Final answer:
More information is needed to determine the number of plants available for hummingbirds after bee pollination. Bees are critical pollinators for numerous plant species, and their decline could impact certain plant populations and related industries, even though other animals might partially compensate for their role.
Step-by-step explanation:
To determine how many plants are left for the hummingbirds after bees pollinate 9780 plants, additional information would be needed. Specifically, one would require data on the total number of plants available, whether bees and hummingbirds pollinate the same plants, and if there is any overlap in plant species pollinated by both. Answer option 'c' I need more information to calculate, is thus the correct choice.
Bees are vital pollinators affecting many flowering plant species, including three quarters of food crops. Honeybees and wild bees are essential in ecosystems and agriculture for plant reproduction and fruit production. The decline in bee populations could have significant consequences not only for bee-dependent plant species but also for industries like the honey and fruit harvest trade. Nevertheless, some plants could still be pollinated by other animals if bees were not available, although often with reduced efficiency and potentially decreased fruit yield.
Comprehensive pollination research might provide insights into these interactions by tracking variables such as the number of butterfly visits per flower per day or the number of fruits produced per flower when access by specific pollinators is restricted. This data could help justify or refute the suggestion that a decline in a particular pollinator species is affecting plant populations.
