Study Notes
- Topic: AP Environmental Science video notes covering ecosystems and species interactions
- Ecosystem components: Individual (single organism), Population (group of same species), Community (all living organisms in an area), Ecosystem (living and nonliving components), Biome (large area with similar climate)
- Species interactions: Competition (lose-lose situation, fighting over shared resources), Predation (positive for predator, negative for prey), Mutualism (beneficial for both species), Commensalism (one benefits, other not affected)
- Types of predators: Herbivores (e.g., giraffe eating plants), True predators (e.g., lion eating giraffe), Parasites (draw energy from host), Parasitoids (lay eggs inside host)
- Symbiosis: Two different species living closely together long-term, can be mutualistic, commensal, or parasitic
- Mutualism examples: Coral reef ecosystem (coral and algae), Lichen (fungi and algae living together)
- Competition: Resource partitioning reduces competition, includes temporal, spatial, and morphological partitioning
- Resource partitioning examples: Temporal (wolf and coyote hunt at different times), Spatial (different grass roots depths), Morphological (fair and ermine have different jaw sizes)
- Objective: Describe an environmental concept and process, practice skill with FRQ on identifying organisms competing for shared food resource and how resource partitioning can reduce competition.
