How might an ecologist test whether a species is occupying its realized or its fundamental niche?

Fundamental niche is the maximum theoretical inhabited hypervolume which a species can occupy in the absence of interactions with other species on the other hand the portion of fundamental niche that a species actually exploits as a result of interactions with other species is called as realized niche.

Explanation:

In, fundamental niche the full range of environmental variables and resources that a species can possibly tolerate and use in the absence of competitors and predators, i.e free from any sort of interference from other species.Thus, fundamental niche is hypothetical.

Where as,realized niche is the actual smaller hypervolume which a species occupies under interference and predation from the other species.Because of interspecific interactions,the realized niche of a species is often smaller then fundamental niche.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.

explanation:

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
