Do you think you know which species are most vulnerable in an ecosystem? A novel analytical method developed by Italian ...

A food web is a diagram showing an ecosystem's complex feeding relationships. Learn about types of food webs and how they differ from a food chain.

Food-web theory can be a powerful guide to the management of complex ecosystems. However, we show that indices of species importance common in food-web and network theory can be a poor guide to ...

Understand the basics of how energy moves through an ecosystem by learning about the food web and the different classifications organisms in the web.

The feeding interactions represented by the food web may have profound effects on species richness of community, and ecosystem productivity and stability (Ricklefs 2008).

Food chains show interconnected food webs. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

Every living thing plays a role in the food chain and Earth’s ecosystems, and the extinction of certain species, whether predators or prey, can leave behind significant impacts.

Researchers invert a classical approach to modeling food webs. Instead of trying to replicate stable, complex ecosystems using simplistic representations of species interactions, the authors ...

But changes to the food web aren’t the primary problem for human populations; the effects on ecosystem processes are often more dangerous.
