The actors involved in the agro-food chain (farmers, processing, distribution and retail industries, consumers) take decisions that feed back into the different components of the food chain as well as into the agroecosystem within which they are embedded. In the light of global warming and ...
5.1.4 Describe what is meant by a food chain, giving three examples, each with at least three linkages (four organisms). A food chain shows the direction of energy flow from one species to another. For example, an arrow from A to B means that A is being eaten by B and therefore ind...
too low, it will bring huge problems to all sea life. Many believe that sharks can never be endangered as they are the strongest in their food chain. But the f 17 is that around 70million sharks are caught and traded in this industry every year. A u 18 says the numbers of som...

aThe food chain concept is useful for tracing and energy flow in an ecosystem, but simple food chains rarely exist by themselves. 食物链概念为追踪和能流是有用的在生态系,但简单的食物链独自很少存在。[translate]
Decomposers are the last group of organisms through which energy flows through. They consume the droppings and carcasses of all living things. Look at the figure below. It shows a simple diagram of a food chain and the flow of energy and nutrients. It starts with the producers, such as pla...
food. Primary consumers eat producers and secondary consumers eat primary consumers. Secondary consumers are eaten by tertiary consumers, who are the top of the food chain. Energy is lost at each trophic level of a food chain. As a result, there are fewer organisms per level moving up the ...
