Which statement represents an abiotic environmental factor in an ecosystem? •The lion hunting the gazelle.
•The flower growing on the vine.
•The fish swimming in the lake.
•The air temperature in the mountains.

An example of an abiotic factor within an ecosystem is the air temperatures in the mountains.

Explanation:

In an ecosystem, abiotic factors refer to all those non-living elements, which depend on chemical and physical elements. Water, soil, wind, temperature, climate, minerals and soil pH are abiotic elements.

In comparison to the other statements, the one that corresponds to an environmental abiotic factor is the air temperature in the mountains, describing even two factors, air and temperature.

    The other alternatives, lion hunting the gazelle, flower growing on the vine or fish swimming in the lake represent biotic or living elements of an ecosystem.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

i am going to guess that it is co2.
