Answer:
<em>The nutrient cycle </em><em>is nature's recycling system. All forms of recycling have feedback loops that use energy in the process of putting material resources back into use. </em><em>Recycling</em><em> in ecology is regulated to a large extent during the process of decomposition.</em><em> Ecosystems employ biodiversity</em><em> in the food webs that recycle natural materials, such as mineral nutrients, which includes water. </em><em>Recycling in natural systems</em><em> is one of the many ecosystem services that sustain and contribute to the </em><em>well-being</em><em> of human societies.</em>

The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.
Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
