Study of how organisms interact with each other and with their environment.. Can be divided into several levels: . individual, population, community, ecosystem, biome, biosphere. The Aquatic Biome. 3 Basic Areas:. Freshwater. (rivers, lakes). Brackish. Water (estuaries, wetlands). Marine. (oceans, coral reefs). How do ecologist classify?. Salinity. Depth . Whether the water is . Abiotic Elements That Affect Our Water. Water Chemistry. Healthy aquatic ecosystems depend upon many factors. One important factor is the chemical balance present in the ecosystem.. Aquatic ecosystems are susceptible to many chemical changes. Usually if the chemistry of a “healthy” ecosystem changes, signs of this change will include sensitive organisms quickly declining in number or disappearing. These types of organisms are called . 4.2 pgs. 94 - 100. Biomes. A large geographical region with a specific range of temperatures and precipitation, and the organisms that are adapted to those conditions of temperature and precipitation. Explain how biomes are characterized. Describe how net primary production varies among biomes. Explain how organisms are adapted to the conditions of their biomes. Describe the criteria ecologist use to classify aquatic systems. CHAPTER. Too Much of a Good Thing?. Elephant populations in southern Africa declined sharply due to hunting but have made overwhelming comebacks within nature reserves and parks.. Some worry that elephant overpopulation is causing a decline in local biodiversity and damage to farms and infrastructure.. Aquatic ecosystems are primarily determined by the ecosystem’s . salinity. . Salinity refers to the dissolved salt content of the water.. Aquatic ecosystems are divided into freshwater and marine ecosystems.. What are Ecosystems? . Groups of living things and the non-living environment in which they live.. The people that study ecosystems are called: . “ecologists.”. Let’s look at the living parts of the ecosystem:. SUMMER INSTITUTE. June 23-25, 2015. Presented by. UNC INSTITUTE FOR THE ENVIRONMENT. GOOSE CREEK STATE PARK. A TIME FOR SCIENCE NATURE AND SCIENCE LEARNING CENTER. Funded by . THE EDDIE AND JO ALLISON SMITH FAMILY FOUNDATION. Getting started. With this GEO resource you will be learning about the location and biodiversity of . coral reefs. , their value to us and the environment and threats affecting global reefs today. We will also investigate the response to such threats in term of management.. (A) . Abiotic. component. (B) Biotic component. Abiotic. component:. Abiotic. component of pond consists of water, dissolved minerals, oxygen and carbon dioxide. Solar radiations are the main source of energy..
