Building a food web

A food chain is an organized series of living things linked together by an alimentary (food related) relationship. Animals draw the energy needed for survival from their food. At the base of such a chain one finds the producers. These are terrestrial plants or aquatic ones (algae, phytoplankton). They make their own organic matter from nutrients, CO 2, and light (photosynthesis). The animals situated one step up on the chain are the first level consumers: the herbivores. They are the prey of the second level consumers: the carnivores. A carnivore that doesn’t have any predators is called an apex predator. These are situated at the top of the chain. An arrow stands for “…is eaten by…”. A food chain is made up of links that can also be part of other chains. They are branches of a vast alimentary network. This animation omits the role of decomposers. These are organisms and microorganisms that degrade dead organic matter (wastes, dead plants and animals). They provide the larger part of the nutrients that are recycled by the producers. Draw an arrow between 2 images meaning "... is eaten by ...". There are 25 arrows to be placed to complete the game. Once completed, you will be requested to drag the images in their appropriate category (producer, consumer,...).

Food Webs

A food web is all of the interactions between the species within a community that involve the transfer of energy through consumption. A food web incorporates different food chains within an environment. These types of interactions occur between producer and consumer, and between predator and prey. The transfer of energy starts with plants. Plants are able to convert sunlight into a chemical form of energy through the process of photosynthesis. One of the end products of photosynthesis is glucose, a sugar in which energy is stored. Plants are called producers because they produce their own energy without consuming another organism. Animals are called consumers; they must consume plants and other animals to obtain energy. Animals that feed only on plants are called herbivores, or primary consumers, since they eat producers. Animals that feed on other animals are called carnivores. They are called secondary consumers if they eat primary consumers. Another kind of secondary consumer is an omnivore, which is an animal that feeds on both plants and other animals. Any animal that hunts and feeds on other animals is called a predator, and the animals that predators feed on are called prey. All carnivores are predators, and herbivores—and sometimes omnivores or other carnivores—are their prey. Energy moves up a food chain, starting with plants, then moving up through herbivores, and then carnivores. A fourth group of organisms called decomposers breaks down the organic matter left ...

A food chain is a linear network of links in a Food chains were first introduced by the Arab scientist and philosopher A common metric used to quantify food web trophic structure is food chain length. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web. The mean chain length of an entire web is the arithmetic average of the lengths of all chains in the food web. Food chains are very important for the survival of most species. When only one element is removed from the food chain it can result in extinction of a species in some cases. The foundation of the food chain consists of Many food webs ha...

What is a Food Chain?

A food chain shows the interrelationships between producers and consumers by illustrating how energy is exchanged as one organism eats another. Discover how food chains work, check out the different trophic levels in a food chain, and explore some examples of food chains to understand the pathway of energy transfer among organisms. Updated: 09/09/2021 A food chain is a pathway that represents the exchange of energy from one organism to another. In other words, it is the chronological order of who eats whom in a biological community. Food chains go hand-in-hand with food webs, though there are differences between the two. While a food chain is a single pathway of energy transfer, a food web shows all of the different relationships or possible energy transfers between a selected group of species. Every biological community can have multiple and diverse food chains, but every food chain starts with a primary source of energy. The most obvious source of energy is the big ball in the sky, the sun. Other food chains may start with a boiling-hot deep sea vent as a source of energy. The next organism to benefit off of this initial source is called the primary producer. These are organisms that can create their own food from the main energy source. Some examples include plants and algae. For example, plants are a primary producer because they can harness and use the energy from the sun through a process called photosynthesis. Here are some graphics examples of food chains. Please n...

Food chains & food webs (article)

Organisms of different species can interact in many ways. They can compete, or they can be symbionts (long-term partners with a close association). Or, of course, they can do what we so often see in nature programs: one of them can eat the other. (Chomp!) That is, they can form one of the links in a food chain. 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: grass → \rightarrow → right arrow cow → \rightarrow → right arrow human. But what if you had lettuce on your hamburger? In that case, you're also part of a food chain that looks like: lettuce → \rightarrow → right arrow human. As this example illustrates, we can't always fully describe what an organism (such as a human) eats with one linear pathway. For situations like that, we may want to use a food web, which consists of many intersecting food chains and represents the different things an organism can eat, and be eaten by. Autotrophs are the foundation of every ecosystem on the planet. That may sound dramatic, but it's no exaggeration! Autotrophs form the base of food chains and food webs, and the energy they capture from light or chemicals sustains all the other organisms in the community. When we're talking about their role in food chains, we can call autotrophs producers. Heterotrophs (“other-feeders”) such as humans can't capture light o...

Omnivorous animals have a set of flat and sharp teeth to help them digest meat, fruit, and Trophic level Trophic levels can be understood as the position of an organism in a food chain. The levels under the trophic levels are namely- producer, consumer, and decomposer. Producers The producers in a food chain include all autotrophs such as phytoplankton, cyanobacteria, algae, and green plants. This is the first stage in a food chain. The producers occupy the first level of the chain. The producers are autotrophs (organisms that make their food). Producers are any plant or other organisms that produce their nutrients through photosynthesis. These organisms make their food by using light energy provided by the sun and turning it into energy. They are the first level of every food chain as they make their food.

food chain

The term food chain describes the order in which organisms, or Most food chains start with organisms that make their own food, such as plants. Scientists call them producers. Organisms that eat other living things are known as consumers. A squirrel that feeds on plants is called a primary consumer. A hawk that eats the squirrel and other primary consumers is called a secondary consumer. Decomposers are often the final link in a food chain. Decomposers are bacteria and other organisms that cause decay. When plants and animals die, decomposers break down their tissues. This adds nutrients to the soil so that new plants may grow. Then the food chain begins again. A food web is a group of food chains within an ecosystem. Most living things eat more than one type of animal or plant. So their food chains overlap and connect. For example, the hawk that ate the squirrel also may eat fish. This makes the hawk a part of two food chains, or a food web. • The same safe and trusted content for explorers of all ages. • Accessible across all of today's devices: phones, tablets, and desktops. • Improved homework resources designed to support a variety of curriculum subjects and standards. • A new, third level of content, designed specially to meet the advanced needs of the sophisticated scholar. • And so much more!
