Question

6. Select the correct terms to complete the statement about early life on Earth.

When life first evolved on Earth, there was virtually no oxygen in the atmosphere. The earliest prokaryotes were likely anaerobic | aerobic meaning they did not require oxygen
to produce energy. Over time, photosynthetic
| chemosynthetic prokaryotes evolved, which made energy from the sun. The chemical reactions involved in this process released carbon dioxide
| oxygen | nitrogen into the atmosphere. This allowed for the evolution of eukaryotes.

Answer 1

Step-by-step explanation:

When life first evolved on Earth, there was virtually no oxygen in the atmosphere. The earliest prokaryotes were likely anaerobic meaning they did not require oxygen to produce energy. Over time, photosynthetic prokaryotes evolved, which made energy from the sun. The chemical reactions involved in this process released oxygen into the atmosphere. This allowed for the evolution of eukaryotes.
