Sure you can have plants which manage a 1% photosynthesis-to-carbon-fixation rate. Normal temperate crops have about 0.6%. But humans will not be 100% effective in eating that biomass. The average large mammal has a 3% efficiency in utilizing food - herbivores are worse because they need to spend energy to digest their energy-sparse fare.
