The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. This occurs when one organism consumes another organism. It This is an African Savanna Food Web. See if you can identify all the parts of the food web that make this a functioning, healthy ecosystem. Look for: The Producers - the trees, shrubs and grass. The Primary Consumers - the zebras and elephants. The Secondary Consumers - the cheetah, hyena. The Scavengers - the termites, vultures and hyena. The Decomposers or Detritivores - mushrooms
The food chain ensures the desert ecosystem remains functional despite limited resources and extreme conditions. Example: Scavengers like vultures clean up carrion, reducing disease spread and contributing to ecosystem health. All living things rely on each other in the food chain. Energy transfers through living organisms from predators, herbivores, producers and decomposers. Feeding relationships are often shown as simple food chains - in reality, these relationships are much more complex, and the term 'food web' more accurately shows the links between producers, consumers and decomposers A food web diagram illustrates 'what eats what' in a particular habitat. Pictures represent the organisms that make up the food web, and their feeding relationships are

Each level of a food chain is referred to as a trophic level. Food Chain diagram Features of Food Chain Most food chains start with the producers. Organisms that make their own food are called producers. Plants, phytoplankton, and organisms that look like plants, like algae, are all examples of producers. The food chain starts when these producers are eaten by other organisms. Some producers
Scavengers occupy a secondary-consumer position in the food chain, meaning that they consume animals that consume plants or other animals. Scavenger examples include hyenas, vultures and lobsters. Most scavengers feed primarily on meat, but some eat dead plants and some occasionally hunt live prey. The scavengers and decomposers form the final group of this food chain. Fungi, like mushrooms and some bacteria living in the soil, break down the dead bodies of plants and animals and release them into the soil. The producers use those resources to make their food, thus keeping the food chain running.
