Furthermore, a food web is a more realistic representation of the energy flow within each component of the ecosystem when compared to a food chain. Food chain and food web are two types of ecological concepts that interpret the flow of energy in a particular ecosystem.

Food chains show how energy passes through an ecosystem. When one organism is eaten by another, most of the energy is lost and a little bit gets transferred to the consumer. These feeding orders are needed to maintain a delicate balance in the environment. Each member of the food chain helps keep population sizes within the carrying capacity. If any part of the chain were damaged, the entire ecosystem would be in trouble. Food chains and food webs are two ways that ecologists can show how energy is transferred between organisms within an ecosystem.

Difference Between Food Chain and Food Web

A food web or food cycle is the natural interconnection of food chains and a graphical representation usually an image of what-eats-what in an ecological community. Another name for food web is consumer-resource system. Ecologists can broadly lump all life forms into one of two categories called trophic levels : 1 the autotrophs , and 2 the heterotrophs. To maintain their bodies, grow, develop, and to reproduce , autotrophs produce organic matter from inorganic substances, including both minerals and gases such as carbon dioxide. These chemical reactions require energy , which mainly comes from the Sun and largely by photosynthesis , although a very small amount comes from bioelectrogenesis in wetlands, [1] and mineral electron donors in hydrothermal vents and hot springs.

Food chains and food webs are easy to get confused since they both show the movement of energy through an ecosystem. But, while a food chain only shows a singular path, the food web shows how the paths are connected. Learn other differences between a food chain and a food web by looking at each one. Get examples of how a food chain and food web work. In the simplest terms, a food chain shows you the movement of energy from producers to consumers. For example, a plant uses photosynthesis to make energy.

Food Chains and Webs

Green plants make their own food. They use the energy from the sun to make their own food. Some of this food is used, and some is stored in the roots, stems, and leaves. All living things need food to give them the energy to grow and move.

Food chain The food chain is an ideal representation of flow of energy in the ecosystem. In food chain, the plants or producers are consumed by only the primary consumers, primary consumers are fed by only the secondary consumers and so on. The producers that are capable to produce their own food are called autotrophs.

Это пугало Хейла. Он понимал, что времени у него. Агенты могут появиться в любую минуту. Собрав все силы, Хейл, сильнее обхватив Сьюзан за талию, начал пятясь подниматься по лестнице. Она пыталась цепляться каблуками за ступеньки, чтобы помешать ему, но все было бесполезно. Он был гораздо сильнее, и ему легче было бы подталкивать ее вверх, тем более что площадка подсвечивалась мерцанием мониторов в кабинете Стратмора. Но если она окажется впереди, он подставит Стратмору спину.

Сьюзан отпила глоток чая и промолчала. Хейл пожал плечами и направился к буфету. Буфет всегда был его первой остановкой. Попутно он бросил жадный взгляд на ноги Сьюзан, которые та вытянула под рабочим столом, и тяжело вздохнул. Сьюзан, не поднимая глаз, поджала ноги и продолжала следить за монитором.

На этот раз ему очень вежливо ответили по-немецки, но снова сказали, что рыжих девочек у них. - Keine Rotkopfe, простите.  - Женщина положила трубку. Вторая попытка также ни к чему не привела. Беккер заглянул в телефонный справочник. Оставался последний номер.

Тела танцующих слились так плотно, что он не мог рассмотреть, во что они одеты. Британского флага нигде не было. Ясно, что ему не удастся влиться в это море, которое раздавит его, как утлую лодчонку. Рядом с ним кого-то рвало.

Food web , on the other hand, is defined as the convoluted or complicated pathway of an ecosystem consist of numerous food chains of the different trophic level, through which the energy flow.

A food chain follows one path of energy and materials between species.
