Question

what does the rule of 70 calculate? birth rate of a population how long it takes for a population to double the carrying capacity of the habitat

Explanation:

The rule of 70 is a formula used to estimate the doubling time of a quantity (like a population) growing at a constant exponential rate. It is calculated as \( \text{Doubling Time} \approx \frac{70}{\text{Growth Rate (in \%)}} \). The birth rate is calculated differently (e.g., number of live births per 1000 people in a year), and carrying capacity is the maximum population an environment can sustain, not calculated by the rule of 70. So the rule of 70 calculates how long it takes for a population to double.

Answer:
