The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
What determines the chemical properties is : color, hardness, luster, crystal forms, density, and cleavage.
The final stage of the mitotic phase is cytokinesis, during which the cytoplasmic components of the daughter cells are separated either by an actin ring (animal cells) or by cell plate formation (plant cells).
