Pioneer species in plant succession arrive at cleared areas to germinate. however, when they grow, the shade they produce makes it impossible for their own seeds to again germinate there because of their shade intolerance. instead other more shade-tolerant species come in, grow, and force out the pioneer species. how do pioneer species ever get their seeds germinate if the parent plants always modify the habitat enough to make it inhospitable?

Which of the following would be the best hypothesis for this experiment? a) use of the ginko biloba extract improves clinical outcomes when administered to patients with t2d. b) ginko biloba improves clinical outcomes of diabetes patients when combined with metformin. c) diabetes in patients is worsened when ginko biloba is taken in conjunction with metformin. d)the use of ginko biloba to treat t2d in combination with metformin lowers the cost of t2d treatment. ginko biloba shows benefits against t2d when combined with plant extracts as compared to other treatments.
