Change over time. I believe this is a multiple choice question, but you have not provided the options.
The patient probably has diabetes insipidus.
Diabetes insipidus is a disease that caused by decreases in antidiuretic hormone that produced by the hypothalamus. The antidiuretic hormone will be secreted when the body lacks water. It will decrease the urine production(antidiuretic) and increase thirst to replenish the water.
Continous <span>deficiency of antidiuretic hormone will cause the person to continuously create urine, make it diluted and the osmolarity becomes decreased. It will also cause continuous thirst.</span>
The answer is option B "a decrease in the number of consumers." Producers are plants. When making roads, and parking lots it causes deforestation which is the process of taking out a lot of plants which is a huge decrease in producers for that ecosystem. Also would take out a lot of habitats for animals which would cause death unless the animals can adapt to their new environment, or move to a new ecosystem. Which means either one could be correct.
Hope this helps!
