Question

There are some ecosystems that can survive without sunlight as an initial energy source. Instead of photosynthesis, the autotrophs in these systems use a process called__ in which they harness chemical energy released from sulfur vents under the ocean, rather than from the sun.​

Answer 1

Instead of photosynthesis, some of the autotrophs can survive without sunlight as an initial energy source because they use a process called chemosynthesis in which they harness chemical energy released from sulfur vents under the ocean, rather than from the sun.​

What is an Ecosystem?

An ecosystem may be defined as the place or area where members of different species live together and interact with one another for the purpose of food, shelter, and space.

The process of chemosynthesis does not utilize energy from the sun to synthesize food. Rather, it makes food utilizing energy from chemical reactions, frequently incorporating hydrogen sulfide or methane with oxygen. The autotrophs who perform this process are known as chemoautotrophs.

Therefore, it is well described above.
