yes they have more mass which needs more energy!
On basis of cladistic analysis higher organisms are more closly related to Archaea .
The process of breaking a complex substance down into smaller components is called catabolism. Catabolism is the breaking down in living organisms or more complex substances into smaller ones.
Genitive
smaller organisms are less complex and therefor easier and faster to study and analyze.
An oxygen-based metabolism provides more energy than an anaerobic metabolism, allowing for a larger volume-to-surface ratio of organisms. So organisms could grow larger, allowing their tissues to specialize in various ways, which means increasing complexity.

More complex eukaryotes do not necessarily have more chromosomes than simpler eukaryotes do. An example from the Holt Science book is that fruit flies have 8 chromosomes, potatoes have 48, and humans have 46. The human cells are more complex, but they don't have quite as many chromosomes as potatoes!
Chromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.
After reading your question I am almost certain that you answer how simple life forms become more complex over time. There is but one way for you to go and it isn't down the evolutionary tree!
organisms
no, it was simpler
The breakdown (usually in living systems) from complex substances to simpler substances is called catalysis. In terms of thermodynamics, the breakdown from more ordered (often more complex) states to more disordered (often simpler) states is called entropy.
Yes
human considered complex organism because there are more than 200 organisms in our body
