Your answer is After DNA replication, the cell leaves S phase and enters G2, when the cell prepares for mitosis or meiosis. At the G2 checkpoint, the cell checks two things. First, it checks DNA for any damage that might have occurred during replication. It also ensures all the proteins needed for cell division are present.
G-2 phase represents the 3rd sub-phase of inter-phase that occurs within the cell cycle. It takes place right after the mitosis cell division process and successful completion of S-phase where DNA replication takes place in the cells.
The cell continuously grows and expands, and thereby produces new types of proteins during the time between synthesis of DNA and mitosis cell division. By the end of this time, there occurs the G-2 checkpoint that checks whether the cell can enter into the Mitosis cell division or not.
Thus, it can be concluded that the cell prepares for the cell division process in the G-2 phase of the cell cycle.
<h3><u>The Food webs are preferred over food chains for representing the flow of energy in an ecosystem for the following reasons:
</u></h3>
The food webs are higher in complexity when compared to food chains and also, in food web, more than one primary producers is present which increases the 'flow of energy' in the ecosystem.
Food web represents the real life better than the food chains do.
Food web shows many different paths through which the organisms can be connected.
