A loss of biodiversity is more subtle (37) an overall drop in absolute numbers of (38) or plants, but it’s still (39) a problem because the (40) species in an ecosystem, the more the system (41) on each one of them, and if disease or some other (42) wipes out a species, its function could go unfilled. In the (43) of bees, that (44) is to pollinate plants, both wild and crop plants. And (45) the authors of the study show, there’s been a (46) decline in plants that were once pollinated (47) the disappearing bees. Indeed, it isn’t clear (48) came first, the plant decline or the decline in bees. It’s also not clear (49) any crops are in trouble, only that there’s a potential for it if this trend continues. It’s also not clear (50) it’s happening.
