Mealworm investigation

Tenebrio molitor is the latin name for yellow mealworms, our test subject for this week.  We all agreed to create a maze at home to better understand where this animal goes.
It uses chemical energy DIRECTLY for food--it acts as a decomposer by eating dead things and it acts as a consumer of plant matter so we might call it omnivorous.
This organism is composed of animal cells that have a nucleus.

Hey how are you guys storing your meelworms? I've been reading websites but they have the confusing tendensy to be contradictory. Saddly, I only took one meelworm home. I realized after plargroup that he would be lonely, and I was right. I don't think he has the will to do exparaments. He just kind of rolls over.

Hi Maggie,
We are storing them in a plastic salad container, filled with oats, and bran. every day we take them out and put them on the counter. Then we turn the heater on, cause my room is pretty cold.

The smaller ones will begin to change into other things if you don't put them into the refrigerator.

That sounds ominous, doesn't it?

Make sure to provide them with a slice of potato or apple as water--all living things we know of need water, right?

No liquid water, unless you really want to test their will to live...
