PPT-Aquatic ecosystems are grouped based on abiotic factors such as water flow, depth, distance

Section 3 Aquatic Ecosystems K What I Know W What I Want to Find Out L What I Learned Essential Questions What are the major abiotic factors that determine the aquatic ecosystems What are transitional aquatic ecosystems and why are they important. and . Abiotic Factors. Ecosystems: . Abiotic . Factors. Ecosystems support life. Living things depend on the environment. You would not find a kangaroo in the Arctic and you won’t find a polar bear in Australia.. the study of the relationships between biotic and abiotic factors in environments. eco.

Freshwater is less than 3% of the Hydrosphere. . 90% of the freshwater is locked beneath the Earth’s surface. . Water is cycled through evaporation and transpiration from the atmosphere to the land and back again. . All . ecosystems. contain biotic and abiotic factors. Biotic. = living features. Abiotic. = non-living physical features. Relationship between biotic and abiotic factors is important to ecosystem health. Unit A: Sustainability of Ecosystems . Ecology. 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 . Sustainable Ecosystems. Ecology is the scientific study of the abundance and distribution of organisms, and of their interactions with their environment. Oikos = house. Logos = to study. Ecology uses the scientific method of hypotheses and deductions.. 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.. Keywords for today. Biotic. Abiotic. Climate. At the end of today’s lesson you will be able to . Define biotic, abiotic, . and climate. Give examples of each type of factor. What factors both living and non living will affect my life?. -Ecosystem. -Biotic. -Abiotic. -Abiotic Factors. Biosphere.
