Benchmark 15-I

Artificial ecosystems are human-made complexes that replicate some aspects of the natural environment.

Benchmark 15-J

The development of refrigeration, freezing, dehydration, preservation, and irradiation provide long-term storage of food and reduce the health risks caused by tainted food.

Benchmark 15-K

Agriculture includes a combination of businesses that use a wide array of products and systems to produce, process, and distribute food, fiber, fuel, chemical, and other useful products.

Benchmark 15-L

Biotechnology has applications in such areas as agriculture, pharmaceuticals, food and beverages, medicine, energy, the environment, and genetic engineering.

Benchmark 15-M

Conservation is the process of controlling soil erosion, reducing sediment in waterways, conserving water, and improving water quality.

Benchmark 15-N

The engineering design and management of agricultural systems require knowledge of artificial ecosystems and the effects of technological development on flora and fauna.
