2003 study, alexander and schrag tested the effect of plant litter on seedling emergence in a grassland setting. the test site was a mesic grassland in a dry midlatitude climate in the united states. the researchers found that in these environmental conditions the presence of plant litter had a positive effect on seedling emergence. seedling emergence is when a seedling sprouts above ground and begins photosynthesis. question: which choice most effectively uses information from the given sentences to present the studys findings to an audience already familiar with the concept of seedling emergence? a the findings of alexander and schrags study were published in 2003. b in a 2003 study by alexander and schrag, plant litter was found to have a positive effect on seedling emergence, which is when a seedling sprouts and begins photosynthesis. c the effect of plant litter, which includes dead leaves and other plant matter, on seedling emergence has been the subject of scientific study. d alexander and schrag found that in a mesic grassland and a dry midlatitude climate the presence of plant litter had a positive effect on seedling emergence.

Explanation:

We need to present the study's findings to an audience familiar with seedling emergence. Option B clearly states that in the 2003 study by Alexander and Schrag, plant litter had a positive effect on seedling emergence and also defines seedling emergence. Option A just mentions publication year. Option C is too general about the subject of study. Option D does not define seedling emergence for the audience.

Answer:

B. In a 2003 study by Alexander and Schrag, plant litter was found to have a positive effect on seedling emergence, which is when a seedling sprouts and begins photosynthesis.
