Question

Which level of organization includes all the other levels of organization?

O organ system
O organism
O tissue
O cell

Answer 1

I would say an organism.

Step-by-step explanation:

Techinally, the biosphere is the highest but in this case organisms include cells, which lead up to make organs which makes an organ system which ulitmately are all parts of an organism

Answer 2

Organism.

Step-by-step explanation:

The cell is the smallest form of life. Cells work together to form tissues, tissues work together to form organs, and organs work together to create an organ system, and organ systems work together to create organisms. I believe "organism" includes all of these other levels.
