More consumers than producers
Answer: Water molecules are strongly attracted to each other, so they remain condensed (that is, a liquid, and not a gas) at higher temperatures. Dihydrogen and dioxygen have no strong attractive forces to hold the molecules together, so they exist as gases at room temperature and pressure (that is, in our everyday lives).

Answer:
<u>Digestion</u> is a process by which large ingested molecules are mechanically and chemically broken down to produce basic nutrients that can be absorbed across the wall of the GI tract.
Explanation:
Digestion is the process by which large molecules of food are broken down into molecules small enough to be absorbed by the body's cells, that is, through this process the body obtains nutrients from food to function properly. The organs that perform this function are part of the digestive system. Digestion and absorption takes place in the gastrointestinal tract (GI track), during its passage through this tube, food remains 3 to 5 hours in the stomach, 4 hours in its movement along the small intestine and 6 to 20 hours in the large intestine .

UV is an environmental human carcinogen. It’s the most prominent and universal cancer-causing agent in our environment. There is very strong evidence that each of the three main types of skin cancer (basal cell carcinoma, squamous cell carcinoma and melanoma) is caused by sun exposure. Research shows that as many as 90% of skin cancers are due to UV radiation.
