Dr. digger, a paleontologist, finds a fossil that he describes in his journal.

the creature was approximately 1 meter long, with its backbone fused into a large shell covering the body cavity. it had a beaklike mouth, without teeth, and all four limbs were in the form of flippers.

based on anatomical similarities, to which modern animal is dr. digger’s creature most closely related?

zebra
bony fish
sea turtle
snake

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.    

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
