this week in science #13



    
If we were to leave the spider habitat tanks sealed but removed all of the plants then their would be no oxygen inside of the tank. The plants give oxygen to the spider, Nothing would grow in the tank because there would be no sun or water for anything to grow. The spider needs plants for oxygen to live inside of the tank, the plants gives the spider energy and  food in order for it to live.
