Answer:
Microbial control agents can be described as agents which will inhibit or prevent the growth of microbes. Hence, they will prevent the damages caused by microbes.
Microbial control agents can either inhibit the growth of microbes. In this way, the population of the microbes will not expand and hence, the effect of the microbe on a host will be controlled.
Other microbial control agents kill the microbes and hence, control the effect of microbes.
*The rate at which radioactive decay occurs.
*How much radioactive decay has occurred.
Photosynthesis makes the glucose that is used in cellular respiration to make Atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while the water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Technically you are able to argue both ends. Biotic factors are living things while abiotic factors are no living things. since the plant was once living, you can argue that it is a biotic factor, however, I would say the dead plant decay would be abiotic because it is not living anymore. I hope that helped!
D. all of the above
this sounds a lot more like geography than biology by the way
