Ecosystems (Part 1) Notes
![Page 2: Ecosystems (Part 1) Notes. Biotic Definition: A living component of an ecosystem. Examples: –Trees –Grass –Birds –Humans –Flowers.](https://reader033.fdocuments.us/reader033/viewer/2022061412/5697bfe21a28abf838cb42ab/html5/thumbnails/2.jpg)
Biotic
• Definition: A living component of an ecosystem.
• Examples:– Trees– Grass– Birds– Humans– Flowers

Abiotic
• Definition: A non-living component of an ecosystem.
• Examples:– Clouds– Water– Temperature– Air– Rocks– Minerals

Producer
• Definition: An organism that makes its own food using sunlight.
• Examples:– Trees– Flowers– Plants

Consumer
• Definition: An organism that eats other organisms to get energy.
• Examples:– Humans– Goats–Wolves

Decomposer
• Definition: An organism that breaks down dead organisms to get energy.
• Examples:– Bacteria–Worms– Fungi

Population
• Definition: A group of individuals of the same species living in a specific area.
• Examples:– A group of jellyfish living in the same
area of the ocean– A group of wolves living together in
Alaska

Community
• Definition: All of the populations of species living and interacting together in the same habitat.
• Examples:– Jellyfish, sharks, and plankton all living
together and interacting in the same ocean– Wolves, deer, and bears all living together
and interacting in Alaska

Ecosystem
• Definition: A community of organisms and their abiotic environment.
• Examples:– Jellyfish, sharks, plankton, water, and
temperature–Wolves, deer, bears, rocks, clouds,
temperature

Influences on Population Size
• Food supply• Temperature• Rainfall• Disease• Pollution• Invasive (new) species• Human development
![Page 14: Ecosystems (Part 1) Notes. Biotic Definition: A living component of an ecosystem. Examples: –Trees –Grass –Birds –Humans –Flowers.](https://reader033.fdocuments.us/reader033/viewer/2022061412/5697bfe21a28abf838cb42ab/html5/thumbnails/14.jpg)
Indirect Causes of Population Change
• Changes in rainfall or average temperature can indirectly influence plant populations, which can indirectly influence animal populations that eat those plants for food.

Invasive Species
• New (invasive) species in an ecosystem can influence changes in populations.
• Zebra mussels and purple loosetrife cause changes in the populations of native species.
