the food chain If you hunt too much of one animal, it will affect what the other animals eat, as you are affecting the numbers in a food chain. Plus, if a lot of animals were hunted, leaving only a few left, the animals in the food chain would eat the rest of the species, causing extinction.Click to see full answer. Simply so, what are the effects of over hunting?Over hunting will cause the decline in the particular animals species, this will effect everything around it, for example other animals, plants and trees. It directly affects the natural environment in that it throws off natural predation and population growth of the wildlife.Likewise, what happens when the food chain is disrupted? 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. The U.S. Geological Survey notes that this decline probably caused the fish to go extinct. Likewise, people ask, how humans affect the food chain? Humans are dominant consumers. They affect food webs through energy production and agriculture, pollution, habitat destruction, overfishing and hunting. Also their demands for food and shelter along with population growth, affecting soil and aquatic ecosystems.How does poaching affect the food chain?Poaching can affect the environment by depleting certain species of animals. It causes animals that are endangered to become extinct, thus creating a disruption in the food chain. Eventually, it will cause as a result new adaptations of animals, and/or species beyond human control.
