Summary#5 Surviving in Ecosystems

Organisms can help or hinder the survival of other organisms. Animals are important because they control an population, some animals adapt to their environment like the polar bears because they have skin, fur, claws and other things that makes him to adapt to their environment, but if they go here to Panama they would die. Also, the penguins if they go to the desert they could die because they are not adapt to other environments. We don´t have fur or claws but we have the brain and intelligence to adapt and  know  what we have to do and we don´t use our instinct  like animals. Now we are going to talk about the symbiosis, the symbiosis is a relationship of two kinds of organisms over time.They are three types of symbiosis that are: mutualism, mutualism is two organisms benefit and helping by each other , one example is the yucca moth and the yucca tree, also commensalism, commensalism is two organisms one is benefit and the other is not harmed and not benefit, one example is the anemone and the clown fish, also the parasitism, parasitism is two organisms one is harmed and the other is benefit, one example is the flea and the dog also the human and mosquitoes.
