We are asked how passage B relates to passage A. Passage A discusses environmental modeling, the problem of needed computing power, and proposes a possible solution, which is parallel computing.
Passage B is a more general discussion of parallel systems in nature, and how the concept of parallelism is now being applied to computing.
The two passages are both generally supportive of the idea of parallel computing (the solution proposed in A), and passage B gives us no indication that it is unlikely to be implemented.
