How do the roots of most plants obtain food for survival? a)they store food within them. b)the phloem tissue carries food to the roots. c)they survive by absorbing water from the soil. d)they make their own food, like the rest of the plant.

B)The phloem tissue carries food to the roots.

Explanation:

As you may already know, plants produce their own food through photosynthesis. However, these foods are produced in the leaves, but need to be distributed throughout the plants, including must reach the roots. Who distributes the products produced during the photosynthesis is Floema.

Phloem is an important tissue related to the conduction of elaborate sap (produced in photosynthesis) in the body of the plant. This means that it is through this tissue that substances such as water, sucrose, amino acids, nucleic acids, vitamins and inorganic ions are transported to all parts of the plant, including the roots.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
