If I'm not mistaken, it leaves through the osculum which is a cavity located on the upper part of a sponge.
Sponges feed through a process called filtration, which means that they filter the water in search of nutrients. And after they collect everything they need from the water, they need to let it out somehow; through the osculum.
Hope it helped,

Carbon Monoxide has 2 atoms total - one atom of carbon (C) and one atom of oxygen (O) chemical formula is CO
Ethylene has 6 atoms total, 2 atoms of carbon (C) and 4 atoms of hydrogen (H), chemical formula is C2H4.
Ethylene has four more atoms than carbon monoxide (6-2) = 4
Male animal aggression during mating season. The evolutionary purpose of most species is to repopulate and keep the species alive long enough to become the highest being it can evolve into (We humans have done the best at this so far). So, every male in a species gets aggressive during mating season because the stronger ones are most likely to have healthy offspring. So, when animals fight they are fighting to keep their species alive. If you think about it who wouldn't want to be responsible for the evolutionary breakthrough that kept a species alive over thousands of years? hope this helped.
