Exploring trophic cascades answer key.
Trophic cascade hypotheses for biological communities, linking predation by upper trophic levels to major features of ecological structure and dynamics at lower trophic levels, are widely subscribed and may influence conservation policy. Few such hypotheses have been evaluated for temporal or spatial generality. Previous studies of sea otter (Enhydra lutris) predation along the outer coast of ...
Example Experimental Design: This is an example of how an experiment could be designed. Each circle represents one cup. Here, there are three treatments, each with four replicates. Algae concentration should be measured before the addition of Daphnia at the start, and again after one week.To enable screen reader support, press Ctrl+Alt+Z To learn about keyboard shortcuts, press Ctrl+slashVerified answer. engineering. The figure shows a gate hinged at its bottom and held by a simple support at its top. The gate separates two fluids. Determine the net force on the gate due to the fluid on each side. Then compute the force on the hinge and on the support. Verified answer. Trophic cascade, an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain. A trophic cascade often results in dramatic changes in ecosystem structure and nutrient cycling.

In many streams, for example, if only algae are present, they grow until their biomass becomes nutrient-limited, producing a “green” surface (Fig. 10.8).

What is a "trophic cascade"? Trophic cascade is when the species that make up the different levels of the ecosystem balance out each other after one is changed by a reduction in population.
THE TROPHIC CASCADE HYPOTHESIS In 1979, Paine combined his own results with those of others, including Estes and Palmisano, to propose the idea of trophic cascades, in which direct and indirect effects from a species at or near the top of the food chain propagate down and regulate the species and population sizes in the rest of the community.
