Final answer:
Jingyi's environmental concerns in her fishery differ from those in natural bodies of water mainly in that she does not need to worry as much about natural predators, but must manage other issues like water quality, disease control, and nutrition.
The correct answer to her concerns is D. She doesn’t need to be concerned about natural predators
Step-by-step explanation:
Jingyi, who operates a fishery, would likely have environmental concerns that differ from those related to natural bodies of water. In particular, the correct answer to her concerns is D. She doesn’t need to be concerned about natural predators as much as someone managing a natural body of water would. Fisheries are controlled environments where factors like predator presence are managed, unlike in wild ecosystems where top predators play a critical role and their removal can endanger entire ecosystems. However, Jingyi must still be vigilant about issues such as water quality, disease, and ensuring proper nutrition, as these are crucial for the health of farmed fish.
Fisheries are also subject to the challenges of maintaining the biogeochemical cycles of substances like water, carbon, nitrogen, phosphorus, and sulfur, which are crucial for ecosystem functioning. Human activities such as overfishing can impact these cycles and have consequences for sustainability and ecosystem health. Moreover, Jingyi, like other producers, must be aware of health recommendations such as those from the EPA concerning the accumulation of heavy metals like mercury in seafood, which can impact both the environment and human health.
