Herbivores: Level 2 of the trophic chain consists of organisms that consume primary producers. Such species are often termed herbivores. Herbivores may be very small organisms such as zooplankton that graze on microscopic plants such as phytoplankton; however‚ herbivores also include many enormous mammals such as rhinoceri and elephants. If significant numbers of the herbivore trophic level are removed‚ plant growth may exceed the balance found in the previous natural environment. For example the

In a study conducted on the west coast of Vancouver Island by Markel & Shurn (2015)‚ they observed a classic tri-trophic cascade involving sea otters‚ sea urchins‚ and kelp. Their findings displayed a clear relationship between the presence of sea otters‚ with the abundance of sea urchins‚ and the resulting kelp forest depth and surface area. In the areas where sea otters were absent‚ sea urchins were found to be overabundant and the kelp forests were small and shallow. However‚ at locations with

Cascading Trophic Effects in Response to Apex Predator Removal Introduction The seemingly simple interaction between predator and prey can create effects that disseminate throughout an entire ecosystem. These interactions‚ or lack thereof‚ specifically result in trophic cascades. Cascading trophic effects typically occur from a change in the population density of apex predators. Due to the ever increasing impact of humans on nature‚ this field of ecological study is gaining more popularity as ecologists

Critically evaluate the consequences of anthropogenic disruption of trophic cascades in terrestrial ecosystems. Throughout the biological history of the earth various mass extinction events have occurred (2) in which worldwide biodiversity greatly declined. Currently‚ we are in the process of the sixth mass extinction (3) which unlike those before it‚ is characterised be the loss of large bodied species and more specifically the loss of apex consumers (4.5). Furthermore; current extinctions are

A trophic cascade is defined as ecological changes such as alterations in species abundance or composition‚ nutrient concentrations of plants‚ and the physical structure of the vegetation and environment. After wolves were eradicated from Yellow Stone National Park it caused a collapse in the tri-trophic cascade of predators‚ prey‚ and vegetation. They were reintroduced to restore the cascade that was present in the past to the park. The reintroduction of the wolves resulted in a major decline in
