Detailed explanation-1: -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.
Detailed explanation-2: -Extinctions and Disruptions If one species in the food web ceases to exist, one or more members in the rest of the chain could cease to exist too. A plant or animal doesn’t even have to become extinct to affect one of its predators.
Detailed explanation-3: -If the plants or other producers of an ecosystem were removed, there would be no way for energy to enter the food web, and the ecological community would collapse.
Detailed explanation-4: -As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey’s population can proliferate, unbalancing local ecosystems.
Detailed explanation-5: -If resources are destroyed, the ecosystem will not be able to support a large population. This causes the carrying capacity to decrease. Humans can also alter carrying capacity.
