Iron makes leaves green. If trees have green leaves, they have iron.
no
Leaves on deciduous trees change colour in the Autumn prior to dropping.
Deciduous.
the pollen and air from the oxygen at this time of year makes the leaves dry up. this makes the roots loose their "hold" of the leaves and the leaves fall
Pine trees leaves do not change colour during autumn, as they are evergreen trees.
Deciduous trees change the color of their leaves before they fall off in autumn.
No not really - most tropical rainforest trees are evergreens and keep their color until the leaves fall off. Certain palm trees do not change color until they die, or fall off too. Eventually yes, but Conifers have smaller leaves so they change slower.
In The Spring Leaves Grow In The Summer Leaves get darker In The Fall Leaves Turn Orange And Die And In The Winter Trees With Now Leaves They Grow As They Change
i do not know
Leaves change color because the trunk of the tree stops sending nutrients and water and other chemicals to the leaves. In the winder, the tree keeps all the nutrients inside and doesn't have the energy to keep feeding the leaves, so they change color and die and fall off. Trees with leaves that do not change color just means that they don't have this process and are most likely in a warmer climate or survive much better in cold
Deciduous trees :)
