The answers are "water and mineral ions" and "amino acids and sucrose" respectively.
For the xylem, it usually transports water and mineral ions that are absorbed from the root hair cells up to the leaves, where photosynthesis take place. Water is one of the necessary substance for photosynthesis to take place, while different mineral ions can help the plant by for example Magnesium ions can help produce chloroplast.
While phloem transports amino acid and sucrose from the location of production (eg. Leaves by photosynthesis) to the place where it is used or stored. Plant needs these substances to generate energy for activities such as growth by for example cellular respiration. This process is called translocation.
Both of these tubes help transport substances in the plant, in order to keep the plant alive.

Most density independent limiting factors are abiotic (nonliving). So, examples could be temperature, flood, pollution, earthquakes, etc. In your case, the answer would be C. The eruption of a volcano.
Answer A is wrong because that is a description of competition between organisms, which is a biotic factor.
Answer B is wrong because those are both biotic and density dependent factors.
Answer D is wrong because disease is potentially biotic, but primarily because parasitism is mentioned, which is interaction between two organisms. One benefitting, and one being "hurt" in some way.
Answer:
The equation represents a biological process that is Photosynthesis. This process is done by plant cell in their chloroplast.
Expanation:
Plants contain Chlorophyll Pigment that helps in the process of photosynthesis( a biological process through which plants can produce their own food with the help of sun light, Carbon dioxide and water and form glucose and oxygen).
This process takes place in chloroplast which contain double membrane with many folds. The double membrane encloses a structure called thylakoid that contain pigment chlorophyll. The function of chloroplast is to capture light that is required in the process of photosynthesis.
