Is decay of dead plant material a biotic factor or an abiotic factor?
Juliette [100K]
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!

What will happen to a population of predators if there is a sudden, temporary increase in the number of prey?
alekssr [168]
The number of predators and preys change from time to time following cycles. Whenever there is fewer prey, predators start dying because they have not enough to eat; however, that provokes the population of prey to be increased while there are fewer predators. So if suddenly the number of prey gets bigger, regardless of the number of predators, the cycles get disturbed by this sudden occurrence. The predators will get more to hunt, therefore getting more violent.
