Ecology
• Ecology: the study of relationships between living organism, and their interaction with their environments.
• Biosphere: The portion of the earth that supports life.

Biotic and Abiotic Factors
• Biotic Factors: The living factors in an organism’s environment.
• Abiotic Factors: The non-living factors in an organism’s environment.

organism
• The lowest level of ecological classification is the single organism.
• (Example: one single fish)

Population
• A population is all the individuals of a single species that share the same geographic location at the same time.
• (example: a school of fish)

Biological Community
• Community: A group of interacting populations that occupy the same geographic area at the same time.

Ecosystem
• Ecosystem: includes a community and all the abiotic factors that effect it.

Biome
• Biome: a large group of ecosystems that share the same climate and have similar types of communities.
• (Example: a marine biome)

Habitat and Niche
• Habitat: the area where an organism lives.• Niche: the role or position that an organism
has in it’s environment. (it’s job).

Community Interactions
![Page 14: Objectives: 1. Explain the difference between abiotic and biotic factors. 2. Describe the levels of biological organization 3. Differentiate between an](https://reader033.vdocuments.site/reader033/viewer/2022051517/56649dac5503460f94a9b96e/html5/thumbnails/14.jpg)
Community Interactions
• Competition: occurs when more than one organism uses a resource at the same time.
• Competition for food, water, space, light, and mates.
• Predation: The act of one organism consuming another organism for food.
![Page 15: Objectives: 1. Explain the difference between abiotic and biotic factors. 2. Describe the levels of biological organization 3. Differentiate between an](https://reader033.vdocuments.site/reader033/viewer/2022051517/56649dac5503460f94a9b96e/html5/thumbnails/15.jpg)
Community Relationships Continued
• Symbiotic relationship: A close relationship that exists when two or more species live together.
![Page 16: Objectives: 1. Explain the difference between abiotic and biotic factors. 2. Describe the levels of biological organization 3. Differentiate between an](https://reader033.vdocuments.site/reader033/viewer/2022051517/56649dac5503460f94a9b96e/html5/thumbnails/16.jpg)
Three types of Symbiotic Relationships
• Mutualism: when the two or more organisms both benefit from the relationship.
• Commensalism: a relationship when one organism benefits and the other organisms is neither helped nor harmed.
• Parasitism: a relationship when one organism benefits at the expense of another organism.
