Answer» Right choice is (c) SERIOUS threat to the safety of the ecosystem The best explanation: An ecosystem consists of biotic and abiotic components that interact within a system. If there is a decrease in the number of bird species, the prey (FOOD that birds eat) and PREDATOR (ANIMALS eating those specific birds) both will be affected causing serious harm to the safety of the ecosystem.
