Overshoot can lead to which ecological consequence among long-term effects?

• A. Short-term resource abundance and increased population size.
• B. Immediate speciation events.
• C. Loss of biodiversity due to resource depletion and habitat damage.
• D. Universal improvement in ecosystem services.

Answer: (C)

Overshoot occurs when a population temporarily exceeds the environment’s carrying capacity, pulling resources down faster than the system can replace them. When this happens, resources become scarce and habitats can be damaged, setting the stage for a population crash and shifts in how the ecosystem functions. Over the long term, these changes tend to reduce the variety of species and disrupt the relationships among them, leading to a loss of biodiversity due to resource depletion and habitat damage. That’s why this outcome best captures the enduring consequence: biodiversity declines as resources are drained and habitats are altered. The other possibilities don’t fit because overshoot is followed by depletion rather than sustained abundance, speciation is not an immediate result of overshoot, and ecosystem services are not universally improved when overshoot occurs.
