Yes ecosystems are the environments the organisms live in.
A universe is bigger than an organism.
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.
an eagle, hawk, animals bigger than it that is a predator.
No, an organism is not bigger than a community. An organism refers to a single living entity, such as a plant, animal, or microbe, while a community consists of multiple organisms of different species interacting in a specific environment. Therefore, a community encompasses many organisms, making it larger in scale.
organ is bigger
Yes, an ecosystem is typically larger and includes all living organisms in a particular area as well as their physical environment, while a habitat refers to the specific place where a particular organism lives. Habitats are part of ecosystems.
You have the individual, the organism, then many of the same organism population, than you have multiple populations, community, and then you have multiple communities and abiotic factors, ecosystem. If you were to go further you could say multiple ecosystems, biosphere.

Biomes or ecosystems fill this description.
yes
it allows it to grow bigger in size and allows specialization
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.
