I'd say it is phosphorus or phosphate. The easiest way to identify the answer is trough these frases:

Plants absorb this nutrient from the soil and turn it into organic compounds through assimilation.

Plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant.

During assimilation, plants provide phofphorous (and other nutrients) to the cells and tissues - plants absorb this nutrient from the soil and turn it into organic compounds through assimilation.

Plants also used phosphorus in processes such as transpiration and photosynthesis wich contributes to the fact that plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant.

Hope it helped,

Happy homework/ study/ exam!

Which is an abiotic factor that can be found in a rain forest ecosystem?
ss7ja [257]

Answer:

A. Air

Explanation:

Abiotic factors are things that are not living.

Air can be found in a rain forest ecosystem, as it can be found in all ecosystems, but it is not living.

On the other hand, algae, flowers, and animals are biotic instead of abiotic because they are living things.

So, A is the correct answer.
