Question

1. in the clip, between minutes 3-5, which 2 ideas will help make fish farming more efficient? (choose the 2 choices that fit best.) (2 points) building vertical farming units polluting the water growing microscopic fungi on industrial waste to be used as fish food halting the building of aquaponics

Explanation:

To determine the ideas that help make fish farming more efficient, we analyze each option:

• "Building vertical farming units": Vertical farming can optimize space usage, which is beneficial for fish farming (e.g., in aquaponics or integrated systems) to increase efficiency.
• "Polluting the water": Polluting water harms fish and the ecosystem, so it does not help efficiency.
• "Growing microscopic fungi on industrial waste to be used as fish food": This is a sustainable way to produce fish food, reducing costs and environmental impact, thus increasing efficiency.
• "Halting the building of aquaponics": Aquaponics is a system that combines fish farming with plant cultivation for efficiency; halting its construction would not help efficiency.

Answer:

• Building vertical farming units
• Growing microscopic fungi on industrial waste to be used as fish food
