An egret eats insects swept up by cattle grazing. This is an example of which of the following:
This question was on our science test today, and frankly, I find it to be ridiculous. Do you know why I find this question ridiculous? Because it implies that we have been taught what the heck an egret is, or that we might know SOMETHING that could POSSIBLY lead us to the correct answer, but in reality, the situation is in fact the complete OPPOSITE. Our science teacher deliberately told us that we DIDN'T have to memorize examples of parasitism, commensalism, and mutualism! In fact, even if I DID decide to memorize examples from our science textbook, just for the heck of it, I WOULD STILL NOT KNOW WHAT THE HECK AN EGRET IS!!!!!! AARRG!!!!!
Sorry. I really needed somewhere to vent, and this seemed more appropriate than actually telling this to my science teacher :)
