A food chain refers to the sequence of events in an ecosystem in which one living organism consumes another, which is then consumed by a larger organism. A food chain is the movement of nutrients and energy from one creature to another at different trophic levels. The energy that is passed along a food chain as one organism eats another is made by producers, which have the unique ability to turn inorganic compounds into organic compounds. All living things on Earth depend on this. Some of the most unusual food chains in the world are those of the Brazilian maned wolf, which eats mostly plants and fruit, and the Blue Whale, which is the biggest animal in the world but only eats krill, a tiny sea creature that looks like a small shrimp. Studies of the food chain are an important part of ecotoxicology studies, which look at how pollutants move through the environment and how they affect living things.
During energy transfer in the food chain, about 90% of the energy that could be used is lost. Only 10% of the energy that is available is passed on to the next level. The rest of the energy leaves the food chain in one of several ways:Organisms that eat other organisms are called consumers. The first organism in a food chain is the only one that doesn’t eat. The sun is the most important source of energy, and plants use sunlight to make food through a process called photosynthesis. The food chain is a straight succession of creatures in which nutrients and energy are passed from one to the next. There are two kinds of food chains: the one that starts with trash and the one that starts with grass. Let’s take a closer look at them: 1. Detritus food chain A food web is a natural interconnected food chains that represents the complex relationships between producers, consumers, and decomposers. 2. What is food chain?
Each of the above groups is called a “trophic level,” and it shows how many energy and nutrient transfers, or “consumption steps,” are between an organism and the energy source that started the food chain, such as light. As we’ll see below, it’s not always easy to put organisms in the right trophic level. People are omnivores, which means they can eat both plants and animals. What is Food Web? https://www.khanacademy.org/science/ap-biology/ecology-ap/energy-flow-through-ecosystems/a/food-chains-food-websLions, tigers, sharks, and eagles are all examples of carnivores. Cows, sheep, rabbits, zebras, antelope, and giraffes are all herbivores. People, bears, pigs, and dogs are all examples of omnivores. Raccoons, hyenas, and vultures are all examples of scavengers. In the 10th century, a scientist and philosopher named Al-Jahiz came up with the idea of the food chain. In 1927, Charles Elton wrote a book that popularised Al-ideas Jahiz’s and also came up with the idea of the food web. A food web shows how all the food chains in a certain area connect to each other. Consumers are living organisms that cannot produce their own food and obtain energy by consuming other organisms. For example, lions, tigers, wolves, foxes, etc. Since energy is lost when energy is passed along the food chain, The number of links and levels in an ecosystem can only go up to a certain point. It also means that animals at the top of the food chain need to eat and drink more to stay healthy. Food Chain Examples Autotrophs are living things that make their own organic molecules. Heterotrophs, which eat other organisms, get their organic molecules from the food they eat.
In this case, herbivores are called “primary consumers,” while carnivores are called “secondary consumers.” Organisms that eat producers make up the second level of the food chain. So, the second trophic level is made up of organisms that are primary consumers or herbivores. Food chains Description Algae or water plants can be the producers in a pond ecosystem. Small insects or fish eat these plants and algae. Large fish eat these small insects or fish. Then, birds or animals that eat fish will eat big fish, creating a chain. Another important part of the food chain is another kind of living thing. These are decomposers, which eat dead organic matter and break it down to make soil. Without decomposers, many ecosystems would not exist. This is because plants get nutrients from the soil, which starts the process over again. There are more than 100,000 different kinds of decomposers, such as bacteria, fungi, and worms. Secondary consumers are the things that eat the primary consumers. Most secondary consumers are carnivores, or people who eat meat.From food webs and food chains worksheets to printables that will help your students follow producers, consumers, and decomposers through the ecosystem, this curated library of printables and Google Slides templates has been created by teachers for teachers. Food Chain + Food Web Lesson Planning The food chain and food webs form the basic structures that determine the interactions between species and the flow of energy and nutrients within ecological communities. It holds several significance, including: Another way to use the Food Chain Pictures is for a display. Why not hang them up around your classroom, they’ll brighten up your room and also be there as a point of reference for the children. Have a look at our Food Chains Display Banner or Food Chain Display Letteringthat you can add to your display! The food chain describes who eats who in the wild. Every living thing needs food to survive, so a food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. Each link in the chain is for the next link. Producers: Phytoplankton, cyanobacteria, algae, and green plants are all examples of producers in a food chain. This is the first link in a chain of food. The first step in a food chain is the producers. The farmers make food by using the energy from the sun. Autotrophs are another name for producers because they make their own food. Producers are plants and other living things that make their own food through a process called photosynthesis.
