Answer:

The Archean Eon marked a time when Earth’s climate began to stabilize.

Earth cooled down from its molten state. It eventually could support oceans. Tectonic activity built continents.

In the Archean Eon, oxygen filled the atmosphere and most of the world’s iron ore was deposited.

Because the Earth’s conditions stabilized, eukaryotic and multicellular life could finally emerge in the Proterozoic Eon.

Which of the following correctly shows how energy flows in an ecosystem? *
Nataliya [291]

Answer:

The correct answer is - sun - producer - the consumer – decomposer.

Explanation:

Sun is the ultimate source of the energy on the earth and is responsible for all the energy that is present or moves between various organisms in an ecosystem.

Sun provides energy in the form of light energy which is converted by the producers by photosynthesis into food and when consumers eat producers for food and energy 10 percent of energy passes from the producers to the consumers and the rest 90% lost during life processes. At the end of the chain, decomposers get energy from the dead matter of the consumers.
