What is an organism that no longer exists called?
extinct. A species that no longer exists anywhere on Earth.
What is the process by which all the different kinds of living things have changed over long periods of time is called?
Evolution is a change in the characteristics of living things over time. As described by Darwin, evolution occurs by a process called natural selection.
What is a hard and rocklike fossil?
A hard, rocklike fossil, called a petrified fossil. develops when minerals fill spaces left when the original substance dissolves.
In which rock type do you think fossils which are the remains of past living organisms are most often found quizlet?

Who thought organisms could never go extinct?
Jean Baptiste Lamarck (1744-1829) is one of the best-known early evolutionists. Unlike Darwin, Lamarck believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human “perfection.” Species didn’t die out in extinctions, Lamarck claimed.
Can organisms be alive without energy ability?
Living Things Need Resources and Energy Energy is the ability to do work. But you are not the only one who needs energy. In order to grow and reproduce and carry out the other process of life, all living organisms need energy.
Why are fossils rarely found in metamorphic or igneous rocks?
Igneous rocks form from molten rock, and rarely have fossils in them. Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that contain fossils.
Why does a frozen organism not decay?
The low temperatures of frozen soil and ice can protect and preserve organisms. Because most bacteria cannot survive freezing temperatures, organisms that are buried in frozen soil or ice do not decay.
