* Vast Diversity: There are thousands of frog species worldwide, each with its own lifespan, mortality rate, and population size.
* Natural Predators: Frogs are a vital part of the food chain, and many animals prey on them.
* Habitat Loss and Degradation: Pollution, deforestation, and climate change are major threats to frog populations.
* Disease: Amphibian diseases like chytridiomycosis can cause mass die-offs.
* Data Collection: Tracking frog populations and mortality rates across vast areas is incredibly difficult.
Instead of focusing on a single number, it's more important to understand the factors that contribute to frog mortality and work towards conservation efforts to protect these amazing creatures.
