Answer:
All the organisms (plants and animals) require energy for performing various activities and maintaining their life. This energy is obtained by the breakdown of digested food during the process of respiration. The process of releasing energy from food is called respiration.
Most energy comes from the sun, either directly or indirectly: Most life forms on earth get their energy from the sun. Plants use photosynthesis to capture sunlight, and herbivores eat those plants to obtain energy. Carnivores eat the herbivores, and decomposers digest plant and animal matter.
Two ways that living things get their energy is by, Cellular Respiration and Photosynthesis.
Cellular Respiration: Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Photosynthesis: it's process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by product.
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

Blood is a mixture of a variety of materials. Some of the materials are dissolved in the fluid portion of blood. Other materials, such as blood cells, do not dissolve but move along with the blood.

Explanation:
Selection pressure means factors that contribute to selection which variations will provide the individual with an increase chance of surviving over others. Because of selective pressures, organisms with certain phenotypes have an advantage when it comes to survival and reproduction. Over time, this leads to evolution.
Answer:
Drying one load of laundry a week puts 0.1 metric tons of CO2 into the atmosphere. Hang 'em outside and save yourself $11 in electricity costs while you're at it. Gym rats, beware: Running on a treadmill for 30 minutes three times a week will boost your carbon footprint by 0.07 metric tons per year
The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. ... Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes.
Meat, cheese and eggs have the highest carbon footprint. Fruit, vegetables, beans and nuts have much lower carbon footprints.

The explanation is given in the explanation section.
Explanation:
Living organisms make biomolecules, and they are made because of their functional characteristics. Most of the biomolecules do not exist outside of living organisms because they are too complex to be created by chance chemical collisions.
The four primary purposes of biomolecules are:
- Structure (some proteins)
- Energy storage and release (carbohydrates)
- Protective layers (lipids)
- Information storage and communication (DNA, RNA, endocrines of numerous various types and manipulated molecules, such as fatty acids)
