Answer and explanation:
As for <u>oligotrophic lake</u>, the answers would be as follows:
<u>Oxygen level (+).</u> This is because oligotrophic lakes are usually deep waters, and it's on deep waters that oxygen is usually far more contained and dissolved.
<u>Nutrient content (-). </u> Oligotrophic lakes handle a really low level of nutrients. This is the reason why it's inhospitable for any type of fauna and vegetation.
<u>Productivity (-). </u>Following what it's stated above, oligotrophic lakes are essentially unproductive because of its poor nutrient content.
