Human involvement in food webs has been profound, bringing about enormous and disproportionate losses of large apex predators on land and in water. The losses have modified or even eliminated concatenations of indirect interactions propagating from predators to herbivores to plants, inter alia. Food webs are a synthesis of bottom-up ...This type of chain thus depends on autotrophic energy capture and the transfer of this captured energy to herbivores. Most of the ecosystems in nature exhibit this type of food chain. Examples of food chains in this category include: Phytoplankton -> zooplanktons -> Small fish -> Larger fish -> Birds -> Decomposer. This recording shows how plastic enters the food chain because arrow worms are in turn eaten by animals higher up the chain. Amphipods that live at the deepest point of the ocean, the eleven-kilometer-deep Mariana Trench, were examined for the presence of plastic. These animals all had plastic in their bodies, almost always microfibers from ... Get an overview of what a food chain is and learn about a lion's food chain.

At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other. To understand how this happens visit the link.“A great many of the health and environmental problems created by our food system owe to our attempts to oversimplify nature’s complexities, at both the growing and the eating ends of our food chain. At either end of any food chain you find a biological system- a patch of soil, a human body- and the health of one is connected- literally- to ... In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass → cow → human. On a scale of 1 to 5, with 1 being the score of a primary producer (a plant) and 5 being a pure apex predator (a animal that only eats meat and has few or no predators of its own, like a tiger, crocodile or boa constrictor), they found that based on diet, humans score a 2.21—roughly equal to an anchovy or pig.
