What is the main difference between primary and secondary ecological succession?
Primary begins WITHOUT soil; Secondary begins WITH soil
Primary is the first state and secondary is the second stage

Primary begins WITH soil; Secondary begins WITHOUT soil
What is ecological succession?
A series of predictable changes that occur in a community over time.
It is the number of fish increasing.
It is the seasons of the year.
It is that rain follows cloud formation.

The function of the cell wall is
absorbs energy from sunlight
controls the material passing into and out of it
encloses the cell membrane and gives to the cell plant shape
The image shows a

What is the definition of OSMOSIS?
Diffusion of water through a selectively permeable membrane
Molecular structure that surrounds the cell and controls what enters and leaves the cell
Movement of molecules across the cell membrane against the concentration gradient
Movement of molecules across the cell membrane from an area of high concentration to low concentration
