Scientists found the fossils of numerous indistinguishable showing up species on generally isolated main lands. They had two hypotheses for this. Initially, they conjectured that different species grew indistinguishably over the distant, a profoundly improbable idea. The subsequent theory was that the landmasses had been in contact with one another a large number of years prior, and had by one way or another, floated separated.
These landmasses were in contact at some point previously, enabling species to wander unreservedly, bite the dust, be covered, and become fossilized over these central lands.

The correct answer is A. An oak tree
Explanation:
The term "primary producer" is used to describe organisms that can produce their own energy without feeding on others, this includes plants and algae that produce food and energy through photosynthesis using light and other inorganic compounds. Additionally, the primary producers can be identified because in ecosystems they are always on the first level and they are eaten by others.
According to this, the one that is a primary producer is an oak tree because this is a type of plant and therefore can produce its food through photosynthesis different to others that need to feed on other organisms to obtain energy.
