if there is no plants humans cant get oxygen so naturally people cant exist on earth
Make their own food.
they lay eggs in plants. they can lay up to 400 at a time.
Not on humans or other mammals. Maybe on salamanders and newts they do . . .
Newts can live in dirty water for short periods of time. When keeping a pet newt, you should change the water daily if at all possible.
No. Salamanders (and their relatives the newts) are amphibians which are vertebrates. This means that they have a n internal skeleton like humans do. Some people believe that salamanders and newts have an exoskeleton but this is usually because people find shed skin in the water because salamanders and newts shed their skin like snakes do.
Newts are Ectothermic
Yes, newts have toxins in their skin ranging from being an irritant to deadly to humans. Taricha torosa (California Newt) and Taricha granulosa (Rough Skinned Newt) are very toxic. Ingesting any of the toxins will kill a healthy adult.
newts are ectothermic
all newts are carnivores
Almost all plants benefit humans
Newts live in water but they need to go on to land [[fill a tank up half way or to the platform you Desire for the newt to get air and climb up on]] newts also like plants they prefer real over fake and the only fish you can put in with them in a spacocamis [[suckerfish]] to clean the tank i hope this helped you!
