Answer:
population expansion decreases as resources become scarce, leveling off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.
Explanation:
This process requires large volumes of water to pass through absorption surfaces to get enough oxygen into their bodies using their mouths and gills. These body parts work like a pump to keep water moving over the gas absorption surfaces of the gills.
If you talk about the process of fission in the nuclear field then the most used is U-235 because is the easiest to use. Have in mind that the majority of uses of uranium is U-238 but the easiest to be used is U-235
The carnivore population would also increase because there would be a
larger food-source for carnivorous so more of them would be able to
survive.
The carnivore population would go up as well because they have more food
(herbivores) to eat. There would be more food to sustain the carnivore
population.
