What autotrophs are found in the food web?

In this particular food web, the following autotrophs are found:

- Grass: Grass serves as the primary producer in this ecosystem, capturing energy directly from the sun through the process of photosynthesis and converting it into organic matter.

- Plants: Plants, including shrubs and trees, are photosynthetic autotrophs that convert sunlight into chemical energy stored within their tissues.

- Phytoplankton: Although not specifically mentioned, if the food web includes an aquatic environment, phytoplankton (microscopic algae) would be present as autotrophs, forming the foundation of the food web.
