.

3. When finished, put together your critter & drop it off in the front basket
