Question

what is the major biological process that transports nutrients from the soil and water (salinity, weathering) provision of the worlds ecosystem into plants (roots, living portion)?

Explanation:

Plants absorb nutrients from water and soil mainly through the process of active transport and diffusion. However, the main biological process that transports nutrients from the soil - water solution into the living portion of the plant is called active uptake. Among the given options, phloem transport is mainly for the movement of photosynthetic products (sugars) within the plant, not for nutrient uptake from soil - water. Root pressure is related to the upward movement of water in plants. Transpiration is the loss of water vapor from plants. Active uptake is the process by which plants selectively take up ions and other nutrients from the soil solution against their concentration gradient, using energy. But if we assume the closest option among the given ones, phloem transport is incorrect as it's for organic compound movement, root pressure and transpiration are not nutrient - uptake processes from soil - water to living plant parts in the main sense. So, if we consider the options provided and the context of nutrient movement from soil - water to plant living parts, the best answer is active uptake which is not in the options, but if we have to choose from the given ones, phloem transport has some relation to internal plant transport and is the most relevant compared to the others which are more off - topic.

Answer:

C. phloem transport
