INSECTSYadira: Insects they have a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. They are among the most diverse groups of animals on the planet. Insects may be found in nearly all environments, although only a small number of species reside in the oceans. The life cycles of insects vary but most insects hatch from eggs.Aitor: Adult insects typically move about by walking, flying, or sometimes swimming. Insects are the only invertebrates to have evolved flight. Some species, such as water striders, are capable of walking on the surface of water. Insects are mostly solitary, but some, such as certain bees, ants and termites, are social and live in large, well-organized colonies.Zelin: Some insects, such as earwigs, show maternal care, guarding their eggs and young. Insects can communicate with each other in a variety of ways. Male moths can sense the pheromones of female moths over great distances. Oihana:Most of the insects feed on the sap of trees, flowers nectar or pollen, dead animals, and even other insects, have a wide gamma of food, and even a come be a pest in crops such as lobsters, do not think mosquitoes aliemntan blood, they like others feed on plant juices, females are the only itching to get blood from warm-blooded mammals to fertilize their eggs.Maria Pia: The sexes are separate in insects, and reproduction is usually sexual, although in many insect groups eggs sometimes develop without fertilization by sperm. In some insects, such as bees, unfertilized eggs become males and fertilized eggs females. In others, such as aphids, all-female generations are produced by parthenogenesis. Yadira: Eggs are usually laid in a sheltered place; in a few insects they are retained and hatched internally. After hatching, the insect must molt periodically as it grows, since the rigid exoskeleton does not allow much expansion. A new, soft exoskeleton forms beneath the old one, and after each molt the insect undergoes a rapid expansion before its new covering hardens.

BIRDSAitor: Birds are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates. Modern birds are characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Zelin : Wings are evolved forelimbs, and most bird species can fly. Flightless birds include ratites, penguins. Some species of birds, are adapted to swim. Birds also have digestive and respiratory systems that are uniquely adapted for flight. Many species annually migrate great distances, and many more perform shorter irregular movements.Maria Pia :The semillvoras birds, also called seed-eaters consume seeds of grasses and other herbs such as rice and corn. Usually supplement their diet with fruits and insects . The nectar-feeding birds base most of their diet on nectar from flowers , which pollinate while obtaining their food plants. Oihana: The plants give fruits rich in carbohydrates (energy) and birds make them the "favor" to disperse their seeds to sites where new plants will grow. Carnivorous birds feed on other vertebrates. They represent a "nightmare" for many animals
