Which of the following is NOT an example of energy transformations in an ecosystem?

• A. Photosynthesis converting solar energy into chemical energy
• B. Herbivores digesting plant material to obtain energy
• C. Cellular respiration converting chemical energy into ATP
• D. Water evaporating from a pond due to sunlight

Answer: (D)

Verified step by step guidance

1. Step 1: Begin by understanding the concept of energy transformations in an ecosystem. Energy transformations involve the conversion of one form of energy into another, which is essential for biological processes. Examples include photosynthesis, digestion, and cellular respiration.
2. Step 2: Analyze the first option: 'Photosynthesis converting solar energy into chemical energy.' Photosynthesis is a key energy transformation where plants use sunlight to synthesize glucose, storing energy in chemical bonds. This is a valid example of energy transformation.
3. Step 3: Examine the second option: 'Herbivores digesting plant material to obtain energy.' Digestion involves breaking down food molecules to release chemical energy, which is then used by the organism. This is another valid example of energy transformation.
4. Step 4: Evaluate the third option: 'Cellular respiration converting chemical energy into ATP.' Cellular respiration is a process where organisms convert the chemical energy stored in glucose into ATP, the energy currency of cells. This is also a valid example of energy transformation.
5. Step 5: Consider the fourth option: 'Water evaporating from a pond due to sunlight.' Evaporation is a physical process where water changes from liquid to gas due to heat energy from sunlight. This does not involve the conversion of energy into a form usable by living organisms, so it is NOT an example of energy transformation in an ecosystem.
