Which animals have an amniotic egg

Primates, rodents & rabbits, crocodiles, and birds.

Explanation:

When looking at a cladogram, the red marks will refer to anything above it. Anything below a red mark will not have the featured attribute, but everything after it will have it.

In this case we are looking at having an amniotic egg. As you can see, the red line is in between amphibians and primates. Since cladograms work from left to right, we can say that sharks, ray-finned fish, and amphibians can not produce amniotic eggs, while...

Primes, rodents & rabbits, crocodiles, and birds can produce amniotic eggs.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
