Definition Trophic level is the relative position of an entity in the food chain. It forms the feeding positions in a food web or chain. All food webs and chains have at least two or three trophic levels. An …

The next level is occupied by the next trophic level, i.e., the primary consumers and so on. All the calculations for construction of these types of ecological pyramids must take into account all the …

Trophic level refers to the sequential stages in a food chain, starting with producers at the bottom, followed by primary, secondary and tertiary consumers. Every level in a food chain is known as a …

For instance, in the grazing food chain, there is a distinct transfer of energy flow between different trophic levels. Energy for this type of food chain is from the dead and decomposed matter known as …

Thus, the energy flow is unidirectional in nature. Moreover, in a food chain, the energy flow follows the 10 percent law. According to this law, only 10 percent of energy is transferred from one trophic level …

Biomagnification Definition “Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, …

Biomagnification The process of a buildup of certain chemical substances or toxins at the higher trophic levels of a food chain is termed Biomagnification. This is also referred to as biological magnification. …

Trophic level is the specific place that a living organism occupies in a food chain. In a biomass pyramid, producers (1 st trophic level) are at the base, followed by herbivores (primary consumers) and then …

The three vital aspects of an ecological niche are – physical level, function role and its position in the environmental gradient. Based on this, ecological niche can be classified into three types – Habitat or …

E.g. seven species of millipedes reside in the same general habitat of the forest floor of a maple oak forest, and all are decomposers, i.e. occupy the same trophic level but predominate in their specific …
