I think it is C not 100% sure though
Answer:
Option C, making ATP to power cell activities
Explanation:
In cellular respiration, the energy stored in food is converted to readily available energy form i.e ATP (Adenosine Triphosphate) molecule. During cell respiration, the cell breakdown the glucose (carbohydrate) molecule into carbon dioxide (CO2), H2Oand ATP (energy molecule).
ATP being an energy molecule act as a source of energy for all metabolic processes. Along with ATP , higher level energy molecules like NADH is also produced.
Hence, option C is correct

Help control weeds and insect pests.
Explanation:
Insect are the largest group of organisms on Earth. They belong to the phylum arthropoda and class insecta. They have hard exoskeleton, antenna, they have three pairs of legs and their body is divided into head, thorax and abdomen.
Insects are biological resources in that they help control weeds and insects pest.
The insects are use as weed control in that they feed on the weeds i.e they use the weeds as food there by absorbing the nutrients for weeds development, which lead to their inability to survival. Some canivorous insects feed on insects pest i.e use they as food, thereby reducing their harmful effects in the ecosystem.
