photosynthetic pond organisms.<\/strong><\/li> <\/ul>\n[embed]https:\/\/vimeo.com\/462251158[\/embed]\n<p style=\"text-align: left;\">In this section we are at different lakes.<\/p> <p style=\"text-align: left;\">Lakes contain water that primarily stays within a basin.\u00a0 There can be water movement on the surface or some water entering and leaving, but the bulk of water is not moving from one point to another (like in a stream).<\/p>\n<p style=\"text-align: right;\">Ponds are small lakes that can be strongly impacted by seasonal changes, sometimes completely freezing or drying out.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/11\/pond-or-lake-scene-1-1024x655.jpg\" width=\"1024\" height=\"655\" title=\"7a3 Lakes\" alt=\"7a3 Lakes\">\n<p style=\"text-align: center;\">Lakes are classified based on <strong>productivity<\/strong>, the amount of photosynthesis occurring in lake producers.<\/p>\n[embed]https:\/\/vimeo.com\/434950528[\/embed]\n<p style=\"text-align: center;\"><strong>Oligotrophic<\/strong> lakes have low levels of productivity, these are often clearer water.<\/p> <p style=\"text-align: center;\"><strong>Mesotrophic<\/strong> lakes have a middle level of productivity, enough photosynthesis to support a more complex food web.<\/p> <p style=\"text-align: center;\"><strong>Eutrophic<\/strong> lakes are high in productivity, so high they can be green in color.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/11\/lake-prod-1024x414.jpg\" width=\"1024\" height=\"414\" title=\"7a3 Lakes\" alt=\"7a3 Lakes\">\n[embed]https:\/\/vimeo.com\/466903056[\/embed]\n<p style=\"text-align: left;\">A highly eutrophic lake or pond can be \"too much of a good thing.\"\u00a0 This video explains why.<\/p>\n<p style=\"text-align: center;\">Crater Lake is an example of an oligotrophic lake.\u00a0 Productivity is low and the water is clear to well over a meter below the water's surface.<\/p>\n<p style=\"text-align: center;\">Within a single lake, there are different zones that are impacted by the amount of available light and nutrients.\u00a0 Each zone can have its own organisms.<\/p>\n[embed]https:\/\/vimeo.com\/434950166[\/embed]\n<p style=\"text-align: center;\">The <strong>Littoral<\/strong> lake zone is the area near shore that is shallow enough for light penetration.\u00a0 Many amphibians and aquatic insects spend part of their life cycle here.<\/p> <p style=\"text-align: center;\">The <strong>Limnetic<\/strong> lake zone is the open water area that sunlight penetrates.\u00a0 Many large fish swim here.<\/p> <p style=\"text-align: center;\">The <strong>Benthic<\/strong> lake zone is the bottom, below the sunlit limnetic zone.\u00a0 Although light is low, nutrients are high and scavengers like crayfish and catfish can be found here.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2020\/07\/shutterstock_1316460533-1024x1024.jpg\" width=\"1024\" height=\"1024\" title=\"7a3 Lakes\" alt=\"7a3 Lakes\">\n<h6 style=\"text-align: left;\">Some species utilize different zones in a lake during different life stages.\u00a0 For example, fish eggs may be laid on plants in the near shore littoral zone, but later stages of larger fish may swim and eat in the open limnetic zone.<\/h6>\n\n<h5>For this guide's media piece you will be identifying organisms from a small pond.\u00a0 To complete this successfully, we will start by introducing common categories of pond organisms and then introduce the assignment.<\/h5>\n[embed]https:\/\/vimeo.com\/474534384[\/embed]\n<p style=\"text-align: left;\">This video introduces some of the consumers and producers, both microscopic and macroscopic, that we may encounter in a pond sample.<\/p> <h6>\u00a0<\/h6>\n<h3 style=\"text-align: center;\">Freshwater Producers<\/h3>\n<img

left;\">Eutrophic lakes and small ponds are typically very productive, meaning there are many producers, including algae and plants.\u00a0 Producers carry out the process of photosynthesis.<\/h5>\n<h5>These are common microscopic producers that you are likely to find in a lake or pond.<\/h5>\n<img
