convergent evolution - called analogy
a potential source of confusion in constructing a phylogeny is similarity between organisms that is due to convergent evolution - called analogy - rather than to shared ancestry. thus for mammals, the backbone is a shared ancestral character, a character that originated in an ancestor of the taxon
Answer:First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.
Explanation:
The features of the seafloor and the patterns of magnetic polarity symmetrically about the mid-ocean ridges were the pieces that Hess needed. ... As oceanic crust forms and spreads, moving away from the ridge crest, it pushes the continent away from the ridge axis.
Primary consumers are those that are herbivorous - they only eat producers. Primary consumers are the link between the base of an ecosystem's chain food - where simple substances are transformed into organic compounds by photosynthesis or chemosynthesis - and the upper layers - where energy is obtained from, mostly, other animals.
If primary consumers were not found in an ecosystem, all other layers of the chain food on that ecosystem would be nonexistent. The ecosystem would only be made by producers.
