In older rock layers we find fossils of living things that no longer exist on earth.

Explanation:

Scientists often refer back to fossils found within sedimentary rocks to back their idea that life forms have changed over time.

Fossils are the preserved remains of organisms that once lived on earth. Special conditions must be in play before an organism can become a fossil like presence of hard parts.

  • Fossils are indicators of ancient life forms that has once lived.
  • They provide us with important clues to the nature of organisms that existed in time past.

Afina-wow [57]

The complete question is:

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?

  • Producers
  • Carnivore
  • Herbivores
  • Top predators

Answer: Top predators

Explanation:

The top predators get the least energy because according to the 10 per cent law the energy transfer only 10 energy is transferred to the next successive level.

The next level of the organism receives only 10 of the total energy that the previous level has.

Hence, the top predators have the least amount of energy in it as the energy is transferred through various levels before reaching top predators.
