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

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

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

• 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

• 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)

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.
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.
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.
