Food Chain Zoo Biology Food Pyramid Stok Vektr Telifsiz 2162598823 Biology Diagrams All living things are in a food chain.For example, zebras eat plants and grasses. Lions eat the zebras. Lions, zebras, and plants all belong to one food chain. Other animals eat zebras, too. Other animals eat the same plants.They all form different food chains.Put together, these food chains are called a food web. Trophic Levels Food chains have different levels.
A food chain refers to a linear sequence of organisms showing how energy or nutrient flows through an ecosystem when one organism consumes another for its survival.It provides information about which species eats which other species in nature. Typically, a food chain is represented by a diagram where arrows show the direction of energy and nutrients flow. 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.

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.
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.
African Grassland (Savanna) Food Web Biology Diagrams
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 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.
