Biome Oxygen level Nutrient Content Productivity
Oligotrophic lake + _ _

Answer 1

Answer and explanation:

As for oligotrophic lake, the answers would be as follows:

Oxygen level (+). This is because oligotrophic lakes are usually deep waters, and it's on deep waters that oxygen is usually far more contained and dissolved.

Nutrient content (-). Oligotrophic lakes handle a really low level of nutrients. This is the reason why it's inhospitable for any type of fauna and vegetation.

Productivity (-). Following what it's stated above, oligotrophic lakes are essentially unproductive because of its poor nutrient content.
