Concept Explanation A. Unidirectional flow of energy 1. Energy flows from sun to producers to consumers B. First Law of Thermodynamics 2. Energy is conserved in a system C. Second Law of Thermodynamics 3. Systems tend to increase in entropy D. Detritus Food Chain 4. Begins with dead organic matter

Options

  1. AA - 1, B - 2, C - 3, D - 4
  2. BA - 4, B - 1, C - 2, D - 3
  3. CA - 3, B - 4, C - 1, D - 2
  4. DA - 2, B - 3, C - 4, D - 1

Correct answer

A. A - 1, B - 2, C - 3, D - 4

Step-by-step solution

Unidirectional flow of energy (A) refers to the energy flow from the sun to producers to consumers (1). The First Law of Thermodynamics (B) states that energy is conserved in a system (2). The Second Law of Thermodynamics (C) indicates that systems tend to increase in entropy (3). The Detritus Food Chain (D) begins with dead organic matter (4).
