Biotic Factors depend/rely on abiotic factors because living things (biotic) need nonliving things (abiotic) to survive. Biotic rely on other Biotic factors because they need the food and resources from other living things.
For example, we (biotic factors) need energy from the sun and oxygen/air ,which is abiotic factors, to live and grow. Just like plants (biotic) need the sun's energy (abiotic) to help it grow.
I hope u understand me. Sorry If u don't

I think theres a few methods to do it, but this is probably the most efficient.
Physician has prescribed 2.5% of 500ml
Actual amount of Aminosyn in this prescription is
500*0.025= 12.5ml of Aminosin
Therefore you need to ensure when you pour your solution of the 8.5% Aminosyn, it has 12.5 ml of Aminosyn.
To work out how much 8.5% Aminosyn you should pour, you must think of the 12.5ml as 8.5%
Therefore 1% = 12.5/8.5= 1.470588
Therefore the amount of 8.5% solution you need to pour is 100* 1.470588= 147.1ml
Then make up the rest(352.9ml) by adding distilled water. You now have 500ml of 2.5% aminosyn.
