Answer 5

I'm not sure but I think your answer in question 1 is wrong ,since there are also 1 cell organisms,like some bacteria,so it's not nesessary to be composed by cellS in order to be alive.

Answer 6

okay, with the characters of living things, you don't need atoms, you need cell, homeostatic and metabolism. for #2, I think you need to have DNA, cuz light and able to move is nothing, plants can move too. Energy is kinda silly, you need to obtain and use it, not produce it lol

Answer 7

#3 i dunno what it that mean, #4 i think is either c or d. #5, is tissue, is like your muscle

Answer 8

It isn't tissue. The hierarchy goes:
Atom, Molecule, Organelle, Cell, Tissue, ORGAN, Organ System, Organism, POPULATION, Community, Ecosystem, Biosphere
This is from least complex to most complex.
