Question

Students created a computer model of an ecosystem process to predict the density of different tree species in an area over 100 years. The graph shows the outcomes of the model for one of the tree species.



In the years 75 to 100, the population can best be described as reaching

Question 30 options:

Extinction


Evolution


Exponential growth


Carrying capacity

Answer 1

In the context of an ecosystem model predicting the density of tree species over time, if the graph shows that the population of the tree species stabilizes and levels off after a certain point (in this case, years 75 to 100), it suggests that the population has reached a balance with the environment. This is typically referred to as the "carrying capacity," which is the maximum number of individuals of a species that an environment can sustain over time.

Given this understanding, the correct answer to the question is:

**Carrying capacity**
