It is believed that a primordial eukaryotic cell was in a symbiotic relationship with mitochondria-like bacterium. The primordial cell eventually engulfed the mitochondria-like bacterium for ATP production to power itself.
<span>Ecologists study populations by studying changes in growth rates, distributions and genetic compositions. I think through population studies, ecologists can get an idea about the conditions that are influencing the populations being studied. They can also discover how these changes would impact other interacting populations.</span>
