What is the primary source of energy converted by producers in an ecosystem?
A
Heat from the Earth's core
B
Kinetic energy from wind
C
Sunlight
D
Chemical energy from soil
Verified step by step guidance1
Identify the role of producers in an ecosystem. Producers, such as plants, algae, and some bacteria, are organisms that can produce their own food through the process of photosynthesis.
Understand the process of photosynthesis. Photosynthesis is the process by which producers convert light energy into chemical energy stored in glucose molecules.
Recognize the source of energy for photosynthesis. The primary source of energy for photosynthesis is sunlight, which is absorbed by chlorophyll in the producers.
Differentiate between the types of energy sources listed. Heat from the Earth's core and kinetic energy from wind are not used by producers for photosynthesis. Chemical energy from soil is not a direct energy source for producers.
Conclude that sunlight is the primary source of energy converted by producers in an ecosystem, as it provides the necessary energy for photosynthesis to occur.
