19 Οκτ 2023 · Marine Food Pyramid. 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.
These levels can be illustrated in a trophic pyramid where organisms are grouped by the role they play in the food web. For example, the 1st level forms the base of the pyramid and is made up of producers.
Habitats lead to variations in food webs. Networks of trophic interactions can also provide a lot of information about the functioning of marine ecosystems. Compared to terrestrial environments, marine environments have biomass pyramids which are inverted at the base.
4 Οκτ 2024 · Marine food webs describe the linkages between all living organisms found in the marine environment, where every plant and animal species depends on another plant or animal species for its survival. This interdependency can be explored in predator–prey relationships or food chains.
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.
19 Οκτ 2023 · Algae and plankton are the main producers in marine ecosystems. Tiny shrimp called krill eat the microscopic plankton. The largest animal on Earth, the blue whale, preys on thousands of tons of krill every day.
12 Φεβ 2003 · Over 100 food webs have been published for marine ecosystems to describe the transfer of food energy from its source in plants, through herbivores, to carnivores and higher order predators.
