So the light can shine through. If there is no light reaching the lens and surrounding the subject, then one would be unable to see
The sun sends more energy to the earth every day then humans currently consume. The problem is that we are unable to capture more than a small percentage of this energy.
Pure economics. It costs more to use "non-conventional" energy sources.
The law of conservation of mass states that mass cannot be created or destroyed. This is not strictly correct, as mass and energy can be inter-converted, as in nuclear reactions. Thus, 'mass and energy cannot be created or destroyed' is more accurate.
Food is cooled from surrounding air particles and so if a packet is obstructing the vibration of the particles the food will be unable to cool.

They die
Plants make their own food because they are unable to get nutrience from other sorts of places. Animals are able to get their energy from other animals and plants, however plants are unable to do this. Plants are primary producers in ecosystems because they are were energy initially enters the system.
If you are asking why a green heating system will not go above 68 degrees Fahrenheit then one reason is to save energy. The higher the temperature the more energy required to get to that temperature and the more energy required to keep that temperature.

While there are more advantages than disadvantages of a monogastric digestive system, there are still disadvantages that exist. Animals with a monogastric digestive system are unable to extract energy from the cellulose that they consume in their foods.
The adaptive immune system is activated if the innate immune system is unable to control the infection.
Immortal.
The autobots are unable to answer this question.
It is easier for your body to swallow and digest well chewed food to get the nutrients and energy you need (especially meats and grains). If you don't chew your food properly, your digestive system needs to put as much energy into getting the energy out of the food, as it actually gets out of the food. Also, the digestive system is unable to get all of the nutrients out of the food before it is excreted.
The human body is unable to convert the sun's energy to carbohydrates because it has no photosynthetic structures.Plants do have such structures, called chloroplasts, which contain chlorophyll, which is a photosensitive chemical which transforms energy from light into chemical energy to help break water into hydrogen and oxygen, and break carbon dioxide into carbon and oxygen, so they can re-combines into assemblages of carbon, hydrogen, and oxygen, otherwise known as carbohydrates.
