Answer:
Population dynamics can be described as the size of a particular population and the environmental and biological factors which influence it.
For human populations, a population which is greater than the resources can be controlled by decreasing the number of births in that population. It can be controlled by people migrating from the place due to less resources available.
For animals, the population can be controlled by increasing the amount of predators for the particular population so that they decline in number. Or shifting of the organisms can be done to places where there are enough resources available.
Answer:
Parasitism
Explanation:
Batrachochytrium dendrobatidis is a parasitic chytrid fungus which is responsible for the declining population of amphibians in the rain forests of Panama and Australia.
The fungus grows on the keratinized layer of epidermis on amphibian skin and makes a thick covering of fungus on the amphibian's skin. So as amphibian's skin helps them to maintain the proper osmotic balance in the body so when a thick fungus grows on their skin they are not able to maintain the correct osmotic balance in their body which leads to amphibian death.
So as Batrachochytrium dendrobatidis is a parasitic fungus and gets its nutrition from the frog body and do not kill frog immediately as in predation therefore this relationship can be considered as parasitism.
