• Indirect way

• Mark and Recapture Method

What INDIRECT method do ecologists use to calculate population size

• Quadrant Method

• Mark and Recapture Method

• Catch and Release Method

• Direct count method

The largest population that an environment can support is called the

• carrying capacity

• limiting factor

• birth rate

• death rate
