I believe the answer is Sunlight.
In our world, the bimass of plants (which considered as living things) make up 1000 more population compared to another living organism.
The plants get their food mainly from the photosynthesis process that utilize Sunlight, water, and other nutrients from soil.
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
