Without the mountain lions, increased numbers of deer may reduce the food supply available to other herbivores, such as field mice and crickets. as a result, populations of deer, mice, and crickets might decline, causing a population decrease in species that feed on these organisms as well. this example implies that properly functioning predator/prey relationships do which of the following?
select all that apply.

a: harm all of the organisms in an ecosystem b: throw an ecosystem out of balance
c: result in food surplus for the entire ecosystem d: maintain balance within an

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
