What do you understand by the adaptations in organisms and why do they adapt and types of organisms recycle nutrients in a food web?
One human physiological adaptation is the one where one sense becomes more powerfull when another sense fails. For example, when one person's vison begins to fail somewhat, his hearing becomes more powerfull to compensate for that. Involving the food chain, this becomes essential so that the raisin-grape vegetation to be a superfood for humans remains so for humans and not for squirrel mammalian animals or avian animals that try to eat it it. Thus, the acute hearing of the raisin-grape farmer can ward away the intruding animals when he hears them. This is the case of urban farming in English Canada.
An adaptation of an organism is the modification or change in the organism's body or behavior that helps it to survive. Animals adapt to their environment so that they can perform a task easily or to provide them with higher chances of survival.An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment. The type of organism that recycles nutrients in a food web is decomposers. Decomposers are organisms that consume dead or decaying matter and recycle the nutrients back into the soil. An adaptation is a change to the structure or behavior of the organism which helps the organism survives better in the habitat. This means the organism will have to adapt to the climatic conditions, predators and compete for the same resources with the other organisms living in that habitat. In a food web nutrients are recycled in the end by decomposers. Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients. Decomposers work at every level, setting free nutrients that form an essential part of the total food web.Decomposers, like fungi and bacteria, complete the food chain. Decomposers turn organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil. They complete the cycle of life, returning nutrients to the soil or oceans for use by autotrophs. Every organism follows this food chain by depending on another organism. If an organism is removed from the food chain, it spoils the flow of energy and nutrient in the ecosystem. It disrupts the balance of the food chain. As a result, the organisms which depend on others for food will die due to starvation. In some food webs, there is one critical "keystone species" upon which the entire system depends. In the same way that an arch collapses when the keystone is removed, an entire food chain can collapse if there is a decline in a keystone species.
