Ok so I just looked this up so please don’t come at me if it’s wrong,

“Generally, no. Even in the open ocean (pelagic environments) you have phytoplankton on the bottom rung. What are phytoplankton? But there are certainly examples of non plant based ecosystems… they're just less common.”

I’m so sorry if this doesn’t help

Answer:No

Explanation: Because without plants, animals would have no oxygen to breathe and would die. People also depend on plants for food. All animals eat either plants or plant-eating animals. Without plants there would be no food at all.
