Frog populations are groups of frogs that live in specific habitats, such as wetlands, forests, and grasslands. These populations can vary in size and health due to factors like climate change, habitat destruction, and pollution. Frogs play a crucial role in ecosystems as both predators and prey, helping to maintain the balance of their environments. Monitoring frog populations is important for understanding biodiversity and ecosystem health. Scientists often study frog species to assess their numbers and distribution. Declines in frog populations can indicate environmental issues, making them valuable indicators of ecological changes.
