The body can decide the nutrients it needs
Prolonged exposure to above-normal oxygen partial pressures, or shorter exposures to very high partial pressures, can cause oxidative damage to cell membranes, collapse of the alveoli in the lungs, retinal detachment, and seizures.
Yes, Organisms compete for the resources they need to survive like food, air, water, space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).
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.
I think it is the second one I'm in bio right now and we just finished the energetics unit.
