Photosynthesis gives the plant food/nutrients to be able to survive. They make their own food
        
             
        
        
        
Explanation: Sudden Increase Factors:
- Since there are no predators, there are no ways they could be eaten, with this case, it significantly increases the population.
- Since there are a lot of females, and some males, the males could find mates, and have some baby reindeer, which also increase the population.
Sudden Decrease Factors:
- One decreasing factor is starvation. With there being so many reindeers, all the food is going away quickly. After a few years after the growth spurt, most of them probably died because of there not being a lot of food.
- Another decreasing factor is Old Age. Since there are 21 females, they are older than the babies, and they couldn't have lived much longer, and probably died.
- Another factor; sickness. With there being starvation, their immune system is degrading, and meaning sicknesses could come, so maybe a huge sickness // disease came, and wiped out quite a bit of the population.

Answer:
flooding
Explanation:
The hurricane brings in enormous amounts of rainfall with it, often resulting in flooding. The ground squirrels in this scenario live relatively close to the ocean shore. They live in burrows, spending big portion of their time in them, as well as having their young ones sheltered in them. The heavy rainfall and the flooding of the area will result in filling the burrows with water. The damage for the population of ground squirrels will be enormous, with their young ones all drowning for sure, and the majority of the adults getting drowned as well, or maybe even all of them. Hope this helps!!!!!
