Determine what particles will pass through passive transport

1. Simple Diffusion is a passive transport in which particles pass through the plasma membrane surrounding a cell. Diffusion is the random movement of particles with the net direction of the particles being from an area of higher concentration to an area of lower concentration.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
