Love and Unity :) just kiddddding aging cells stop dividing because they become senescent. They do this by sending chemical signals to each other so that they know
Answer:
ATP gives free energy that the cell can use for energy using processes in the cell
Explanation:
sometimes ATP is necessary for the transportation of nutrients in the human body. ATP gives the cells energy to do for example endocytosis or exocytosis. (actively absorbing nutrients or emitting nutrients)
Decomposers also break down the bodies of dead organisms resulting in nitrogen being returned to the soil as ammonia. In some conditions denitrifying bacteria in the soil break down nitrates and return nitrogen to the air.
