Final answer:
Terrapins are threatened by pollution, habitat loss, climate change, predators, and overexploitation. These factors lead to habitat degradation and alter ecosystems, impacting terrapin survival. All options are correct.
Step-by-step explanation:
Some significant threats to terrapins include pollution, habitat loss, climate change, and predators. Overexploitation, such as excessive hunting or collection for the pet trade, also plays a role in the decline of terrapin populations. These threats impact terrapins' survival by directly affecting their immediate environments or altering the broader ecosystems in which they live.
Pollution and habitat loss are particularly damaging, as they can lead to degradation of the quality and availability of terrapin habitats. Climate change introduces a range of challenges, including temperature fluctuations that can affect terrapin breeding cycles and the availability of food sources. Predators, often exacerbated by ecosystem imbalances caused by the aforementioned threats, can also contribute to declining terrapin numbers.
Hence, all of the given options are correct.
