ou are studying the population dynamics of an algae species that recently invaded a lake. You measured the amount of algae in the lake the time of the invasion and then for six years afterward (shown in green dots below). You also conducted experiments showing there are enough nutrients entering this lake to support a population density of 200 cells per mm- of algae, marked below as a dashed orange line labeled K. Based on your data, you want to predict how large the algae population will be in the future, assuming no major environmental fluctuations. Here, population density can be modeled in the same manner as population size. 1. what would you assume the algae population density will be 20 additional years in the future, assuming no environmental changes occur? __cells/mm^2

Question

You are studying the population dynamics of an algae species that recently invaded a lake. You measured the amount of algae in the lake the time of the invasion and then for six years afterward (shown in green dots below). You also conducted experiments showing there are enough nutrients entering this lake to support a population density of 200 cells per mm- of algae, marked below as a dashed orange line labeled K.

Based on your data, you want to predict how large the algae population will be in the future, assuming no major environmental fluctuations. Here, population density can be modeled in the same manner as population size.

1. what would you assume the algae population density will be 20 additional years in the future, assuming no environmental changes occur? __cells/mm^2
