Question

question 4 (multiple choice worth 2 points) (01.01h mc) the yellow perch is a fish species found in lake erie, u.s. it survives in the lakes freshwater with low salinity. this salinity is a biotic factor, the oxygen in the water dissolves most of the salt a biotic factor, the water - to - salt ratio allows for species adaptation an abiotic factor, the salt is reduced as it gets pushed through groundwater sources an abiotic factor, the salt levels contribute to the lakes warmer temperatures

Explanation:

Salinity is a non - living (abiotic) factor in an ecosystem. Biotic factors are living organisms or factors related to living organisms. Abiotic factors are non - living components like temperature, salinity, etc. Groundwater sources can dilute salt in a lake, affecting salinity levels.

Answer:

an abiotic factor, the salt is reduced as it gets pushed through groundwater sources
