Sustainability is the ability to sustain production of goods today without impairing our ability to produce goods in the future. Managing resources for their continued use, not just conservation is the ultimate goal of sustainability. Aquaponics is a relatively new branch of food production which utilizes both plant production and fish production in one. In essence, it combines aquaculture and hydroponics (raising plants without soil) in which fish and plants are grown together in one integrated system. The waste from fish provides an organic food source (fertilizer) for the plants and the plants naturally filter the water for the fish. Aquaponics is becoming a popular way to grow both fish and plants because of the advantages it provides to society. What would NOT be an advantage of aquaponics?

A) Evaporative losses are significantly reduced, so water is conserved.

B) Since the fish supply the nutrients needed for plant growth, costly fertilizers are not needed.

C) Vegetables can grow in a climate controlled environment, preventing farming losses from a bad season.

D) Aquaponic systems require electricity to run the system which can be difficult in developing countries.

Answer: Aquaponic systems require electricity to run the system which can be difficult in developing countries.

Answer:aquaponics would create further divide between the rich and poor as electricity is needed to run the system. Underdeveloped countries would essentially be socially excluded from this system

An example of natural selection is the peppered moth found in Europe. There are two color forms of this moth, shown in the diagram. Form X was more common before the industrial revolution covered the trees with smoke and dust. Form Y is more common after the industrial revolution. Which statement explains why these two color forms exist at the same time? *


Some organisms inherit traits enabling them to adapt better to the environment.
Some organisms acquire traits during their lifetimes that they pass to our offspring.
Some organisms do not reproduce as many offspring during their lifetimes.
Some organisms die before they reproduce offspring.

In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar. This sugar can then be consumed by other organisms to be used as building blocks for other molecules, such as proteins and fats, or it can be transformed into other forms of energy, such as kinetic energy, when the organism moves. Which of the following statements is supported by the above information? A. Energy can change forms, but only one kind of matter exists. B. Matter can change forms, but only one kind of energy exists. C. Matter and energy can change forms and locations in ecosystems. D. Matter and energy must always remain in the same form and location.
