Examples of Food Chains
The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whale s—needs food to survive. Each food chain is a possible pathway that energy and nutrient s can follow through the ecosystem. For example, grass produces its own food from sunlight. A rabbit eats the grass.
A food chain is a linear network of links in a food web starting from producer organisms such as grass or trees which use radiation from the Sun to make their food and ending at apex predator species like grizzly bears or killer whales , detritivores like earthworms or woodlice , or decomposer species such as fungi or bacteria. A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level. A food chain differs from a food web, because the complex network of different animals ' feeding relations are aggregated and the chain only follows a direct, linear pathway of one animal at a time. Natural interconnections between food chains make it a food web.
A food chain is a linear network of links in a food web starting from producer organisms and equivalently, sequences of links that start with basal species, such as producers or fine organic matter, and end with consumer organisms. Food.

If you're like most kids, you probably hunt for most of your food in the aisles of your local grocery store. If you're hungry for some crunchy green vegetables, you can head over to the produce aisle and stalk some wild celery. Or if pizza sounds good, you can hide out in the frozen food aisle until just the right moment to snatch that frozen pizza from the freezer! In many places around the world — and for wild animals — finding food to sustain life is not nearly as easy as a trip to the supermarket. In the wild, it often comes down to a simple question: are you predator or prey? And the answer is sometimes both!
Students will learn about food chains , pyramids, and food webs. Students will also learn how all of nature is connected and dependent on each other. A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees and shrubs, the giraffes that eat trees and shrubs , and the lions that eat the giraffes. Each link in this chain is food for the next link. All food chains start with energy from the sun.
Every organism needs to obtain energy in order to live. For example, plants get energy from the sun, some animals eat plants, and some animals eat other animals. A food chain is the sequence of who eats whom in a biological community an ecosystem to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The next link in the chain is an organism that make its own food from the primary energy source -- an example is photosynthetic plants that make their own food from sunlight using a process called photosynthesis and chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents. These are called autotrophs or primary producers. Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers -- an example is a rabbit that eats grass.
