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.
They don't turn grass into meat!! They turn it into ENERGY by eating it. _________________________ The energy is wasted in execration, respiration etc. Not all the energy is consumed as biomass on the sheep.
No, it is a very unreliable and inefficient energy source.
For energy production it is very inefficient.
They are incredibly inefficient.
It is presently inefficient.
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
in a light bulb, electrical energy is converted into light and heat energy. mainly heat (lightbulbs are relatively inefficient)
How Does A consumer Get its Energy: by eating.We get energy by eating food.
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.
The thermal energy output of the new engine was inefficient, as the thermometer quickly demonstrated.
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.
A herbivore gets its energy by eating plantsHerbivorous animals acquire energy by eating plants.
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.
Energy can be created by eating the right choice of foods, not eating too much, and not eating too little.
Energy is transferred from one level to the next as organisms are consumed. The transfer is inefficient as 90% of the stored energy is lost as heat when that stored energy is burned.
We get energy by eating food.
Monkeys get there energy by eating!
THey obtain energy by eating consumers and producers.
chemical energy is the kind of energy
It depends on the size of the turbines. Generally wind turbines are inefficient.
