how does amoeba catch its prey?

When there is lots of food nearby the amoeba, it will stop moving, and extend psuedopods, or false feet, all around their body, as a trap for the food. When a creature gets close to the amoeba, the amoeba will form itself around its prey. The amoeba may also extend another psuedopod over its pocket, or food cup, that the food is stored in, so it can't get out. This food cup then moves to the middle of the amoeba, where chemicals flow into the pocket. The useful parts of the food flow into the body. When the only remains of the food is waste, the non-solids move up to the amoeba's membrane, and leaves the creature's body through a small hole. The solids turn into crystals. After the waste liquid exits the hole, then it closes up. If some water gets through the hole, the membrane will drain it out. Amoebae can't get rid of waste. The only way to get rid of it is to divide into two creatures. Each half of the amoeba gets the waste.
