Which statement represents an abiotic environmental factor in an ecosystem?
sukhopar [10]

Answer:

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, <u>air and temperature</u>.

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