Relationship between science and technology. The relationship between a predator and its preys food source is often described as. Trophic cascades are powerful indirect interactions that can control entire ecosystems occurring when a trophic level in a food web is suppressed.

What types of factors should be investigated. Be sure to incorporate information that youve learned in this lesson outside research and your lab work including-a reference and explanation of trophic cascade 5 points -research on other predator-prey relationships5 points -identification of the independent variable for all 3 experiments. I predators suppress herbivores and allow plants to thrive and ii apex predators suppress smaller mesopredators releasing herbivores to suppress plants 46 p3.

A symbiotic relationship that results in one species benefiting and the other. Jara and Moreno 1984. It remains unclear whether the urchin response was triggered directly via a reduction in urchin mortality or indirectly via a shift in urchin distribution into areas previously occupied by the predatory sea stars.

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. Top-down Trophic Cascade - Top-down means the effect of a consumer eg zooplankton on a resource eg phytoplankton.
