Organisms

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

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• Biology Song

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 QuickTime™ and a

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 plantsB. Carnivores = Organisms that eat only animalsC. Omnivores = Consumers that eat both plants and animalsD. Scavengers = Feed on the bodies of dead organisms

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)

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.
