Climate is an abiotic factor - think about how many individual abiotic factors make up something as large as a climate. Natural disasters, such as earthquakes, volcanoes, and forest fires, are also abiotic factors. These types of abiotic factors certainly have drastic effects on the ecosystems they encounter.
Abiotic (Non-Living) Factors Although, not often included in the food web, abiotic factors or the non-living aspects (water, sunlight, temperature, etc.) play an important role. Climate will decide which food resources, and how much water and sunlight are available to organisms in any given ecosystem.escribe zooplankton, phytoplankton, producers, consumers (primary, secondary, tertiary), ecosystem, herbivores, carnivores, omnivores, and decomposers. Ask and discuss what & how human impacts affect the food chain/web and ecosystems.
