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

Answer;
-Down the concentration gradients; evenly distributed
Diffusing molecules move down the concentration gradients until they are evenly distributed.
Explanation;
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.
-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.
Primary succession starts with bare rock which is broken down by either lichen or moss to make soil while secondary succession starts with developed soil
