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.
Generalized food web of waterbirds from Chesapeake Bay. A food web is the archetypal ecological network. Plants capture solar energy and use it to synthesize simple sugars during photosynthesis. As plants grow, they accumulate nutrients and are eaten by grazing herbivores, and the energy is transferred through a chain of organisms by consumption.
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 ]
In at least some cases, the export of carbon fixed in mangroves is important in coastal food webs. [53] Mangrove forests contribute significantly to coastal ecosystems by fostering complex and diverse food webs. The intricate root systems of mangroves create a habitat conducive to the proliferation of microorganisms, crustaceans, and small fish ...
The Borneo lowland rain forests is an ecoregion, within the tropical and subtropical moist broadleaf forests biome, of the large island of Borneo in Southeast Asia. [1] It supports approximately 15,000 plant species, 380 bird species and several mammal species.
Luzon is the largest island in the Philippines, and the Luzon rain forest is the most extensive rainforest ecoregion of the country. The ecoregion includes the lowlands of Luzon and neighboring islands below 1000 meters elevation. Very little of the original rainforest remains, and the status of this area is critical/endangered.

The Tropical Forest Research Station was founded in 1940 and became a center for ecosystem research. [1] It was designated as a UNESCO Biosphere Reserve in 1976 with the objective of understanding "the long-term dynamics of tropical forest ecosystems characterized by large-scale, infrequent disturbance, rapid processing of organic material, and high habitat and species diversity".
Within a food web, a food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level ...
