     __What is Death Rate?__ <span style="font-size: 110%; color: rgb(0,0,0);">Death Rate in an Ecosystem is the number of deaths in a population. An example of Death rate would be, if there were 100 geese that died in one year. Then the death rate would be 100 geese per year. Also if there was more then a death rate then birth rate in a population the steps would be death rate>birth rate, population decreases in size. (3)

One big thing they don't usually have is food. Food is a big problem because there could be a lot of organisms in an ecosystem and everyone needs food so they could be fighting over it and there could not be enough for the other organisms. Another problem would be, high amounts of predators. If there is a lot of predators in an ecosystem, all of the other organisms would probably die because of the high amounts of predators. Also the amount of waste in an ecosystem. The waste could carry diseases harming the organisms. (4)

<span style="font-size: 120%; color: rgb(234,6,6); font-family: 'Trebuchet MS',Helvetica,sans-serif;">__2 Types of__ __Death Rate__ There are 2 types of Death Rates. Those 2 types of death rate is Early Death Rate and Late Death Rate. Early Death Rate means the total number of deaths in the early stages of your life. Late Death Rate means the total number of deaths in the late stages of your life.

Overcrowding. It takes up dissolved oxygen because there are so many fish in the water. Also it could be from the high amounts of predators. There could be a lot of predators in the water that they could eat all the fish and there would be no fish left. And then after a while the predators would soon die because they don't have anything to eat because all the fish died. (8)

The rapidly increasing deer population continues to put an unprecedented strain upon woodland ecosystems, agricultural production, residential landscaping, and human health.
 * Population Facts:[[image:http://www.bennersgardens.com/photos/photo_info_deerfact_deer_2.jpg width="200" height="133" align="right" caption="Deer Information, Deer Population, Deer Management"]]**

Information regarding the current deer population varies, but numbers are projected to be somewhere in the neighborhood of 20 million animals. Some suburban areas are experiencing deer population densities as high as 30-40 animals (occasionally reaching 100 or more) per square mile (ecosystems begin to degrade when counts rise above 15-20 deer per square mile).

Most deer information concurs that the majority of these high-density deer population areas are located in suburban environments where expensive landscaping has become a deer's primary food source.
