-cause and effect-
Butterflies are found on every continent but Antartica. The U. S. alone is home to about 700 different species of this beautiful and loved insect. Butterflies play a number of roles in the ecosystem. They act as pollinators and food sources for other species, acting as an important connectors in a thriving ecosystem web.
¨ ¨ Nearly 90 percent of all plants need a pollinator to reproduce, and as bee populations drop, the role of the butterfly becomes even more vital. Without these wonderful insects, many plant species would then be unable to reproduce and their populations would dramatically decrease without the butterfly’s presence. We would see this effect in a number of plant species, including wildflowers we have grown to love. This loss of plant life would affect both animals and humans.¨ This is just one reason why butterflies are very important to the environment; pants rely mainly on the butterflies to pollinate them so they can reproduce and produce more seeds and create food.Butterflies also provide assistance for genetic variation in the plant species that they collect nectar from. Many species of butterflies migrate over long distances, which allows pollen to be shared across groups of plants that are far apart from one another. This helps plants to be more resilient against disease and gives them a better chance at survival.
Butterflies not only help the producers but they also help the consumers.They provide a hearty meal for animals,including birds and mice.As butterfly populations decrease, so will populations of birds and other animals that rely on them as a food source. This loss of the butterfly is the beginning of the “butterfly effect.”As the butterflies decrease it will continue to affect the ecosystem in a very harmful way. ¨¨¨¨¨¨¨¨¨¨¨¨
¨ Nearly two-thirds of all invertebrates can be connected back to the butterfly on the food chain. The loss of this seemingly insignificant insect could potentially collapse entire ecosystems that rely so heavily on them.¨
Can we live without butterflies??Would we survive??
Bees, butterflies and beetles pollinate plants, and provide a critical protein source for species up the food chain. The United States Forest Service puts it simply: “Without pollinators, the human race and all of earth’s terrestrial ecosystems would not survive.”
