i chose gets rid of waste my answer is as follows

Bacteria would get rid of waste by passing it through its cell membrane. It passes through it as a liquid.
A grasshopper would get rid of waste by taking a breath and by urinating and by having a bowel movement. Although, grasshopper release urine and stolid waste all at once like birds.
Bears release waste some what like a grasshopper, because they both release waste when they take a breath. However, unlike the grasshopper they do not release solid and liquid all at once. Bears can choose to one or the other.
Fish release waste some what like the bear and the grasshopper, because they both release solid waste through their anus. Fish however release urine every time they breath.
thanks a bunch
