Question and answer
Q: what can you conclude about the importance of a marine ecosystem to global food webs and the biosphere
A: Marine food webs play a key role in regulating these ecosystem services but there are important gaps in our knowledge and understanding of these functional roles and the way they might respond to environmental change. [ There is evidence that marine food webs are affected by both 'bottom-up' and 'top-down' processes. However, existing knowledge is much greater for lower trophic levels and
associated biophysical factors and it is therefore difficult to understand the role of these processes and how the effects of climate change will cascade through the food web and impact on ecosystem services. 'Top-down' and 'bottom-up' processes are also inherently scale-dependent. Scale-dependence is poorly understood which makes it difficult to quantify the large-scale impacts on ecosystem services of changes at small spatial scales (eg marine conservation zones); and vice versa. How functional diversity affects the way marine food webs regulate ecosystem services is unclear, however there is evidence that a loss of biodiversity can negatively impact on ecosystem functioning and services. ]

Toxicologists study the harmful effects of chemical, physical and biological agents on living organisms by detecting and examining the symptoms, mechanisms and treatments of poisoning (especially the poisoning of people).
