With such a large increase in human population in a relatively short time period compared to the Earth’s history and humanity’s existence, problems major changes in the…

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.…
