1.4 Typical Trends in Freshwater Food Chains A typical pond food chain is much more complex than simple predator-prey relationships. In every natural environment, In all ecosystems, a food chain takes on a linear structure that has much to do with the size of each organism and its abundance. Every link on this chain consists of a Example of a typical freshwater pond ecosystem food chain. The typical pond food chain is much more complex than just simple predator-prey relationships. It involves microorganisms that must generate their own food when a sufficient set of nutrient building blocks are available. It also involves microbes that are responsible for breaking down waste to free up these same building blocks. Primary Source of Energy in Ponds: Sunlight Many photosynthetic organisms compete with each other for sunlight in the water column. At the very base of the pond food chain are plants and microorganisms that rely on sunlight to survive. Thus, light is a limiting factor that largely determines the abundance of a pond’s biotic components. All throughout the water column, an incalculable number of photosynthetic organisms compete with one another for access to sunlight. When provided with adequate light exposure, they can assimilate the nutrients that are found throughout the water column. Unlike photosynthesizing organisms ( Trophic Levels in Freshwater Ponds Primary producers Primary producers, including submerged aquatic plants, produce their own food. Freshwater po...

Generations of Americans are accustomed to the food pyramid design, and it’s not going away. In fact, the Healthy Eating Pyramid and the Consumers can think of the Healthy Eating Pyramid as a grocery list: • • The Healthy Eating Pyramid also addresses other aspects of a healthy lifestyle— • The Healthy Eating Plate and the companion Healthy Eating Pyramid summarize the best dietary information available today. They aren’t set in stone, though, because nutrition researchers will undoubtedly turn up new information in the years ahead. The Healthy Eating Pyramid and the A look back: Problems with the Food Guide Pyramid and MyPyramid Translating nutrition advice into a colorful pyramid is great way to illustrate what foods make up a healthy diet. The shape immediately suggests that some foods are good and should be eaten often, and that others aren’t so good and should be eaten only occasionally. The layers represent major food groups that contribute to the total diet. The problem with the US government’s original Food Guide Pyramid, released in 1992, was that it conveyed the wrong dietary advice. And MyPyramid, its 2005 replacement, was vague and confusing. With an overstuffed breadbasket as its base, the Food Guide Pyramid failed to show that whole wheat, brown rice, and other whole grains are healthier than refined grains. With fat relegated to the “use sparingly” tip, it ignored the health benefits of plant oils—and instead pointed Americans to the type of low-fat diet tha...

Product Management tools + Software Architecture tools. Marketing campaign planning, brainstorming and asset organization. Process, Value chain and System analysis tools. A visual workspace for students and educators. Food webs are part of an ecosystem, and can be used to simplify and understand the connections between different kinds of organisms, including their behavior and interactions. A food web visually maps out the interconnections between producers and consumers, containing all the food chains of an ecosystem. Ecologists and biologists use food webs to study and understand the relationships between different organisms and their roles in an ecosystem while environmental managers and conservationists also use food webs to inform management and conservation decisions. Creating food webs collaboratively with a group of peers can help better understand the complex relationships of an ecosystem. • Open a Creately workspace and add your peers as collaborators with edit access allowing them to work on the food web diagram with you in real-time. • Define the ecosystem you want to study by identifying the specific geographical areas, climate, and habitats, and what species of plants and animals are found there. • Collect all data and information on as many producers and consumers as possible within your chosen habitat; th...
