Study Notes
Key Ecological Concepts
- Biotic Factors: Living components of an environment (plants, animals, bacteria).
- Abiotic Factors: Non-living components of an environment (sunlight, water, air, soil).
- Species: Groups of similar organisms that can reproduce and create fertile offspring (e.g., cats, oak trees).
- Population: All the members of a species living in a specific area (e.g., all deer in a forest).
- Community: All the different species living and interacting in a particular area (e.g., animals, plants, insects in a pond).
- Ecosystem: A community of living organisms interacting with their physical environment (e.g., a coral reef, a desert).
- Ecology: The scientific study of interactions between organisms and their environment.
Evolutionary Processes
- Natural Selection: The process where organisms better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits.
- Niche: The specific role or function of an organism within its ecosystem (e.g., a bee pollinating flowers).
Species Interactions
- Predator: An animal that hunts and kills other animals for food (e.g., a lion).
- Prey: An animal that is hunted and eaten by a predator (e.g., a rabbit).
-
Symbiosis: A close, long-term relationship between two different species, where at least one benefits.
- Parasitism: One species (parasite) benefits, while the other (host) is harmed (e.g., a tick on a dog).
- Mutualism: Both species benefit from the interaction (e.g., bees and flowers).
- Commensalism: One species benefits, and the other is neither harmed nor helped (e.g., birds nesting in trees).
- Parasite: The organism that benefits in a parasitic relationship (e.g., a flea on a cat).
- Host: The organism that is harmed in a parasitic relationship (e.g., a dog with fleas).
Feeding Relationships
- Food Web: A complex network of interconnected food chains, showing the flow of energy and nutrients through an ecosystem.
- Consumer: An organism that obtains energy by consuming other organisms (animals).
- Herbivore: A consumer that eats only plants (e.g., a cow).
- Carnivore: A consumer that eats only meat (e.g., a wolf).
- Omnivore: A consumer that eats both plants and animals (e.g., a bear).
- Autotroph: An organism that produces its own food using sunlight or chemicals (e.g., plants, algae).
