  7. 7. Water Cycle The water cycle is also known as the hydrological cycle. There is the same amount ofwater on the Earth now as there was when the Earth began. The water cycle is how theearths water recycles itself. First water molecules from lakes, rivers, streams, reservoirs, and the sea get heatedup by the sun and then turn into vapour that rises into the air. Next, these water molecules form into clouds, this is because a process calledcondensation occurs. When the air and the water cool, they form drops of water whichthen fall to the earth as rain. If they are frozen, they become snow or sleet. Once the water reaches the ground, it can flow across the land until it reaches rivers,lakes, streams, or the sea. It can also sink into the ground and flow because of gravitythrough gaps in rock, gravel and sand. Because of this, it reaches these bodies of watertoo. Now the cycle begins again, when water is evaporated once more.
  8. 8. MOSQUITO LIFE CYCLEAll mosquitoes must have water in which tocomplete their life cycle. This water can range inquality from melted snow water to sewage effluentand it can be in any container imaginable. Thetype of water in which the mosquito larvae is foundcan be an aid to the identification of which speciesit may be. Also, the adult mosquitoes show a verydistinct preference for the types of sources inwhich to lay their eggs. They lay their eggs in suchplaces such as tree holes that periodically holdwater, tide water pools in salt marshes, sewageeffluent ponds, irrigated pastures, rain waterponds, etc. Each species therefore has uniqueenvironmental requirements for the maintenanceof its life cycle.

  11. 11. The Life Cycle of Fr og Metamorphosis is a transformation or you can say different stages of development of each andevery insect before it becomes an adult. Here we are talking about butterfly metamorphosis. Butterflymetamorphosis divided into four stages. The first stage of butterfly metamorphosis is egg phase. Female butterflies lay their eggs on theleaf. Female butterflies choose what kind of the plant for their eggs. Some caterpillar are needs specificplant for their live. The butterfly eggs, need almost a week for hatch. The larva develop in the egg they makea small hole in the egg and emerges on the leaf. Here the second stage begins. The larva of butterfly is called caterpillar. Caterpillar grows fast by feeding on the leaves. In twoweeks they become adult caterpillar. The fully grown adult caterpillar , start crawling away from the plant itwas feeding on and keeps crawling until it found safe haven to pupate. Once caterpillar pupate, it makes asilk-like mat on surface and hangs upside down. Caterpillar sheds its skin for the last time before it movesinto the next stage of butterfly metamorphosis. When the larva enters the third phase. The skin of the caterpillar is shed for the final time. Thepupate of a butterfly is otherwise known as chrysalis. Within the chrysalis the caterpillar slowly turns into abutterfly. The body parts of the caterpillar disintegrate to form the body parts of the butterfly. Thetransformation period of chrysalis to butterfly takes around 10 to 15 days. The hardened chrysalis cracks and the butterfly emerges from it. The wings of the butterfly aresmall and wet. Because of that the wings are wet and the butterfly is unable to fly. However, within an hourthe wings become dry and the butterfly is ready to fly. The butterfly metamorphosis, butterflies are one of the beautiful creations among the insects.Children and adults enjoy their beauty equally. The female butterfly is ready to mate within four to five daysafter it emerges from chrysalis. Butterfly metamorphosis is a vicious cycle and the life of the butterfly goeson and on.
