Almost no species ever reaches its biotic potential—the population size that the species could produce if all individuals survived and produced offspring.

Anything that prevents the species from reaching its biotic potential is called a

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
