Concept explainers

Modes of Nutrition

It is a biological process of providing or obtaining food that is necessary for growth and health. It includes many physiological processes - absorption, ingestion, assimilation, catabolism, excretion, etc. In biology, the science that deals with nutrition's physiological and chemical processes are called "nutritional science."

Question

About how much mercury was emitted by fossil fuel combustion in Asia? A.)340 tons B.)0 tons C.)40 tons D.)525 tons

Mercury is a naturally occurring element that is toxic to humans and other animals. Mercury that is released into the atmosphere eventually falls to Earth, where
it can enter the food chain (usually through fish and shellfish). In humans, mercury can damage the nervous system, kidneys, and other organs. Large amounts of
mercury exposure can result in memory impairment, coma, and death.
Most mercury on Earth is trapped in rocks and is released naturally through geologic processes. However, human activities are causing large amounts of mercury
to be released into the atmosphere. The increased output of these pollutants puts both the environment and humans at greater risk.
