For wood, to prevent soil erosion, for shade, as a wind break, to provide a habitat and because they are nice to look at
They do not. All green plants make oxygen. Something else growing in there is using up oxygen.
Trees and other plants do not move unless something else moves them. They are fastened into the earth by roots and do not move around.
oxygen for humans and carbon dioxide for plants
nah nothing
trees,Water,Oxygen,Timber,Fruits and vegetables,and Meat from animals.and anything else that can be used again :)
im pretty sure that deforestation is when people chop down trees in one large area of a forest. problems this can cause are mostly environmental, for example, alot of animals make their homes in trees and if the trees are cut down then they will have no where else to live. also, oxygen comes from trees and without the trees there will be no oxygen, and without the oxygen, we will all die. :) hope that helped.
The plants and tree grow food for themselves, everything else eats everything else.
Grass, Other animals accidants
Field mice eat plants, trees, and pretty much anything else.
well to give you a basic idea, plants produce food(fruitandvegies) and when the animal trys to get it it transports the seeds usually by eating the seeds and delivering it somewheres else usally in scat,plus most plants like trees make oxygen from co2, which is a waste product from our breathing.
The primary natural sources of oxygen on Earth are photosynthesis by plants and algae, which convert carbon dioxide into oxygen, and the oxygen produced by marine phytoplankton through the process of photosynthesis. Additionally, oxygen is released during the process of weathering of rocks and minerals.
None existent. Without plants we would have no oxygen to live by, as the plants produce this. We couldn't eat plants, and neither could any other animals. There would be a shortage of food as cows, chickens, and pretty much anything else dies out. Although this wouldn't matter as we'd be dead from the lack of oxygen. Basically no plants = no oxygen and no food.
