No, Derpwad
A lion would try to eat a giraffe, but may not succeed.
try giraffe
There are not very many animals that will try to cross a giraffe. Taking them down is quite difficult. The only real enemy of the giraffe is the human.
yes. Their favorite leaves are from thorn acacia trees
Hippos are herbivores,plant eaters, and would not try to eat a giraffe.
Little animals are always great choices. You can try a baby giraffe, elephant or lion. Other choices you have are Disney characters. There are many to choose from in that category.
a coyote
If food is scarce, then yes. While not many other species can eat the leaves of the top of the trees, all giraffes can, and will try to eat those. So if food is scarce they will be competing with each other for food.
Not really. They might try for a nibble if the come across one already dead, but meerkats aren't big scavengers and certainly can't hunt anything as big as a giraffe.
frogs
Very good question, bats,snakes, and frogs, of course many other creatures
They don't try, but in the movie Zookeeper (2011) the Animal-rights defenders protested the makers after the death of a giraffe that appeared on the movie. :-(
