Population Dynamic Lab Report

Purpose: Analyze graphs to determine the population size of two marine species.
Explain how predation, birth, and death rates impact marine populations.
Describe how biotic and abiotic factors influence marine populations.

Research: 1. Prey Initial Size: The starting number of prey. (Assume that the seals have an unlimited amount of food.)
2. Prey Growth Rate: The birth rate of the prey. The larger the growth rate, the faster the prey population will increase.
3. Predator Initial Size: The starting number of predators.
4. Predator Death Rate: The death rate of the predators. A larger death rate means predators will die out quicker.
5. Capture Efficiency: This number represents the ability of the

The birth rate of the seals will decrease of the capacity that they carry, so this will cause the Whales rate to increase. However, the death rate of the Whales will increase when both mammals population.

3. Climate change (an abiotic factor) has slowly decreased habitat for the arctic seals. Predict how a reduction in habitat could change the capture efficiency of the killer whales. How would this
