Given what we know, we can confirm that cells tissues populations and ecosystems are all examples of components of the biosphere. 
<h3>What is the biosphere?</h3>
- This is considered the highest level of organization of life on earth. 
- It is the sum of all of the ecosystems present on the planet. 
- Every living thing, from cells to entire forests, are contents of the biosphere. 
Therefore, given that the biosphere is the sum of all ecosystems on planet Earth and includes every living thing, we can confirm that cells and ecosystems are both prime examples of this.
