In an ecosystem, a deer consumes grass. what percentage of energy will the deer acquire from the grass?

10% of total energy available in grass.

Explanation:

The energy transfer in an ecosystem occurs through the food chain and follows the 10% law and the second law of thermodynamics. Accordingly, during the transfer of energy from one trophic level to other, only 10% of energy is transferred and the rest 90% is lost as metabolic heat.  

Hence, the grass will use 90% of its total energy content in respiration and this energy will be lost as heat to the surroundings. Only 10% of the energy of grass will be available for deer.  

b, acidosis

acidosis is when the human body attempts to return the bloods ph levels back to normal when the blood is acidic
