you know tadpoles undergo metamorphosis to become adult frogs, and you suspect the mortality rate is high for tadpoles during this transition. How would you determine the number of tadpoles that survived to become adults

by counting the number of tadpoles and adult animals 2 weeks post-metamorphosis  

Explanation:

During its growth, the tadpole turns into a frog by a complex biological process known as metamorphosis, producing an adult land animal with 4 legs to move and lungs to breathe. During this process, tadpoles face different threats such as, for example, predators (i.e., turtles, birds, fish), diseases that spread quickly through natural populations, limited food, etc. In natural environments, it is possible to determine the mortality rate during metamorphosis by calculating the number of tadpoles and then by comparing it with the number of adult individuals (i.e., post-metamorphosis). Moreover, it is also possible to determine the causes of death by placing fresh tadpoles in experimental optimal conditions and then by comparing both mortality rates. Another mode to determine the causes of death is the examination of these dead animals by a wildlife pathologist.
