Plants obtain their energy from the sun. Other beings rely on eating to survive. Yet how does the energy flow inside ecosystems function and are there differences between ecosystems with many species in comparison to those with few species? Researchers have now examined these questions using a holistic approach by evaluating data gathered through a large-scale biodiversity experiment.... PHYS.ORG · 1 month
