possible points: 2.22

if life began in extreme environments like hydrothermal vents, what might this suggest about the possibility of life elsewhere in the universe?

life could not exist without carbon dioxide and chlorophyll

life may develop anywhere energy and basic chemistry exist

life can arise only in oxygen - rich atmospheres

life requires sunlight and earth - like conditions

Explanation:

Hydrothermal vents are extreme environments with no sunlight, oxygen - rich atmosphere, or Earth - like conditions. They do have energy (from geothermal sources) and basic chemistry (various chemical reactions occur). If life began here, it implies that the presence of energy and basic chemistry is more crucial for life's development than specific factors like carbon dioxide, chlorophyll (which are related to photosynthesis in plants), oxygen - rich atmospheres (since vents have different gas compositions), or sunlight and Earth - like conditions.

Answer:

Life may develop anywhere energy and basic chemistry exist
