How humans have an impact on the environment. research either a food chain or food web that naturally exists in the ecosystem and describe the negative impacts that could happen to one or more species if humans continue to interact negatively with the environment.

When pollution is lethal or toxic to animals, the deaths of those animals impact the diversity of an ecosystem. The death of even the smallest organisms in an environment can make a big impact. For example, if pollution kills natural forest decomposes like bacteria and fungus the ecosystem may lack the means to break down organic materials on the forest floor. If the organic material doesn’t decompose, the soil may not receive the nutrients it needs to encourage the growth of plants on which herbivores and omnivores depend. Even the loss of an insect can disrupt an entire food web. In the 2010 article "High Levels of Miticides and Agrochemicals in North American Apiaries: Implications for Honey Bee Health," found on the PLOS ONE website, researchers reported that pesticides had a role in the deaths of over 30 percent of the honeybees in the United States between 2006 and 2009. Without honeybees, lack of pollination services would decrease the amount of fruits, vegetables and berries available for humans and animals to eat.
