What is the process by which the chemical reactants for the light dependent reactions of the photosynthesis enter a chloroplast?

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
