They are also known as evergreens, needle-leafed trees or softwood trees. The leaves of conifers are very narrow and long or small and scale-like with straight veins. The leaves remain on the tree for two or more years, with the exception of the tarmack which loses its leaves each fall. Many tropical trees are also evergreens. Both kinds of cones occur on the same tree except in juniper and yews where the male and female cones are on separate trees.
Pollination is by the wind.
Any organism that feeds on other plants or animals is a consumer. Consumers are also called heterotrophs which means other feeders. The leaves are wide or broad compared to their length and have net-like or branching veins. Leaves are on the tree for a single growing season. In the autumn the leaves change colour and are shed from the tree before winter.
