Habitat destruction is the leading cause for declining populations of species on our planet. due to human development, industry, and forestry, humans are destroying the habitat of many species at an alarming rate. consider the bald eagle. the bald eagle population was threatened in the late 60s and early 70s. to an aggressive bald eagle protection program, bald eagle numbers in the wild have soared as seen in the population graph above. the bald eagle's population very nearly reached extinction. why did the bald eagle's declining population make it more vulnerable to extinction?

Answer: Due to loss of genetic diversity.

Explanation:

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.    

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
