You don't have to be a tennis player to be affected by tennis elbow, an overuse injury causing pain around the outside of the elbow. Tennis elbow, also known as lateral epicondylitis, is believed to affect around one in three people at any time, most often between the ages of 40 and 60.
Itâs theelement that anchors all organic substances, fromfossil fuels to DNA. On Earth, carbon cycles throughthe land, ocean, atmosphere, and the Earthâs interiorin a major biogeochemical cycle (the circulation ofchemical components through the biosphere from orto the lithosphere, atmosphere, and hydrosphere).
The carbon cycle explains how carbon is made available to life forms. The main processes of the carbon cycle are photosynthesis, respiration, decomposition, natural weathering of rocks and burning fossil fuels. Primary producers use photosynthesis to take in carbon. Plants absorb it from the atmosphere in the form of carbon dioxide. Carbon moves up the food chain when animals feed on plants and the carbon is transferred. While alive, animals release carbon dioxide back into the atmosphere through respiration.
