Algae contributes to a lot of the energy and nutrients at the base of the food chain along with terrestrial litter-fall that enters the stream or river. [34] Production of organic compounds like carbon is what gets transferred up the food chain. Primary producers are consumed by herbivorous invertebrates that act as the primary consumers ...
Moist broadleaf forest in Mudumalai National Park Congolian rainforest dominated by Gilbertiodendron dewevrei, near Isiro. TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn. TSMF are characterized by low variability in annual temperature and high ...
A diagram that sets out the intricate network of intersecting and overlapping food chains for an ecosystem is called its food web. [6] Decomposers are often left off food webs, but if included, they mark the end of a food chain. [6] Thus food chains start with primary producers and end with decay and decomposers.
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.

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.
This reliance underscores the critical role of native plants in supporting ecological food chains. The distinction between generalists and specialists is not limited to animals. For example, some plants require a narrow range of temperatures, soil conditions and precipitation to survive while others can tolerate a broader range of conditions.
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...
Most of the interior of the Amazon basin is covered by rainforest. [6] The dense tropical Amazon rainforest is the largest tropical rainforest in the world. [2] It covers between 5,500,000 and 6,200,000 square kilometres (2,100,000 and 2,400,000 sq mi) of the 6,700,000 to 6,900,000 square kilometres (2,600,000 to 2,700,000 sq mi) Amazon biome.
