An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although

Ecosystems and Economics Megan Wells BIO280 April 29‚ 2013 Kalista Andropolis Ecosystems and Economics Human society has placed an imprint on ecosystems throughout the planet. Because of this imprint ecosystems have degraded dramatically and have experienced loss. Human activity has affected plants‚ animals‚ and ecosystem dynamics in many ways. The purpose of this paper is to explore the causes of human society’s impact on ecosystems and the cost and benefits of human enterprises. In

The Desert Biome Natashia Granger Bio/101 The Desert The desert is a dry barren area of land; it is in the Southwestern United States or areas of extreme heat and dryness. Deserts characteristically receive less than ten inches of precipitation a year. About one fifth of Earth’s surface is desert. Desert can be hot or cold

Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting

Environmental Impacts on Ecosystems Introduction An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. Ecosystems are controlled both by external and internal factors. Once outside factors affect these systems

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". why it occurs Every species has a set of environmental conditions under which it will grow and reproduce most optimally. In a given ecosystem‚ and under that ecosystem’s

The marine biome is one of the largest biomes on the earth. It spans three fourths of the earths surface. It includes all five oceans the Arctic‚ Indian‚ Southern‚ Atlantic‚ and Pacific. In it There are many many types of fish and also some mammals. The oceans span wide and deep. There are also plants in the ocean. The ocean is a vast and mysterious place where we are still discovering many things about it everyday. The physical attributes of the ocean depend on which ocean you explore‚for example
