if plants had less chloroplasts then they wouldn't be able to get energy from the sun and end up dying
There are different trophic levels at each stage. Trophic levels determine the amount of energy at each stage of the food chain. For example, the energy is 100% at the producer (plant), so it's the 1st trophic level, and so on. Energy amounts decrease as you go up a food chain, and you rarely find more than 5 animals in one because there is not enough energy left for the 6th consumer
This has happened before in Yellow Stone National Park in CA. Removing a species form the Pyramid causes the ecosystem to collapse, as species become over hunted and others are starved. One type of organism could become overpopulated, therefor lack of natural variation.
