Nature Zone SNZ54511 Feeder Insects Total Bites Soft Moist Food with Spirulina, 10-Ounce

Can you feed this to mealworms and insects eating plants?

Can i feed these to my chameleon to hydrate and or for snacks?

If you use this, do you still need to put a sponge of water in the cage? Or is that too much water? Trying to figure out why my crickets keep dying

Is there any pieces that are left over after feeding to mealworms?
