Animal Population Chesapeake Bay Population Review that data and draw some conclusions: Did the populations increase, decrease, or remain constant? What was the increase or decrease in populations? What impact might the populations increase or decrease have on the ecosystem? Based on the data, what do you predict will happen with the populations in the area? Why? What will happen if the populations continues in their current trends?

Alaskan Wildlife Population http://www.alaskasealife.org/New/research/index.php?page=ssl_decline.php

Reasons for Animal Population Increases and Declines Increase in human population which leads to the need for more land for us to live in Increased desire of animal skins for clothes Hunting animals for their skins, tusks, horns, meat, etc... Discarding of chemical wastes into rivers kill the marine life Diseases Decline in food sources Increase in predators

Alaska Animal Populations Cause and Effect Cause(s) Effect(s) The population of the ___________increased/decreased from ____ to ____. 1. Looking at the data and what you know about populations, communities, competition for resources, and reasons for increases and decreases in populations, what may have caused this population to decrease? 2. What may be an effect of the population decreasing?

Human Population Chesapeake Bay Population Review that data and draw some conclusions: Where did the growth happen? What was the increase in population? What impact might the population growth make on the ecosystem? Based on the data, what do you predict will happen with the population in the area? Why? What will happen if the population continues to grow?
