A researcher in a lab finds a microscopic organism that is a producer. Populations of this organism are found in extreme environments (e. g., hot springs). The researcher will correctly identify this organism as belonging to the domain .

Archaea

Explanation:

Archaea is domain of living organism consisting of unicellular, prokaryotic organisms that are able to exist in extremely harsh environment such as hydro-thermal vents, hotsprings and acidic environment.

Some archaea are known to posses the capacity to carry out a form of photosynthesis using rhodopsin-like ion pumps to move ions against the gradient and produce ATP via chemiosmosis. However, no known archea has the ability to carry out classical photosynthesis like that of green plants.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

this is because the evolution of one species is independent of the other species.
