Question

which of the following hypotheses did the biologists most likely make based on their observation? choose 1 answer: a if hawaiian honeycreepers go extinct, then plant pollination rates will decrease. b if hawaiian honeycreepers go extinct, then seed density near parent plants will increase. c if hawaiian honeycreepers go extinct, then nutrient levels in soil will decrease. d if hawaiian honeycreepers go extinct, then plants will experience more insect damage.

Explanation:

Hawaiian honeycreepers are likely pollinators for plants. If they go extinct, the pollination they facilitate would reduce, leading to decreased pollination rates. Option B: Seed density near parent plants is more related to seed dispersal (if honeycreepers disperse seeds, extinction would likely decrease seed density, not increase). Option C: Soil nutrient levels are more related to decomposers or nutrient - cycling organisms, not directly to honeycreepers. Option D: Insect damage to plants is not directly linked to honeycreeper extinction; honeycreepers don't primarily affect insect - plant damage relationships. So the most logical hypothesis is A.

Answer:

A. If Hawaiian honeycreepers go extinct, then plant pollination rates will decrease.
