parasite children

in biology today, we talked about symbiosis - two animals gaining things from each other (or not). There are three distinct types of symbiosis:

1. mutualism: both people benefit

2. commensalism: one benefits, the other is unaffected

3. parasitism: one benefits, the other is harmed

she said that scientifically speaking every human was once a parasite. when people were little emryos in there mother's stomach they were making their mother sick and making her hurt and tired while gaining nutrients. they also made the mother's very very fat. this is exactly what parasitism is!!! so tell your parents that they all had a parasite in them however many years ago, and see what they say.

P.S. some would argue that children are still parasites. using up the families money and food, etc.
