PRESENTATION OUTLINE
Ecological Organization
Learning about how organisms are arranged in the environment
This overview of ecological organization is very basic and details how organisms are grouped in our environments and key vocabulary terms.

Organism
- Any living thing
- Examples: a plant, an animal, a protist, a fungus, a bacteriun
- Belong to one of the six kingdoms -- Plants, Animals, Protists, Fungi, Eubacteria, and Archaebacteria
- Smallest grouping
An organism is any living thing. Any living thing could be a type of plant or animal or even a type of bacteria, protists, or fungus. The term organism refers to the simplest grouping of one living thing only.

Population
- Definition: A population is a group of individuals of one species or of one kind.
- Examples include:
- a group of humans
- a group of butterfly bushes
- a group of cattle
Multiple organisms of the same species make up a population. The term species refers to organisms that are the same kind. For example, humans have a scientific name of Homo sapien. The second word of the scientific name, which is sapien, is the species.

Community
- A community is a group of organisms of different species all living together in one environment.
- This is a bigger grouping than a population.
- Example: All of the cattle in an area, all of the horses in an arrow, grass, oak trees, dandelions
A community is a larger grouping than a population and generally groups all of the living things together into one environment. This grouping combines organisms from all species and all kingdoms.

Ecosystem
- An ecosystem consists of all of the living features and the nonliving features of an environment together.
- This is the largest grouping among the terms organism, population, community, and ecosystem.
- Example: Coral reef ecosystem -- with coral, star fish, fish, sand, water, oxygen, rocks
Finally, the largest grouping of the four terms is an ecosystem. An ecosystem consists of living things and nonliving features of an environment. An ecosystem combines the community with all of the nonliving parts, like rocks, soil, sand, oxygen, water, etc.

ecological organization
- Organism (smallest)
- Population
- Community
- Ecosystem (largest)
Finally, this slide is just an overview of the ecological organization discussed in this presentation. From smallest to largest grouping, organism, population, community, then ecosystem would be the proper arrangement.
