I imagine Mordor's ecosystem is entirely based around one organism in various stages of life. As a small organism, it takes material from a chemical seeded in the ground, and energy from the sun.. Making them photoheterotrophs. They gradually progress to larger and larger creatures, with the biggest being up to a mile long. The largest size is responsible for seeding the chemical in the ground, and subsists by feeding on the very smallest, much like a whale feeding on krill. This entire ecosystem is threatened by the native Orcs, who under the leadership of a Hobbit from off-planet, are terraforming a region near the center of Mordor to be more fertile. The Orcs often ride the largest variant of this ecosystem sustaining creature, much to the surprise of all others.
