To determine the type of succession taking place based on the information given, we need to clarify what primary and secondary succession entail:
- **Primary succession** occurs in an area where there were previously no organisms and no soil (e.g., after a volcanic eruption or glacial retreat).
- **Secondary succession** occurs in an area that has been disturbed but where soil and organisms still exist (e.g., after a forest fire or human activity).
Without specific information about the initial conditions of the area and the presence of soil, it's challenging to determine definitively. However, the options provided allow us to evaluate the possible types of succession based on the details mentioned.
Given that you mentioned grasses first and that the changes led to trees replacing bushes, it suggests a succession process where an ecosystem gradually develops over time—a characteristic of secondary succession since it implies that some form of vegetation existed prior.
Therefore, the option that best describes the succession taking place is:
**Secondary succession because the first organisms to grow were grasses.**
