crawls out on land (E). The frog resorbs the rest of its tail and continues to

grow until it reaches its adult body size (F).
During drought, frogs and toads survive by burrowing into the soil. A

nearby pond has been dried for more than a year, and some frogs are likely

hiding in what was once the pond's bottom.

Those frogs will spend their days hunting insects and their nights'

serenading mates. They have to work fast, for there is no guarantee the pond
will stay wet. If the pond begins to dry, they will retreat into the mud until

the next time the pond receives runoff. Frogs stop mating during droughts.

Other factors that affect the life cycle of frogs are the use of pesticides

and insecticides of humans in their farming. The pesticide is used to kill

pests while insecticide is used to kill insects that infest the plants. When
pesticide and insecticide are used by farmers, the population of frogs and

other aquatic animals were poisoned. Frogs also starved due to the low

population of insects as their food which leads to their death. Another
human activity that affects the life cycle of frogs is the human hunting of

adult frogs to be used as food. Migration or change of place of some

migratory birds from cold countries to warm countries like the Philippines to
hunt for food can also affect the population of frogs in a certain area.
