(1)

C

Explanation:

The illustration shows carbon dioxide moving from the atmosphere to the plant. This can only occur through the process of photosynthesis because the process utilizes carbon dioxide and sunlight energy to make glucose (hence storing the carbon in the plant). Plants are major carbon sinks and play a significant role in mitigating global warming by reducing the accumulation of carbon dioxide as a greenhouse gas in the atmosphere

(2)

C

Explanation:

Overfishing reduces marine populations because the activity reduces a species' population too drastically to very low levels such as the individuals left are not adequate enough to repopulate the species leading to a spiraling effect of reduced population size and growth leading towards extinction. It is important that Ben ensure that fishing for the shrimp does not reduce the population below this critical point where re-population of the shrimp may become impossible.

(3)

A

Explanation:

Logging will enure the current generation benefits from the current natural resources, in this case, the tree. Planting of at least a tree for every downed tree ensures that the young tree will grow and mature and will be utilized by upcoming generations. This ensures a sustainable cycle with each generation benefiting from the natural resources (trees). The other choices are not as sustainable.
