This aquarium exhibits biotic and abiotic factors in an aquatic environment. one of the abiotic factors is

a) coral.

b) fish.

c) plants.

d) water.

The answer is water because water is not living and abiotic means not living.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

a compound light microscope is used to magnify objects in steps.  

hope it
