Study Notes
Ecological Niche
- A species' role in its ecosystem, including what it eats, what eats it, and how it behaves.
- No two species occupy the same niche.
- Producers and consumers obtain energy from different sources.
- Consumers are categorized by what they eat (herbivores, carnivores, omnivores, scavengers).
Food Chains
- Show the feeding relationships among organisms.
- Example: Squirrel eats seeds, weasel eats squirrel, goshawk eats weasel.
- Energy flows through the chain.
- Energy is lost at each level.
Trophic Levels
- Producers (1st level) are photosynthetic organisms.
- Primary consumers (2nd level) eat producers
- Secondary consumers (3rd level and up) eat primary consumers.
- Energy pyramids show how energy decreases at higher trophic levels.
Terrestrial Biomes
- Terrestrial ecosystems are mainly based on the climate.
- Multiple types of biomes exist on Earth.
Modern Agriculture
- Many foods consumed are not native to Canada.
- Agroecosystems differ from natural ecosystems.
- Agroecosystems have uniform abiotic features (less biodiversity) and are more intensely used by humans.
- Require human maintenance.
- Monocultures decrease biodiversity.
- Pests are consumers of crops in agricultural environments.
Acid Precipitation
- Impacts aquatic ecosystems by decreasing pH values.
- Impacts soil by dissolving metals necessary for plant growth.
- Impacts forests by weakening trees, making them more vulnerable.
- Impacts the Canadian economy.
