Whereas the plants release oxygen and take in carbon dioxide. This is the reason why everywhere across the world all countries are taking major initiatives to plant more treessince it provides more oxygen for all human beings and animal species. In a way trees are balancing out the ratio of oxygen and carbon dioxide in the air which is crucial for our environment. Animal species are also important for our ecosystem since they contribute towards the food chain. The food chain ensure that there is not too much excess of unwanted species or insects since the energy is being transferred on a regular basis. This balances our ecosystem. Therefore, our life is not sustainable without these species because their existence brings equilibriumto our ecosystem.CollapseMark as ReadEcosystems, Goods, and ServicesNatalie Dominguez Email this Author5/16/2015 8:29:54 PMUnderlying all the resources we use, the species we see, and the foods we eat are ecosystem processes: the biological, chemical, and physical interactions between components of an ecosystem (e.g., soil, water, species). These processes produce benefits to people in the form of clean water, carbon sequestration, and reductions in erosion, among others. These benefits are ecosystem services. The ability of nature to help filter, regulate the release of, and capture and store water allows us to wear blue jeans, drink coffee, and eat a hamburger, but we rarely think about the true origin of the products we use every day. Ecosystem services, since they are the benefits from nature, are often discussed in the context of conservation, but in our daily lives we make choices that depend on and affect flows of services from nature, since all goods and products we use today originate from nature and its services.

The clean water, fresh air, good food and materials are the examples of the ecosystem services because all these resources are produced by the environment. Our life is not sustainable without these species. Plants help in balancing oxygen and carbon dioxide which we human and animals inhale and exhale.Animals plays a vital role in process of food chain in ecosystem. All these plants and animals are interconnected with each other.(an instructor response)CollapseMark as ReadRE: Ecosystem, Goods and ServicesProfessor Fam Email this Author5/17/2015 4:05:42 PMPlease more details and references.
