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>

<h2>Explanation:</h2>
Energy production needs a source. These sources may be renewable or non renewable but in both cases they are present naturally in the universe and we cannot make anything without using natural resources. For example if we use nuclear energy we need radioactive minerals. Similarly water, air, solar energy, coal, fossil fuels, natural gas or whatever source we take, they are all present in nature already so natural resources are required for all energy producing technology whatever the industry we take.

Answer:
Many human and physical factors affect population distribution and population density across the world. Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy.
Carbon fixation only takes place in autotrophs. For example plants, algae, and some bacteria, or organisms that make their own food.
