Question 1 NECO_MODEL_QUESTIONS_VOL1 • 2019 • AGRICULTURAL_SCIENCE • practical

A farmer wants to assess the diversity of insect pollinators in a 0.5 ha orchard. Four 1 m² quadrats were sampled and the following numbers of individuals per species were recorded:

Question Parts

( a )

State the total number of pollinator individuals observed in the four quadrats.

( b )

Using Simpson's Diversity Index \(D = \frac{\sum n_i (n_i-1)}{N(N-1)}\), where \(n_i\) is the number of individuals of species i and \(N\) is the total number of individuals, calculate \(D\) to two decimal places.

( c )

State whether the orchard has high, moderate or low pollinator diversity based on the index, using the guide: D < 0.20 – high, 0.20 ≤ D ≤ 0.50 – moderate, D > 0.50 – low.

( d )

Suggest one cultural practice that could be adopted to improve pollinator diversity in the orchard.
