A top-down cascade is caused by a change in some factor(s) affecting the survival or productivity of the upper trophic level(s) of a food chain or web, and manifests as an inverse changes in abundance or biomass between adjacent pairs of trophic levels (Carpenter et al. 1985; Pace et al. 1999).Hence, …James Estes and colleagues discovered that the kelp forest ecosystems of the North Pacific are regulated by the presence or absence of sea otters, which feed on sea urchins that consume kelp. These direct and indirect effects of starfish, sea otters and other so-called keystone species describe a phenomenon known as a trophic cascade.Defining Trophic Cascades. Therefore, we propose the following definition (see Box 2 for related terms): ' Trophic cascades are indirect species interactions that originate with predators and spread downward through food webs'. This definition is consistent with Paine's original conception of nested sets of species interactions [5].The positive, top-down indirect effect of wolves on beavers goes through many trophic levels. Beavers are "engineer species",which create habitat for many others; by promoting certain plants, they have a positive"bottom-up" effect on the ecosystem. So, the thistrophic cascade, triggered by the restoration of wolves, flows both ways.Several landslides and floods were triggered by unprecedented, incessant heavy monsoon rainfall from 4 August 2019 to 8 August 2019, along the northern slopes, at Kavalappara, in the Malappuram ...https:// Directions: While watching the video clip, answer the questions below using complete sentences.

A lower ...The Casini et al. study, however, has a stronger case for a trophic cascade by having quantitative data for the entire food web before and after the addition of cod in this large marine ecosystem.

B Wolves leaving the park may prey on livestock in grazing land outside the park. C Wolves are extremely fast breeders and may become an invasive species if they get outside the park. Complex food webs support diverse ecosystems. If Trophic cascades occur when predators reduce the abundance or change the activity of their prey, thereby allowing species in the next trophic level to increase in number. These indirect effects by the predator can trickle down (or cascade) to many lower levels of the food chain. Cascades are considered more common in marine ecosystems [9,10]...
