Yes.
To get a steak you have to spend a lot of energy on growing plants as food for the animal that will become the steak. And animals aren't that good at turning plants into meat, so you have to feed them a lot more than they produce.
If you grow plants to feed to people directly instead, bypassing the animal, the same amount of plants will feed a lot more people than the animal did.
It is an inefficient way of obtaining the energy that plants originally had because as the food chain progresses the energy obtained by each level decreases. As humans, we are at the top of the food chain. Therefore we obtain the least amount of energy.

A high amount of energy lost as heat is a clear indicator that the transfer of electrical energy to the lamp is inefficient. This can typically be observed by feeling the lamp and the surrounding area for excess heat.
Energy inefficiency can be caused by factors such as poor insulation, outdated technology, lack of maintenance, and inefficient equipment. These can lead to energy losses in the form of heat, friction, or other forms of waste. Identifying and addressing these factors can help improve energy efficiency.
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
Energy-deficit regions are typically found in countries or areas with limited natural resources, inefficient energy infrastructure, or high energy demand. Developing countries in Africa, Asia, and parts of Latin America often face energy deficits due to inadequate investment in energy production and distribution systems. These regions may struggle to meet the energy needs of their populations, leading to power shortages and unreliable access to electricity.
Protein can provide energy, but this is extremely inefficient. This is due to the fact that the energy it takes to make it usable as energy is almost as much as the energy it provides.
I have no idea what this question means. What is high quality energy?
Rubbish in general is not. Some can be used but it is very inefficient to do so.
It is usually not energy that is efficient or inefficient. Rather, the technology used to extract it may be efficient or inefficient. In the case of any heat energy, the upper limit to the efficiency is given by the Carnot equation for heat engines, and depends on the temperature of the heat source, as well as the environmental temperature.
They get there energy from eating their prey just like us humna we get it from eating and drinking and sleeping.
Incandescent light bulbs are inefficient at converting energy into light. They are so inefficient that in many places there is no a ban on the sale or manufacture of incandescent light bulbs in favor of higher efficiency CFLs, LEDs, or halogen lights.
