Survival in Animal Habitats

In a forest habitat, some animals have thick fur to keep warm, while others do not. Construct an argument with evidence about why some animals survive well in this habitat and others do not.

• Animals with thick fur can stay warm and survive better in cold conditions.

• Animals with thin fur can stay warm and survive better in cold conditions.

• All animals survive equally well regardless of their fur thickness.

• Animals with no fur survive best in cold conditions.
