Ecological interdependence — definition?
Organisms rely on each other for survival.
Competition — effect?
Limits resources, affects populations.
Stable community — characteristic?
Constant populations, resilient to change.
Ecosystem — components?
Community + abiotic factors.
Abiotic factors — examples?
Light, temperature, moisture, soil pH, wind.
Biotic factors — examples?
Predators, food, competition.
Organism adaptations — types?
Structural, behavioural, physiological.
Material cycles — role?
Recycle nutrients, sustain life.
Food chain — start?
Producers (plants, algae).
Trophic level — transfer?
About 10% energy transfer.
Biomass — definition?
Mass of living material, energy store.
Energy transfer — efficiency?
Approximately 10% between levels.
Human impact — causes?
Habitat destruction, pollution, resource overuse.
Biodiversity — importance?
Supports stability, resilience, resources.
Conservation — methods?
Protected areas, breeding, habitat restoration.
Food chain — top level?
Tertiary or apex predators.
Abiotic factors — influence?
Determine organism distribution.
Biotic factors — influence?
Affect population sizes.
Organism adaptations — example?
Camouflage for avoiding predators.
Material cycles — example?
Carbon cycle: photosynthesis and respiration.
