To answer this question as it is written: not necessarily. An organism (bacterium) can be smaller than tissue (the cartilage in my ears). By definition, an organism is more COMPLEX than a tissue, but not necessarily bigger.
yes because a tissue makes an organ
Not necessarily. Organs are not always bigger than tissues, they are just more complex. An organ can be as small as a lymph node, but a tissue may be as big as a muscle. So, the more complex it is, being made of more than one type of tissue classifies it as an organ, whereas the similarity of all the cells being the same categorizes it as a tissue. Organs are things like hearts, lung, livers, etc. Tissues are small/tiny pieces of animal or plants containing similar cells.
A universe is bigger than an organism.
an eagle, hawk, animals bigger than it that is a predator.
A tissue because cells form together to make tissues.
A tissue is NOT more complex than a organ because a tissue is 1 level below organs. I know my answer is not clear but I have a hard time when it comes to science.
Yes ecosystems are the environments the organisms live in.
tissue culture
Muscle tissue forms an organ, which many different organs create an organism.
If the organism is a multicellular eukaryote comprised of more than one cellular tissue than this would be expected.
When an organism is petrified its organic tissue is most likely replaced with minerals.
Muscle tissue forms an organ, which many different organs create an organism.
organ is bigger
