What is the ploidy of organisms that have two sets of chromosomes?

Explanation:

The ploidy of organisms that have two sets of chromosomes is called Diploid.

Ploidy is defined as the number of chromosomal sets present in an organism. i.e of homologs of chromosomes present in the cell. An organism which has two sets of chromosome is a diploid organism, whereas the organism which has three sets is called triploid, the organism with four sets is called tetraploid.

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.    

b because they naturally adapt to their environment plz mark brainliest
