A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
An essential trace element is a dietary element, a mineral that is only needed in minute quantities for the proper growth, development, and physiology of the organism. [4] The essential trace elements are those that are required to perform vital metabolic activities in organisms. [ 5 ]
The microbial food web refers to the combined trophic interactions among microbes in aquatic environments. These microbes include viruses, bacteria, algae, heterotrophic protists (such as ciliates and flagellates). [1] In aquatic ecosystems, microbial food webs are essential because they form the basis for the cycling of nutrients and energy.
In yeast, few of the essential genes are duplicated within the genome: 8.5% of the non-essential genes, but only 1% of the essential genes have a homologue in the yeast genome. [ 59 ] In the worm C. elegans , non-essential genes are highly over-represented among duplicates, possibly because duplication of essential genes causes overexpression ...
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
A food pyramid and a corresponding food web, demonstrating some of the simpler patterns in a food web. A graphic representation of energy transfer between trophic layers in an ecosystem. Energy flow is the flow of energy through living things within an ecosystem . [ 1 ]

Winemiller has produced more than 280 scientific papers and 25 book chapters on topics ranging from food web ecology to the evolutionary ecology of fishes. He coauthored the books "The Science of Instream Flows: A Review of the Texas Instream Flow Program" (2005, National Academies Press) and "Peacock Bass: Diversity, Ecology and Conservation" (2021, with L.C. Kelso Winemiller and C.G ...
