is this a joke? yes, there is obviously a loss of energy and material as waste when go a step, just like in real ecological networks where one animal eating another does not absorb everything its body has to offer for nutrients

It's not a joke, because people continue to eat inefficiently higher up on the food chain.

We aren't so starved so as to have to prioritize eating efficiently, people will eagerly prioritize aspects of taste and eat inefficiently, and it's great that they can do that - it would be horrific and a symptom of unacceptable overpopulation if people couldn't afford to eat "inefficiently" and would have to resort at eating whatever as long as it has sufficient nutrients.
