1. Organisms
I will be able to properly identify and describe the 3 types of organisms in an ecosystem!

2. Standards 6th Grade Science; Life #2 7th Grade Science; Life #2

3. QW5: What is an Organism
Organism = a free living unit of life/ Any Living Thing
Examples: Amoeba (single celled organism) Elephant (multi-cellular organism)
Both of these organisms need energy and food to stay alive
Individual = one single species in a specified area

4. What do organisms need to be considered alive?
7 Characteristics of Life;
1. Made of Cells
2. Energy/ Food and Water
3. Exchange Gas/ Breath
4. Respond to their environment
5. Produce Waste
6. Grow
7. Reproduce

5. 3 Main Types of Organisms
1. Producers =
A: organisms that can make their own food
Photosynthesis =
Sunlight + Water + CO2 = Glucose and O2
Trees, Grass, Flowers

6. 3 Main Types of Organisms
2. Consumers =
A: An organism that obtains energy by feeding on other organisms
4 Types of Consumers;
A. Herbivore = Consumers that eat only plants
B. Carnivores = Organisms that eat only animals
C. Omnivores = Consumers that eat both plants and animals
D. Scavengers = Feed on the bodies of dead organisms

7. 3 Main Types of Organisms
3. Decomposers =
A: organisms that break down waste and dead organisms returning the raw materials to the environment
Examples: Bacteria and Fungi (Molds and mushrooms)

8. Milkweed Bugs Bugs have the same structure as most other insects:
Six legs, three body parts (head, thorax and abdomen) and two antennae.
Bugs do not have mouths. They have a proboscis (beak) for sucking fluids.

9. Milkweed Bugs
Our Milkweed bugs will be eating raw, unshelled sunflower seeds. Milkweed bugs are born from eggs and the babies are called nymphs.
As they grow they go through a periodical molt where they shed their skin.
To tell the difference from a male and a female you will need to look at their bellies. Solid black bands equal a male and the two dotted one is the female.

10. Why do I Need to Learn This?
In order to live some basic needs need to be met.
Finally, we learn to care for organisms that are different from ourselves.
