How do seeds travel by Animals?
Seeds stick to fur
Animals carry them to new places
These animals are a type of mammal, and their babies develop in a pouch. (ex. opossums)
Marsupials
What is it called when seeds are spread by wind, water, or animals?

Spores
How do seeds travel by Water?
Seeds float (like coconuts)
These animals have scales, lay eggs, and are cold blooded. (ex. snakes, turtles)
Reptiles
