A coastal city is experiencing increased flooding due to rising sea levels. Engineers propose restoring local mangrove forests rather than building a concrete sea wall. Which statement best evaluates this solution based on the principle of biodiversity?

Restoring biodiversity has no impact on physical environmental factors like wave energy or soil erosion.

The mangrove forest is a better solution because it increases ecosystem complexity and provides secondary services like nurseries for fish.

The sea wall is the superior solution because it is anthropogenic and specifically designed to resist all environmental changes.

Mangroves are less effective because they release carbon dioxide during photosynthesis, contributing to further climate change.

Method B reduces the need for synthetic fertilizer because legumes house bacteria that perform nitrogen fixation.

Synthetic fertilizers are more anthropogenic, so they are more easily recycled by the decomposers in the soil.

Method B is less sustainable because legumes deplete the soil of carbon while they fix nitrogen.

Legumes directly absorb nitrogen gas through their leaves to produce glucose for the ecosystem.

Resilience will increase because the new vine adds to the total biomass of the producer level.

The carrying capacity for all forest animals will increase as the vines provide more cover.

The ecosystem will enter a state of genetic equilibrium because the vines prevent new mutations from occurring.

Resilience will decrease because the loss of oak trees reduces the variety of niches and food sources available.

The data suggests that the combustion of fossil fuels has increased the greenhouse effect by adding 'old' carbon back into the active cycle.

The correlation proves that natural volcanic activity is the sole driver of modern climate change.

The correlation is purely coincidental because the carbon cycle is not affected by human technological processes.

Increased temperatures cause plants to perform more photosynthesis, which is the primary cause of rising CO_2.

A positive feedback loop designed to maximize the fish population indefinitely.

Eliminating the niche of the fish to protect the water quality of the lake.

Changing the genotype of the fish to make them more resistant to being caught.

Mitigating human impact by ensuring the rate of use does not exceed the rate of reproduction.
