Am I missing something or your statement sounds like livestock do not require land to grow their food? Example from ten percent law [0]: > Sun releases 1000 J

Am I missing something or your statement sounds like livestock do not require land to grow their food? Example from ten percent law [0]: > Sun releases 1000 J of energy, then plants take only 100 J of energy from sunlight; thereafter, a deer would take 10 J from the plant. A wolf eating the deer would only take 1 J. A human eating the wolf would take 0.1J, etc. We can go directly from plants to people instead of using land, energy and resources to grow plants to feed animals for human consumption with 10% efficiency.
