Food Chain Diagram Concept Illustration Stock Vector Royalty Free Biology Diagrams The diagram shows how mercury can accumulate in the food chain. In the sea, tiny animals and plants called plankton absorb the mercury compounds. When the plankton are eaten by small fish, the An arctic tundra food chain: Moss and Lichens (Producer) → Arctic Hare (Primary Consumer) → Arctic Fox (Secondary Consumer) → Polar Bear (Tertiary Consumer) Diving into Food Webs. While food chains provide a clear, linear model of energy flow, nature is far more complex. Food webs present a more accurate picture, showcasing the A food chain is a straight or linear energy flow from one organism to another. Each species or organism is allocated a trophic level. For example, the primary producers or plants are at trophic level 1, while predators are at either trophic level 4 or 5. As such, a food web combines many different food chains.
A food chain describes how living organisms get their food. All organisms, from the most complex to the most simple ones, need food to survive. Living things can be part of multiple food chains and all connected food chains in an ecosystem combine to make a food web.. As shown in the infographic below, a basic food chain is composed of producers, consumers, and decomposers.

zebra = primary consumer; lion = secondary consumer; Energy is Lost Like we said above, all the energy made in the food chain comes from the producers, or plants, converting sunlight into energy with photosynthesis. The rest of the food chain just uses energy. So as you move through the food chain there is less and less energy available. A food web is similar to a food chain, but the food web is comparatively larger than a food chain. Occasionally, a single organism is consumed by many predators, or it consumes several other organisms. Due to this, many trophic levels get interconnected. The food chain fails to showcase the flow of energy in the right way. 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
This type of food chain is common in ecosystems where parasites play a significant role in controlling populations of other organisms. Examples of Food Chain. In the above food chain, there were three organisms involved: Grass, Deer, and Lion, so it is said to be a food chain having three steps or three links.
