A mammal uses only 1 to 2 percent of its energy in ventilation while a fish must spend about 15 percent of its energy to move water over its gills Explain this huge difference?

i think it because in water oxygen dissolved in the water and it is harder than oxygen concentration in the air.

Is it true that 0.1 percent of the energy in a food chain generally makes it from the sun to quaternary consumers?
no
As one animal eats another animal about percent of the energy is lost as heat?
When you eat something you only get 10% of the original energy that was in the thing that you ate eating it does not take that much energy so I would say that you would get about 10% of the energy the anmial had
How much of the food energy that is taken in by an organism is used for its own life processes?
Producers use about 90 percent of the food energy they make during photosynthesis for their life processes.
Could someone explain the statement without autotrophic organisms heterotrophic life would cease to exist?
sure. where would heterotrophic life get its energy? someone somewhere somehow has to produce it or in this case bind the energy into a usable form which we all eat. if nothing did that then what will we eat??? which,BTW, is why the matrix makes no sense cos energy has to come from somewhere!
What is the difference between mammals and amphibians?
Amphibians lay eggs and do not produce milk. Animals give birth to their young and produce milk. Those are the main differences.
A mammal uses only 1 to 2 percent of its energy in ventilation while a fish must spend?
15%
What is the percent difference between the average kinetic energy and the elastic potential energy?
Why don't you go to the restroom and do poo poo.
What is the solar energy at madhapur used for?
exhaust ventilation fans
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
Attic Ventilation?
In home attic ventilation is very important for several reasons. Excess heat that builds up in the summer can cause energy costs to rise as well as excess cool temperatures in the winter. With attic ventilation, the air can be equalized to better reduce energy costs. Attics can reach a temperature of 140 to 170 degrees in the summer time and can make energy costs soar. If you have poor ceiling insulation in your home, then the heat movement can account for more than 40 percent of the cooling costs. There are many types of attic ventilation. Some of them include wind assisted ventilators, power ventilators or gravity ventilators. Whatever method is used, it is to provide ventilation for proper moisture and temperature. Natural ventilation is the most energy efficient and most common method used. The wind in the home creates a high and low pressure and the ventilation occurs when the air is heated. Wind pressure ventilation has to have a small vent area to get the same results. The low and high pressure changes with wind direction makes it difficult to locate outlets for the ventilation to take place no matter what the wind direction. Natural ventilation is caused when a chimney is present. It is the most economical ventilation. Depending on the opening size determines the quantity of ventilation as well as the temperature and wind. Power ventilation is done one of two ways. Homes that are not air conditioned are controlled by attic fans. These are typically found in the older model homes. They can be very energy sufficient when lowering energy costs. Power ventilation is when the air from the outside is pulled in through the windows and released through the attic; however, the power ventilators can provide ventilation even when there is no wind present. They can also provide temperature control when used simultaneously with a thermostat. Power ventilators are also a great way to bring fresh outside air into the home.
Explain the difference between an object's external temperature and its thermal energy?
The thermal energy of an object consists of the total kinetic energy of all its atoms and molecules. The temperature of the object is a measured average intensity of its thermal energy.
Why is ventilation necessary?
Roof ventilation is necessary so that the air is in constant circulation keeping moisture levels low causing less future damage. Roof ventilation also increases energy efficiency in warmer climates.
The Bohr model of the atom was able to explain the Balmer series because?
differences between the energy levels of the orbits matched the difference between energy levels of the line spectra.
Explain physics in relation to matter and energy?
explain how matter and energy are interrelated
Explain why only 10 percent of the engery available at one trophic level is transferred to the next higher trophic level?
between each tier of the energy pyramid, energy is lost as heat
Why is roof ventilation necessary?
Roof ventilation is necessary so that the air is in constant circulation keeping moisture levels low causing less future damage. Roof ventilation also increases energy efficiency in warmer climates.
How would you explain the difference between potential and kinetic energy?
Kinetic energy is energy related to movement. The formula is (1/2) mass times velocity squared. Potential energy is energy of position. The formula for gravitional potential energy is mgh (mass times gravitation times height).
