Hello! The answer is D
Primary succession is an event that occurs when an ecosystem is devoid of all organisms and a slow growth of the ecosystem is observed until it reaches a climax population. The most common example of a primary succession is the land development after a volcano eruption.
In graph D a slow increase in the number of individuals is observed until the graph reaches a maximum, that is called the climax population. This is why this graph shows an ecosystem that has undergone a primary succession during the observation period.
From the markings that you had written and erased on your graph, it seems that you already have an idea of what you're supposed to do. Is it that you're having trouble scaling your graph on the provided sheet given the particular data? Or do you have a conceptual question with respect to the instructions?
I've provided the image of the graph according to my understanding of the instructions as stated in 1 and 2, and I've also attached the corresponding Excel spreadsheet that I used to create the graph. While the blank grid that you've attached doesn't scale identically to my graph, it should be possible to transpose the necessary elements into your grid to an acceptable approximation.
That said, please feel free to let me know if you have any clarifications, comments, or questions.
