Study Notes
Introducing Ecosystems
- Ecosystems encompass all living organisms in a region, interacting with each other and their non-living environment.
- Ecosystem components are interconnected; changes in one part can impact others.
Types of Ecosystems
- Natural Ecosystems: Ecosystems formed naturally over time due to environmental factors.
- Examples: meadows, forests, ponds, streams.
- Artificial Ecosystems: Ecosystems designed and maintained by humans.
- Examples: parks, farms, zoos, schoolyards.
Types of Natural Ecosystems
- Aquatic Ecosystems: Ecosystems existing within bodies of water.
- Examples: oceans, ponds, rivers, lakes, marshes, swamps, streams.
- Terrestrial Ecosystems: Ecosystems existing on land.
- Examples: rainforests, mountains, grasslands, deserts, tundra, urban/artificial.
Examples of Aquatic Ecosystems
- Ocean
- Pond
- River
- Lake
- Marsh
- Swamp
- Stream
Examples of Terrestrial Ecosystems
- Rainforest
- Mountain
- Grassland
- Desert
- Tundra
- Urban/Artificial
Levels of Organization in an Ecosystem
- Biodiversity: The number of different species within an ecosystem.
- Ecology: The study of how species interact with each other and their environment.
- Scientists study ecology at various levels: individual, population, community, ecosystem, and biosphere.
Levels of Organization in Detail
- Individual: Any living organism.
- Population: All individuals of a single species in the same area.
- Community: All the different populations in the same area.
- Ecosystem: All living organisms in a community (biotic) interacting with the environment (abiotic).
- Biosphere: Includes all ecosystems on Earth.
Habitat and Ecological Niche
- Habitat: The place where an organism lives.
- Ecological Niche: The role a species plays within its environment, encompassing its interactions with other species and its environment.
- No two species have the exact same niche. This includes what they eat, where they live, and how they behave.
Niche
- Every member of a community gathers food in a unique way.
Sustainability
- Most ecosystems are sustainable, meaning they can maintain natural conditions without interruption, and prevent the loss of biodiversity in the long term.
