Question

Which scenario describes a way that an abiotic factor can impact a marine system? Liquid water turning into solid ice encourages animal hibernations. Predation on krill is higher at the surface than at the depths. Rapid increases in water temperature cause extensive fish kills. Reproductive rates of seals show a dramatic increase.

Answer 1

Rapid increases in water temperature cause extensive fish kills

Step-by-step explanation:

Biotic factors are all living organisms that contribute to an ecosystem. On the other hand, abiotic factors are non-living factors, such as climatic factors (temperature, rainfall, wind), edaphic factors (soil type, soil texture, soil aeration etc). Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.

Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.
