The ecosystem will become unstable because predators will have fewer prey, the birds will have fewer nesting sites, and the area downriver will become vulnerable to flooding without the burrows to aerate the soil and provide drainage for monsoon rains.

The ecosystem will become more stable because the pika will be replaced by other species of small mammals that can fill the niche, bird species will adapt to nesting aboveground, and the soils will become compacted without the burrows.

The ecosystem will become unstable because the predators will migrate to nearby ecosystems, the birds will nest in nearby trees, and the soil will be aerated by other small mammals.

The ecosystem will become more stable because the pika will no longer be there to eat the grasses, the birds will migrate to other ecosystems during the nesting season, and the sims will be able to absorb more of the monsoon rains without the pika burrows.

Less atmospheric carbon dioxide would be available to phytoplankton

dissolved carbon dioxide gas int he ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas.

Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean

Less carbon dioxide would be dissolved in the ocean because increasing atmospheric temperatures would cause ocean temperatures to increase

Water evaporated faster on the side of the plant having full light.

Light sensors in the grass tips stimulated a hormone in the shoot system.

The xylem in the root system absorbed more nutrients from the shaded side.

The side facing the light has a greater chance of absorbing carbon dioxide from the atmosphere.
