How can the extinction of an organism be inferred from evidence in the fossil record

Through time the different species faces some of the most unusual form of environmental factors, as some of the factors include the lack of a natural resources, lack of shelter and along with that some of climatic changes are also held responsible for the survival of the organisms inside the region under consideration or observation.

What is meant by extinct How do scientists obtain information about extinct species?

How do scientists obtain information about extinct species? A species is extinct if no members of that species are still alive. Most of what scientists know about extinct species is based on the fossil record. What are mass extinctions?

Explanation:

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
