Which of the following is a limiting factor in lotic ecosystems?
a.

ph

b.

salinity

c.

light intensity

d.

all of the above

Factors that margins production are considered limiting factors. Temperature, nutrients, pH, salinity. and light are the most considered limiting factors in an ecosystem. Among the aforementioned factors, there are only three that are considered as universal limiting factors. These are: temperature; pH; and, salinity. These 3 factors affect the growth of organisms in the ecosystem, as well as their growth development. According to some research, temperature affects the physiochemical limit of an organism. Salinity on the other hand affects the organisms' mobility, (organisms vary salt tolerance) or suspends cell division. The pH of water also affects the organisms' physiological performance, specifically the aquatic organisms. The answer to this question then is letter D," all of the above".
