Producers Green plants - they make glucose during photosynthesis. Primary consumers Usually eat plant material - they are herbivores. For example rabbits, caterpillars, cows and sheep. Secondary ...

Energy flow diagrams often depict secondary production as the flow leaving one trophic level and entering (being ingested by) the next. Many ecologists, however, have demonstrated that secondary ...

Researchers explore the relationship between diet, blood glucose levels, and cancer incidence across vertebrate species.

Trophic cascades are powerful indirect interactions that can control entire ecosystems. Trophic cascades occur when predators limit the density and/or behavior of their prey and thereby enhance ...

While the oceans are now safe from the Megatooth, which went extinct an estimated 3.5 million years ago, Otodus megalodon has been revealed by new research to have occupied a higher position on the ...

Trophic levels correspond to the positions organisms occupy in a food chain based on their source of energy and nutrients. Essentially, they define the relationships between predators and prey in an ...

Remember, food chains do not show the number of organisms at each trophic level. Pyramids of number are not always perfect pyramids because of large organisms at the bottom and small ones at the top.
