Q. Choose the correct statement about large populations of organisms are centered on deep sea hydrothermal vents.

1. The energy captured by these organisms is thermal in natural and allows them to thrive in mixed populations.
2. The species found at each site are usually evenly mixed between producer plants and consumer microorganisms and animals.
3. Fungi and protozoans are usually not represented in these populations.
4. Only a single species is found at any one vent, although the species varies from vent to vent.
5. Energy from mineral ions feed producers, which in turns feed varieties of consumers.
