Scientists assume that an organism’s ancestors required a climate similar to the climate required by the present-day organism. t or f

True

Explanation:

The scientist assume that the climate required by the ancestors of the organism had the same climate as it is required by the organism on the present time.

The climate required by the same type of organism will be same, this was concluded by observing the fossils that was found during the present time.

The fossil record showed that the conditions and climate is matched is same for the organism.

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.
