How does CO2 Emissions Affect the Ecosystem? Kenyetta Sloan Bryant & Stratton College Ecology Dr. M. McLellan-Zabielski October 24‚ 2012 What would happen if we didn’t cut trees‚ use transportation‚ even turn on our lights or any electrical item we own? Then global warming wouldn’t exist. The things that we do on the daily basis is what produces carbon emissions‚ when we burn oil‚ coal‚ and gas‚ it releases carbon dioxide into the atmosphere. The result of this is climate change‚ temperature

The Impact of Humans on the Biological Diversity of Natural Ecosystems Introduction Since humans have come into existence they have always been a cause of change of whatever natural areas they inhabit along with the living organisms of those natural areas. The different types of organisms such as plants‚ animals‚ and microorganisms that inhabit these areas are known as biological diversity or biodiversity. (USEPA 2010 ) Biological diversity can be affected by many different things‚ climate change

According to UNDP.org (2010)‚ the activities of microbial and animal species – including bacteria‚ algae‚ fungi‚ mites‚ millipedes and worms – condition soils‚ break down organic matter‚ and release essential nutrients to plants. These processes play a key role in the cycling of such crucial elements as nitrogen

human use. 3. Ecosystem capital includes the goods and services produced by the species within an ecosystem and the interactions between the biotic and abiotic portions of ecosystems. Ecosystems are expected to produce something of economic value. Natural resources are only those items in an ecosystem that have a monetary value and things with a monetary value are not a resource. Ecosystem capital does not require that a monetary value is known or exists. All that matters with ecosystem capital is that

organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water that keep the ecosystem growing and balanced. A biome is a geographical
