A limiting factor is a factor in a habitat that limits the growth of a specific population. In the case of these yeast cells, the limited space for growth could possibly be limiting the population; conversely, the limited quantity of food could also be limiting the population of the specie; and finally the source of waste of the yeast which is toxic (as all living things have waste) which might be damaging their environment. Because the yeast cells are not motile, it is very possible that they are crowding specific places too much for them to continue to grow (also because they reproduce as buds from the other living yeast cells). On the extrapolated part of my graph, the population continues to grow at a very low rate, and then the growth stuns, and begins to decline. What happened in the extrapolated part of...
