According to the cell theory, which describes cells?
all organisms are composed of multiple cells.
all cells have the same structure and function.
cells are found in everything on earth.
living organisms are not created spontaneously.

Cell theory states that:

1. All living organisms are made up of one or more type of cells.

2. Cells are the basic structural and organizational unit of all organisms.

3. All cells come or arise from the pre-existing cells.

Hence, the correct answer is Living organisms are not created spontaneously i.e. they arise from pre-existing cells.

Other options can be excluded as: organisms can be unicellular also, cells have different structure and function (such as muscle cell, nerve cell etc). Lastly, cells are found in living organisms only.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
