Answer:
Lichens are not parasitic when they grow on trees, they just use the tree bark as a home. They enrich the soil by trapping water, dust and silt. When lichens die they contribute organic matter to the soil, improving the soil so that other plants can grow there.
I’d say conical shape- coniferous trees are known for this shape.
Hey there!
Here is a paraphrased version of the text:
Objects that are nonliving never had the qualities of life, and never will. Things that are dead did have an experience to have the qualities of life, but then they eventually die, they fail to keep some of the characteristics. So in science, dead is not an identical word to nonliving. A rock is nonliving, a fallen tree is dead, and a moose is living.
Note: While paraphrasing a text, a good thing to do is to think of as many synonyms of the words in the text as you can.
Hope this helps you.
Have a great day!
