Bio.2.1 Analyze the interdependence of living organisms within their environments.

Bio.2.1.1 Analyze the flow of energy and the cycling of matter (such as water, carbon, nitrogen and oxygen) through ecosystems relating the significance of each to maintaining the health and sustainability of an ecosystem.

*Living systems require a continuous input of energy to maintain organization. The input of radiant energy which is converted to chemical energy allows organisms to carry out life processes.

Bio.2.1.3 Explain various ways organisms interact with each other (including predation, competition, parasitism, mutualism) and withther environments resulting in stability within the ecosystem.

*Explain patterns in predator/prey and competition relationships and how These patterns help maintain stability within an ecosystem with a focus on population dynamics.

Bio.2.1.4 Explain how disease can disrupt ecosystem balance. (Avian Flu, Enteritis, Kinky Back (spondylolisthesis), Dermatitis, Delmarva 16, Georgia 08, Air Sac, Yolk retention.

Bio. 4.2 Analyze the relationships between biochemical processes and energy use in the cell.

Bio 4.2.2 Explain ways that organisms use released energy for maintaining homeostasis.

*Conclude that energy production by organisms is vital for maintaining homeostasis and that maintenance of homeostasis is necessary for life. Examples: Active transport of needed molecules or to rid the cells of toxins; movement to avoid danger or to find food, water, and or mates; synthesizing needed molecules.

EEn.2.8 Evaluate human behaviors in terms of how likely they are to ensure the ability to live sustainably on Earth

EEn2.82 Critique the advantages and disadvantages of traditional agriculture techniques and compare with the sustainable agriculture/aquaculture techniques. Include the economics and environmental impacts in this comparison. Judge potential impact of sustainable techniques on environmental quality (include magnitude, duration, frequency).

PSc.3.1.1 Compare conduction, convection, and radiation as methods of energy transfer. (Poultry houses use radiant heaters, windows, and light bulbs that heat the environment.)

PSc3.1.4 Determine the component simple machines present in complex machines – categorize a wedge and a screw as a variation of an inclined plane, a pulley and wheel & axle as variations of a lever. (The auger system of transferring feed in the 600 feet of the house is a screw, pulleys and levers are used throughout the houses to raise, lower, and move machinery.)

Phy1.2.2 Specifically applied to feed lines

Analyze systems of forces involving

*Objects at rest (on a surface or suspended)

*Objects pulled or pushed along a horizontal surface by an applied force that is either parallel to the surface or applied at an angle,

*Objects sliding or rolling down an inclined plane

Distinguish forces on objects based on interactions including contact and forces at a distance (normal force, weight, friction tension, applied force)
