Question

ground—resources that some forest birds would typically eat and disperse. this observation leads the biologists to make a hypothesis about the effects of forest bird extinctions. which of the following hypotheses did the biologists most likely make based on their observation? choose 1 answer: a if guam forest birds go extinct, then seed density near parent plants will increase. b if guam forest birds go extinct, then nutrient levels in soil will decrease. c if guam forest birds go extinct, then plants will experience more insect damage. d if guam forest birds go extinct, then plant pollination rates will decrease.

Explanation:

The observation is about forest birds eating and dispersing seeds (resources). If birds go extinct, they can't disperse seeds, so seeds would stay near parent plants, increasing seed density there. Option A relates to seed density (from seed dispersal), while B (soil nutrients), C (insect damage), and D (pollination) are not directly tied to seed dispersal as per the observation.

Answer:

A. If Guam forest birds go extinct, then seed density near parent plants will increase.
