Green swirls across the spheres. It fills the oceans and covers the land. Staggering varieties of life, from miniscule cells eating chemicals or each other or the light from the surrounding web of explosions, to larger arrangements that - still eat all those things, and is arranged and formed in countless variations on the same few themes. It seems to move in fast-forward, blossoming from single points and churning, churning, until it covers everything.
Plants. Mosses, lichens, trees, grasses, shrubs, tubers, flowers, fruit. Unmoving, but voraciously competitive none the less, seeking to expose their surfaces to the bright nebula.
Fungi. Using tendrils that slowly creep to eat their food, consuming the fallen for they do not resist, sending spores not seeds to make more of themselves. Slow and subtle and weird.
Insects and invertebrates. Crawling and walking and flying and simply sitting in the water, consuming the plants and each other, some acting alone and some forming hives of hundreds of individuals.
Vertebrates. All manner of things that swim and crawl and climb, most not that much larger than the insects. They sense the world around them in more detail, reacting without comprehension.
Living crystals, in a few places where there is very little water. They eat and grow and compete and reproduce just like the others, though they work in wholly different ways.
All of it competing with itself in strategies to get more food, to avoid being food, to reproduce more, to combine genes with the most successful others.
It's gloriously chaotic, with impromptu systems coalescing, becoming unstable, falling apart, being supplanted by a new system, and the cycle repeating. Whole kinds of beings are destroyed to the last, gone forever, while new variations spring up by chance in the random combining and splitting and reproducing. But all of these beings are, in the end, acting according to their own nature. If you study any of them enough, you can learn to predict exactly how it will react to any other stimulus, even if the system as a whole is too chaotic to capture in every particular.
