There is good amount of evidence to believe that all the life forms have ego. You can not have a life form without the feeling of ego. This ego gives you desire to preserve your self. This ego gives you desire to reproduce. These both factors forms basis of every life form. There is no evidence to believe that this ego is more or less in any species of animal, plant or microorganism. Probably same is true with the viruses also. There is no evidence to believe that this ego is more or less in any individual life form.

all life-forms are located in the biosphere
The layer containing all forms is biosphere. It is the life of all organisms.
I'm assuming you meant "What scientists study all forms of life?" The answer is biologists (the root word "bio" means "life").
A biologist studies all life forms, including animals, plants, and microorganisms. They focus on understanding the structure, function, behavior, and evolution of living organisms.
All life forms are capable of life functions like digestion,respiration,excretion,reproduction,locomotion (internal/external) as living organism.Non life forms are structural elements,compounds with no functional life .

Tenzil Kem is the alter ego of Matter-Eater Lad. He is able to bite through and consume all forms of matter.
it would break the natural web of life and all human and all other life forms would very soon die off
Life forms are indeed related. The reason is due to all life forms starting out with a single, unicellular common ancestor, with that common creature radiating into multiple forms to take advantage of its environment.
