Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.
Explanation:
From Penn
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.
