Final answer:
The deciduous forest has a moderate climate, with trees losing leaves in fall and winter, and animals adapted to the seasonal changes, hence the correct answer is C) Deciduous forest.
Step-by-step explanation:
The biome characterized by moderate climate zones, trees that lose their leaves in fall and winter, and animals that adapt to cold winters and mild summers is the deciduous forest. In these forests, deciduous trees are the dominant plant life. These trees are notable for shedding their leaves each fall and remaining leafless through the winter, resuming photosynthesis and leaf growth with the rise in temperature during spring. The temperate forests experience moderate rainfall and temperatures conducive to seasons, which defines their distinct ecological cycle. Animals in this biome are adapted to the changing seasons, with some migrating or hibernating to cope with the winter cold. Consequently, the correct answer to the question is C) Deciduous forest.
