I hope this answer helps.
Scientists have recently discovered a community of bacteria and clams living under an ice shelf in Antarctica. These organisms live under 600 feet of ice, in the absence of sunlight, and in temperatures considered too cold for most living organisms. The location where these organisms live is unusual because <span> bacteria and clams are found in the same area</span>
Because of human intervention, the former tend to be simpler and more predictable, because fewer organisms--crops or animals--are involved and everything is monitored/
