as far as i understand it. 50% of our earths oxygen is produced by green plantlife and 50% is produced by the phytoplankton which resides in our oceans. Due to the fact that the winter in one hemisphere is the summer in the opposite hemisphere then the earth globally always produces the same amount of oxygen. :)

What trees are pine cones and acorns found in?
Pine cones are produced by pine trees. These are coniferous trees with needle like leaves that are not totally shed in the winter season. The cone that is common to the tree is part of its reproductive cycle Acorns are found in Oak trees. These are a hard wood deciduous tree with leaves that it generally loses during the winter. Again, the acorn is part of the reproduction of the tree.
Are there any trees that keep their leaves in winter?
Most conifers keep their leaves(needles) in winter.9 all evergreen trees keep their leaves throughout the year even in winters like pine trees for example
Why do trees shed their leaves in autumn?
In general all trees sprout new growth come early spring. And some trees gain new leaves after being bare over the winter. Evergreen trees like firs get new growth of needles. And even other trees will burst into bloom, like the Japanese Cherry Trees that are so famous for their pink flowers. Not much happens during the summer. Bot some of the trees that bloomed during the spring start to develop fruit where their flowers once were. The fruit ripens during the summer months and typically are ready for picking by the last month of summer early month of autumn. During late autumn the leaves of the deciduous trees change from green to multiple colors (red, yellow) and eventually fall off leaving the trees bare again for the winter. The evergreens stay green and do not lose their needles, but they do go dormant to conserve energy. During the winter months all trees lie dormant for the most part. The notable exceptions are tropical trees like palm trees, fig trees, and fern trees that stay green and active in the tropical parts of the world.
Why does the colors of the leaves change?
The trees change color in winter (some trees) because the temperature inhibits the synthesis of chlorophyll and therefore the carotenoids or the xanthophyll pigments become in excess in comparison to the chlorophyll resulting in giving different color to the tree.
Why do trees increase moisture in the air?
Trees are provided with numerous leaves and during day time when stomata are open, a lot of water vapours come out by transpiration adding to the moisture in the air. Thus, humidity in the air is largely affected by the density of trees in that area.
What do you call trees when their leaves are gone for winter?
Trees come in two major divisions:Evergreens - the leaves/needles remain green all yearDeciduous - the leaves fall durning the cold months and return in the spring.
What is spring and fall like on earth?
