<span>Two prokaryotes turning into a eukaryotic cell began with a process called
endosymbiosis. One large prokaryote engulfs (a process called
endocytosis) one small, aerobically respiring prokaryote. The small
prokaryote turned into a membrane-bound organelle, which prokaryotes do
not have, and like we know, only eukaryotes have membrane-bound
organelles. So that is how the eukaryotic cell structure evolved from
prokaryotic cells, meaning that before this evolution, they were most likely symbiotic.</span>
<span>The mouse and rabbit both have a competitive relationship. They both have a place in a similar class. They are in the group of mammalia. There are environmental connections of which two are oppositional and four are harmonious. The oppositional connections are predation and rivalry.</span>
Organisms get the energy they need from food just like us humans do.
