The exceptions to this general rule are the plants (mostly cacti, bromeliads, and . But data suggests that deciduous and evergreen trees produce similar amounts of oxygen over the course of a whole year, provided they also have a similar total leaf area. Still, at any given moment there is a tree on our planet creating the oxygen that we breathe. 2 Do trees give us air? Do pine trees continue to grow in the winter? "Pine trees one of biggest contributors to air pollution: Pine gases chemically transformed by free radicals." That totals something like 11,000 liters of air (388 cubic feet) in a day. Two mature trees can provide enough oxygen for a family of four.. They use carbon dioxide from the air and water from the soil to make sugar and oxygen. Instead, it uses some carbon dioxide that it makes on its own. Minerals can also be a limiting factor of photosynthesis. Pine trees are one of the biggest contributors to air pollution. These chemicals play a vital role in plants. When the squirrels eat the mushrooms, the spores survive in the squirrels digestive tract and come out in its scat, that is spread throughout the forest. Older trees tend to have less foliage, so there is not as much available chlorophyll to help with the process.

OVERTON - Every year about this time, as ozone levels rise, someone, usually a major polluter, tries to make East Texas pine tree forests the scapegoat. 50% of our earths oxygen is produced by green plantlife and 50% is produced by the phytoplankton which resides in our oceans. Older pine trees produce more oxygen than younger trees, and because pines don't lose their needles in winter, they produce oxygen all winter long. But for most of us, we just dont care. Photosynthesis occurs across the surface of a leaf, and the total oxygen production of a tree depends upon its total leaf area. Evergreens grow best in the winter and throughout the year. Not only do evergreens continue to grow their roots during the colder months (requiring chemical energy manufactured from sunlight, CO2, and WATER), they have to deal with dry conditions, frozen soils, and continuous water loss (demand) from their ever productive foliage. Theyre thick, have less surface area, and are coated with a waxy substance called cutin, which traps moisture within them. Hardy to nearly all zones.
