"Flow of energy is unidirectional." Name the first two components of the environment involved in this flow of energy from the sun.

(N/A) The flow of energy in an ecosystem begins with the sun. The first two components involved in this process are:
$1$. Producers (Autotrophs): These are green plants that capture solar energy and convert it into chemical energy through the process of photosynthesis.
$2$. Primary Consumers (Herbivores): These organisms obtain energy by feeding directly on the producers.
