Fator ecológico

Em ecologia, factores ecológicos são elementos do ambiente que influenciam organismos vivos.[1][2] Os factores ecológicos podem afectar as espécies: de forma contínua, entre níveis extremos (por exemplo, temperatura e pH); só afectando o desempenho quando atingem valores elevados (por exemplo, toxinas e poluentes); ou o factor é essencial em pequenas quantidades, mas tem influência negativa em valores elevados (por exemplo, NaCl nos animais e micronutrientes como Zinco e Magnésio nas plantas).

Factores ecológicos:

Bióticos físicos e químicos: relacionados aos seres vivos

Abióticos: relacionados com as condições do meio ambiente e competição.

Condições ambientais: são características físicas, químicas e bióticas. Exemplos: humidade, temperatura, pressão osmótica e pH.

RECURSOS: •Energia •Água •Dióxido de carbono •Nutrientes •Espaço > Organismo (indivíduo) gasta para manutenção > desempenho biológico.

Jewish life nevertheless continued after the war, and there is still a Jewish community present, aligned to the NIK. Early Jewish settlement The first Jews in Gron...
