Sadly,I only know the answer to # 1.U,Me,and ur friends (or the animals trying to keep their family safe) and we/they are protecting the forest,we can't breath with out trees after all!
To scientifically answer the question using scientific reasoning, explaining generally why it makes sense that the lion population is taking longer to recover than the herbivore populations is that;
The herbivore populations have enough food in the ecosystem,this food is in the form of flora,and this food they get keep their energy flowing and also has a way of ensuring their high recovery rates.
Then looking at the lion population,on the contrary,they have to depend on feeding on smaller animals this is because the larger animals reproduce at a smaller pace, and lions with a smaller prey,lions don't get enough and adequate food/nutrition for themselves and also for their pride of lions,this ascertains the fact that lion population take a longer time to recover than it's counterparts which is the herbivores.
It reproduces cells to work for all systems
