A nucleon resonance with spin-parity J(P) = 3/2(-) and mass about 2.1 GeV is essential to reproducing the photoproduction cross sections for Lambda(1520) released by the LEPS and CLAS collaborations. It can be explained as the third nucleon resonance state [3/2(-)](3) in the constituent quark model so that there is no position to settle the N(1875) which is listed by the Particle Data Group as the third N3/2(-) nucleon resonance. An interpretation is proposed that the N(1875) is from the interaction of a decuplet baryon Sigma(1385) and an octet meson K, which is favored by the calculation of binding energy and decay pattern in a Bethe-Salpeter approach.
