Hummingbirds
They are birds who have a beautiful form to mate each other and they are ones of the little birds in the world, they have an extraordinary way to fly, they are like little helicopters in the sky. They need a lot of food to fly, but if we the habitats they can despair of the world and the animal who eat them, they can despair and like a life cycle.

reproduction
The males try to attract the females by flying through the air and then dives down at top speed. If the female is attracted, they mate. Once the mating is over, the female locates a place for her nest and then she starts to build it. After the nest is built, the female will put her first two eggs. Next, the female will put on the eggs for 14-16 days until they open.














Coral polyps
They life in the ocean and they have two ways to reproduce asexually and sexually. They are home for many fishes and little animals they need the ocean to survive but if we contaminate the water we can make other species die and we can die  because of us.


                                                        
reproduction
The coral polyps can reproduce asexually and sexually. Reproduce asexually by thronging out    (eggs and sperm) to the water and the fertilization is external.and the other is that the eggs stay there and the sperm goes to fertilized de eggs.
