Is a bird an insect

Answer 1

Yes. It is.

The word "organism" as defined by Webster is:

2 : an individual constituted to carry on the activities of life by means of organs separate in function but mutually dependent : a living being

Thus, everything from a single celled organism to the largest or highest form of life we know are all called organisms.

The question now is "What constitutes an organ"? Hilarious jokes aside; an organ is something that carries on a function needed so something can live. Thus, rocks, water, air, all are not what we call organisms because they do not have separate organs and also do not have any way to exhibit life.

Some religious beliefs state that rocks, the water we drink, and the air we breath actually do have life in them and that these "lives" are spirits. While it is true that trees sway in the breeze, the air moves, and water flows - these actions in and of themselves do not constitute life in the ordinary meaning of the word - but they do in the spiritual world. They are also considered "alive" because they move and exhibit such movement to us. Rocks also move. They can tumble down inclines, be moved by some outside force, or break into smaller parts but this movement is either very sudden or can take millennium to accomplish. However you wish to think of these inanimate objects though - they do not fall into the category of organisms because they do not have separate, individual organs. So you can consider them to be alive in a spiritual sense - but in the scientific sense - they are not alive and are not organisms like birds are.

Answer 2

while they are both organisms, they are not the same organism.

Answer 3

no, it is a bird!
