Understanding Food Chains and Energy Conservation in Ecosystems

Explore the role of spiders within a food chain involving plants, aphids, and sparrows. Are they producers, primary consumers, competitors, or secondary consumers? This guide discusses these ecological roles, along with the principles of energy conservation, explained through key formulas such as gravitational potential energy (GPE) and kinetic energy (KE). Delve into the relationships within ecosystems and how energy is transformed, ensuring a comprehensive understanding of biological interactions and energy formulas.

  2. Conservation of Energy October 19, 2010

  3. Regular Energy Formulas • GPE= mgh • KE = ½ mv2 • Uspring= ½ kx2 • The potential energy of a spring

  4. Conservation of Energy Ei = Ef KEi + PEi = KEf + PEf ½ mvi2 + mgh = ½ mvf2 + mgh
