Answer:
the reason for which something exists or is done, made, used.
Gross primary productivity (GPP) is the rate at which - E: producers convert radiant energy into chemical energy
Gross primary productivity, or GPP, is the rate at which light energy or radiant energy is used to form and store chemical energy in sugar molecules during photosynthesis.
- Producers use stored chemical energy for metabolism and cellular respiration for growth and development.
- amount of living organic material is supported by a particular ecosystem.
- the energy produced per unit area over a given time span
Thus, Gross primary productivity (GPP) is the rate at which - E: producers convert radiant energy into chemical energy

The correct option is D.
When it comes to movement of particles in an out of cells, there are two basic types of transportation, these are passive and active transportation. The passive transportation of particles does not require the use of energy while the active transport system requires the use of energy in the form of ATP. From the diagram given in the question, it can be seen that energy is involved in the process. Energy is mainly needed to move the particles against the concentration gradient since the inside of the cell is highly concentrated while the outside has low concentration. <span />
Answer: Most viruses can use host machinery to produce more of themselves
Explanation:
Since viruses carry out no metabolism themselves, they rely solely on the living cells of the host (organism they infect) to replicate and spread from cell to cell.
Thus, viruses do not kill the cells they infect since they need them, and use them to replicate more offsprings
