They provide the most important part of our atmosphere. Without them, we all die.
Definition of matter: that which has mass and occupies space. So yes. =)
There are not enough plants
Why do you drink so much liquid? Because your body needs it... as do plants.
All living things (except plant matter) nead oxygen, and we inhale it to fuel our muscels. What we exhale is Carbon Dioxide. Plants transform Carbon Dioxide into Oxygen during the process of photosynthesis, so as long as there are trees or plants it really doesn't matter.
Dolphins are carnivores so they do not eat plant matter.
When plants and animals die, they decompose (so do humans). All matter especially carbon matter decomposes. Decomposition frees nutrients for other plants, animals, and insects. Dying is nature's great recycler of matter, nutrients, and energy.
No it does not matter where you put the plants in your zen graden
An omnivore is a living creature that eats both plant and animal matter. Centipedes do eat plants and animal matter, so they are an omnivore.
Soils get their organic material from the plants that live, or have lived, in them. Deserts have few plants to provide this material.
More primitive plants have no vascular tissues (or any tissues for that matter), so yes, there are non-vascular plants. Mosses and liverworts (Bryophytes) would be examples.

yes because plants need to stay alive so that the world can grow
