2013 Aquatic Ecosystem Function An ecosystem can be defined as “all the organisms in a given area as well as the abiotic factors with which they interact” (Reece et al. 2010). Common aquatic ecosystems range from the largest oceans to the smallest creeks‚ but each aquatic ecosystem plays a pivotal role in global ecology. Each ecosystem consists of important aspects including nutrients cycling‚ biodiversity‚ and energy flow that contribute to the overall state of the ecosystem. However‚ the limited

Topic: Endangered Species Issue Question: Should Endangered Species be Protected? Since the appeared of the first life on this planet‚ numerous species come and go‚ rendered extinct by natural changes in physical and biological conditions. Because extinction is a natural part of the order‚ if there are many other species still exist‚ some people might wonders why or what so unique about the endangered species that large sum of money and effort is spent in order to save and restore them (Why

Keystone species are extremely important in ecosystems across the world. They help control things like population‚ abiotic and biotic life‚ and impacts on human life. Keystone species essentially control the functions of the environment they live in‚ and provide positive and negative effects. In class‚ we studied the effect that wolves had on the environment of Yellowstone National Park. Now‚ I introduce Grizzly Bears and Beavers as my two examples of a Keystone Species. Beavers completely change

observed process of change in the species structure of an ecological community over time. Within any community some species may become less abundant over some time interval‚ or they may even vanish from the ecosystem altogether. Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession".

Man Made Ecosystem By: De Belen‚ Bea Dela Cruz‚ Haydee Dofredo‚ Alona Jane What is Ecosystem? An ecosystem includes all of the living things (plants‚ animals and organisms) in a given area‚ interacting with each other‚ and also with their non-living environments (weather‚ earth‚ sun‚ soil‚ climate‚ atmosphere). Importance of Ecosystem. Ecosystems are communities of living things and the environmental features that support them. Ecosystems are essential to human life‚ providing us with innumerable

1) Natural VS Logging areas The results of the diversity index analysis show that the NF area is the highest (H’ = 1.57). The minor is the MD area (H’ = 1.55) and the HD area (H’ = 1.37)‚ respectively. The LD area is the lowest (H’ = 1.35). This is consistent with Edward et al.’s report (2011) who studied about degraded lands that are worth protecting: the biological importance of Southeast Asia’s repeatedly logged forests found logging had little effect on the overall richness of birds in the once-logging

Through Colorado ’s Ecosystems Grand Lake‚ CO By: Principles of Ecology Biology What makes Colorado so majestic and grand? This beautiful state has eight different ecosystems according to the Denver Museum of Nature and Science. Each strategically placed ecosystem has its own uniqueness. These unique areas can also be called a Biome. To define an Ecosystem‚ we say that there are numerous species of plants and animals that make homes in these different areas. This includes the

A wetland is a land area that is saturated with water‚ either permanently or seasonally‚ such that it takes on the characteristics of a distinct ecosystem.[2] Primarily‚ the factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation that is adapted to its unique soil conditions. Wetlands consist primarily of hydric soil‚ which supports aquatic plants.[3][4] The water found in wetlands can be saltwater‚ freshwater‚ or brackish.[4] Main wetland types

Invasive Species Threatens the Ecosystem Every life form all over the world depends on the ecosystem for its survival. However‚ the ecosystem can be threatened when there is an excess or drop in resources. Many people will argue that human beings are the primary cause of this economic imbalance‚ but are people the root of this problem? No. There is evidence that many invasive species all over the world has also threatened the ecosystem. All organisms have the potential to become invasive
