For the answer to the question above asking what does the pyramid of biological magnification. Biomagnification, also known as amplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain. <span>DDT was a commonly-used pesticide before its dangers became known. In some aquatic ecosystems, organisms from each trophic level consumed many organisms of the lower level, which caused DDT to increase in birds (apex consumers) that ate fish.</span>
Answer:
One: the greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.
<em>The greenhouse effect occurs naturally. Lately the greenhouse effect has been magnified due to greenhouse gases emitted into the atmosphere by humans. and global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. </em>
<em>Global warming refers to the increase in annual average temperatures across the globe. As the amount of greenhouse gases in the atmosphere increases, the planet becomes warmer and warmer on average. </em>

Three: fossil fuels like coal oil and natural gasses
<em>Answer:</em>
