You have it backwards. Deciduous trees are the ones that lose their leaves in the winter. They're the ones with the colorful leaves in Fall. Conifers are the ones that stay green all year long. They can do that because they have thin needles instead of leaves, and needles don't freeze as easily as leaves do.
Deciduous trees leaves fall in the autumn and rot on the ground and form a mulch which in turn feeds the tree.
No they do not, unless it is one of the few all year round green trees.
It can stay your system for up to 30 days after your last smoke.
it will stay in there for about 2 years
It is because of the presence of chlorophyll in the leaves which enable the trees to make sugar to use as fuel to stay alive.
palm trees and hibiscus trees once the summer is over they just die because they are from worm countrys that do not have winter. If they where in there home they would stay alive for a very long time but here it is about two months.
Evergreen.
No, deciduous trees drop their leaves in the fall, coniferous trees stay green all year round. yes they do Not all conifers stay green all year round, for example the Larch. Evergreens stay green all year round, some are not conifers.
No because when some of the leaves die,it is a gray like other trees except for pine trees
