So basically I'm doing an assignment and I really need help with multiple questions. Here's No. 1 Why would it be important to understand what controls the numbers and types of species in an ecosystem?

It would be crucial to know what controls the numbers and types of species in an ecosystem so that the certain species doesn't overpopulate or go extinct.  Extinction of that certain species could result in a lot of other animals dying or going extinct because that species was their prey.  Another downside of their extinction is that their prey (the certain animal that went extinct's prey) would overpopulate because they no longer have predators which subdue them.  

da.mn that took like long (2 mins xD)

Explanation:

Was that confusing xD i can tell it to u simpler if ya want'

So what's #2?  I'll answer it bc i really need points.  Can u make question #2 10 or 20 points?

even tho idc about points xD

I just need them so i can ask a question

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
