A food chain shows the feeding relationship between different living things in a particular environment or habitat. Often, a plant will begin a food chain because it can make its own food using energy from the sun. Similarities between Food Chain and Food Web. Also, a food chain represents a series of events in which food and energy are transferred from one organism in an ecosystem to another. Ecological community is the collection of individuals belonging to different species, occupying the same habitat, at the same time. Difference between food chain and food web is mainly due to the following factors: Network of links : Food chain is an one-way pathway that includes a linear network of linking organisms. Differences Between A Food Chain And A Food Web. The flow of food is from one organism to another. The food chain is the sequence of organisms in which each organism eats the lower member and itself is eaten by a higher member. In ecology, the food chain is the series of transfer of matter and energy from organisms to organisms in the form of food. For example, the difference between predator food chain and a parasite food chain is that, in the latter chain, orga­nisms are smaller and smaller instead of being generally larger and larger. The main difference in the case of food webs would be that there are several lines branching from each species, as opposed to one or two in the case of food chains. Main Difference. A. Grazing food chain: Member of higher trophic level feed upon many organisms This is a ASSURE lesson plan on the ocean food web for 5th grade. In contrast, a food web is a complex pathway that indicates a number of food chains together to show how the organisms are interlinked with each other to survive. Food Chain. The food chain starts with the producer or plants that convert solar energy into the usable form of energy (food) by the process of photosynthesis which is … The interaction between these individuals for their survival gives rise to various food chains, which ultimately give rise to various food webs. It refers to a natural system by which energy is transmitted from one organism to another. Simply put, a food web describes all of the food chains in a given ecosystem. Individual and separated food chains have a higher chance of having instabilities in the ecosystem for the case of the food chain. Member of higher trophic level feed upon a single type of organism. However, for the food web, the ecosystem is made much more stable due to the presence of multiple interconnected food chains. Food web. It consists of a number of interconnected food chains. So, a series or chain of organisms in which each of them depends on one and other as a source of food or energy is called a food chain, whereas food web is a system of many food chains that are dependent on each other for the source of food. Before we look at the difference Between Food Chain and Food Web, let’s understand what is a food web: A food chain is a linear flow of energy and nutrients from one organism to another. Difference Between Food Chain and Food Web What is Food Chain. The food chain describes which organism in the environment eats another organism. Food Webs .

Types of Food Chain: Food chains are of two basic types: A. Grazing food chain, and B. Detritus food chain. Food is the basic source of energy for all organisms in the ecosystem. Each organism sits at a particular trophic level; for instance, the primary producers such as grass sit at trophic level 1 and the apex predators sit at trophic level 4 or 5. Rather than forming a straight line that goes from the sun to the plants to the animals that eat them, food webs show the interconnectedness of all of the living creatures in an ecosystem.
