The number of individuals needed for the long-term survival of rare and endangered species is defined as viable population size.

Which piece of equipment can be used to estimate the population size of a given species in a defined area?CalculatorTransectQuadratTape measure2A student measures the number of snails in a garden by taking 10 random 1 m2 quadrat readings. If the numbers recorded are 3, 2, 1, 4, 2, 4, 5, 5, 2 and 2, what is the mean number of snails per m2 in the garden?302343A field measures 10 m by 30 m. In ten 1 m2 quadrats thrown randomly onto the field, an average of 5 flowers is counted.
