Noun an example of a food web is a diagram that shows a bird may eat a mous. Food web in any ecosystem there are many food chains and generally most plants and animals are part of several chains.
How food chains and food webs represent the flow of energy and matter. Trophic levels and efficiency of energy transfer. The food web is defined as a concept that all the predator prey interactions in a community are interrelated and are sometimes drawn in a web like image.
Green plants are autotrophic meaning they create their own food using a chemical reaction called photosynthesisduring photosynthesis plants take carbon dioxide from the air and water from the ground through their roots which react to produce glucose and oxygen. Marine food webs are usually longer than terrestrial food webs. How food chains and food webs represent the flow of energy and matter.
The zebra in a food web is 3rd in a food web because first example there is the sunthen the grass then the herbavores vegatariansother examples along with the zebra are horsescowszebras. All plants and animals are part of a food chain. Links higher up in the food chain rely on the lower links.

Scientists estimate that if there are a million producers algae phytoplankton and sea grass in a food web there may only be 10000 herbivores.
