Flashcards: Ecosystem Interdependence and Conservation — 20 cartões

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.
