Part 1: Complete a Food Web. You learned in the previous activity that energy from the sun is accumulated by primary producers and then flows up trophic levels to each of the consumers in a food chain. In this exercise, you will draw arrows in the direction of energy flow within a food web.
Food Webs. A food web represents multiple pathways through which energy and matter flow through an ecosystem. It includes many intersecting food chains. It demonstrates that most organisms eat, and are eaten, by more than one species. Examples are shown in Figures below and below. Food Web. This food web consists of several different food chains.
global population should eat exactly the same food, nor does it prescribe an exact diet. Instead, the planetary health diet outlines empirical food groups and ranges of food intakes, which combined in a diet, would optimize human health.
