Answer:

Archaea

Explanation:

Three main domains exist according to classification, two of these domains are characterized to contain organisms that do not have a membrane bound nucleus, in other words, their single circular genetic material (DNA) is not housed by a nucleus. Instead, the naked DNA is found localized to a central region in the cytoplasm called NUCLEOID. These domains are bacteria and archaea domains and they are termed to be PROKARYOTIC.

These domains also lack membrane bound organnelles i.e their few present organnelles are not bounded by lipid layer. Archaea and Bacteria both have cell walls but what makes up the cell wall is different in both organisms. The organism will most likely be an archaea because it portrays its characteristics being that, an archaea is a unicellular prokaryotic organism with a cell wall. It also has the ability to thrive in extremely harsh conditions like the hot thermal vent described in the question.

What that determines if a cell is eukaryotic. *
Dmitry_Shevchenko [17]
To determine whether a cell is a eukaryotic or
prokaryotic cell, one can observe certain features.
If the cell in the question possesses a well-defined
or definite nucleus and have membrane-bound
organelles such as mitochondria, chloroplasts,
Golgi apparatus, endoplasmic reticulum, the cell is
eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell
organelles, the cell is prokaryotic. If ribosomes in
a cell are the 80S (S=Svedberg units) type, the cell
is eukaryotic and if ribosomes are 70S type then it
is prokaryotic.

Contemporary landscapes result from many causes, including variability in abiotic conditions, such as climate, topography, and soils; biotic interactions, such as competition, mutualism, herbivory, and predation, that can generate spatial pattern even when environmental conditions are homogenous; natural disturbances. I hope this helps :)

Explain how the edges and corridors can strongly influence landscape biodiversity
Dahasolnce [82]

Answer:

The edges or boundaries between the ecosystems and within it are the illustrating characteristics of landscapes. In a landscape, the biodiversity is affected by the composition of the landscape itself. When an area possesses boundaries or edges, which minimize the area of the habitat, it also starts to minimize the number of species, which can associate with the communities.  

The multiplication of edge species can exhibit both negative and positive influences on the biodiversity of a community. On the other hand, corridors refer to the region associated with the populations of wildlife distinguished by human activities like road construction. The prime objective of designing habitat corridors is to enhance biodiversity. The corridors that have been protracted to other habitat patches can reinstate a certain degree of space and at the same time reestablish certain chances for genetic diversity.

Why can’t food chains go on forever?
bearhunter [10]

Answer:

Because at some point in that food chain, the energy consumption has it's limit, and the predator will not have anything to hunt it. There is a limited amount of energy in a food chain that can go around, and once you reach the predator, that energy doesn't quite run out but it hits that limit where the chain has to repeat itself.
