Concept explainers

Energy Flow

Energy flow is the continuous and directional flow of energy through living beings within an ecosystem. All living beings can be segregated into producers and consumers. These producers and consumers can be further divided in a food chain. The term ‘trophic level’ is assigned to each level of the food chain.

Question

Draw a food chain showing the relationships between these organisms, indicating the direction of the flow of energy.

We have seen that energy is essential for life on earth. All organisms need energy to maintain their cellular processes. There are two basic ways of generating energy de novo, at the base of food webs. Describe the two primary ways that autotrophic organisms generate energy, including the original source of energy and the primary organisms that carry out each process.
