4. One advantage of biodiversity in an ecosystem is
1) guarantees that the largest organisms will dominate the area
2) ensures a large amount of identical genetic material
3) develops relationships between organisms that are always positive
over long periods of time
4) increases the chance that some organisms will survive a major
change in the environment
