Q. No.Select the correct equation for population density at time t+1,
1. \({N_{t+1} =N_t} + [(B + I) - (D +E)]\)
2. \({N_{t+1} =N_t} \times [(B + E) - (D + I)]\)
3. \({N_{t+1} =N_t} + [(B + I) + (D + E)]\)
4. \({N_{t+1} =N_t} \times [(B + D) - (E + I)]\)
1. \({N_{t+1} =N_t} + [(B + I) - (D +E)]\)
2. \({N_{t+1} =N_t} \times [(B + E) - (D + I)]\)
3. \({N_{t+1} =N_t} + [(B + I) + (D + E)]\)
4. \({N_{t+1} =N_t} \times [(B + D) - (E + I)]\)
