Cellular Respiration

Explanation:

Chemical energy in plants is typically stored within the bonds of glucose molecules. These are broken down during respiration, in a process that generates the energy molecules, ATP. Glucose is converted to pyruvate in the cytoplasm; then,  in the mitochondria, this process uses O2 for ATP generation in the Citric acid cycle, along with oxidative phosphorylation. Carbon dioxide is produced along with water and molecules of ATP.

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
