Answer:
The correct answer to the following question is "Heterogeneity in disturbance regime".
Step-by-step explanation:
- Environmental heterogeneity seems to be a standard occurrence of natural environments and therefore is intended to improve species diversity by enabling separation of niches and coexistence of species.
- When this issue concerns settled and unstable ecosystems, it thus refers to various degrees or levels of disruption throughout the two habitats. The problem is not about variability in environmental influences, as well as food resource quality.
So that the above is the right answer.
