A food web diagram illustrates ‘what eats what’ in a particular habitat. Pictures represent the organisms that make up the food web, and their feeding relationships are typically shown with arrows. The arrows represent the transfer of energy and always point from the organism being eaten to the one that is doing the eating. Trophic levels
An in situ perspective of a deep pelagic food web derived from ROV-based observations of feeding, as represented by 20 broad taxonomic groupings. The linkages between predator to prey are coloured according to predator group origin, and loops indicate within-group feeding.
1 Φεβ 2019 · Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly. Phytoplankton and algae form the bases of aquatic food webs.
9 Οκτ 2009 · This conceptual animation illustrates some of the ecological pathways between species within the marine ecosystem. Single-celled microscopic plants called phytoplankton float in the upper ocean. These photosynthetic plants form the foundation of the marine food web, and nearly all life in the ocean depend upon them for survival, including ...
19 Οκτ 2023 · This food pyramid displays a basic marine food web. Organisms on the first trophic level, such as plants and algae, are consumed by organisms on the second trophic level, such as conchs and blue tangs. At the top of the food web is an apex predator, a shark. Illustration by Tim Gunther.
19 Οκτ 2023 · There are other deep-ocean ecosystems that are entirely independent of the sunlight energy that kick-starts the main marine ecosystem. At their roots, these unique ecosystems are fueled by chemical energy, which enters the ocean from sources like seafloor hydrothermal vents .
9 Σεπ 2024 · Explain to students that, in a single drop of salt water, thousands of microbes (tiny organisms), including bacteria and phytoplankton (tiny floating plants), are interacting to form the base of the food web for the entire ocean.
