What can result from ecosystem disruption?

Ecosystem disruption typically leads to shifts in species composition and abundance. Disruptions can occur due to various factors, such as natural disasters, human activities, pollution, or invasive species. These disturbances can change the availability of resources, alter habitats, and affect the interactions among species. As a consequence, some species may decline, while others may thrive or invade, resulting in a new balance within the ecosystem.

For instance, a fire may clear a forest, allowing certain plant species to flourish while displacing others. This shift can affect the entire food web, from herbivores that rely on specific plants to predators that depend on those herbivores. The overall biodiversity may change as a result, with new species composition emerging in response to the altered conditions of the habitat.

Thus, the correct answer reflects the reality that ecosystem disruptions often lead to dynamic changes in the composition and abundance of species, rather than static or enhanced conditions.
