Evolution is change over time. This can refer to the organisms as well as the non-living environment. An ecosystem includes all the organisms and their interaction with the non-living environment. As evolution occurs, the dynamics of the ecosystem will change as well. For example, when vertebrates first evolved the ability to move to the land, as seen in the Age of the Amphibians, the ability to exploit new territory, different than simply the water, opened up new opportunities. Different food chains would be exploited, this time on land. All of this would in turn, affect the resources available in both places, land and water. Resources  that would be affected would be  the respiratory gases, humus and soil production, water, space and food.
