A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
By removing the phytoplankton, quaggas, in turn, decrease the food source for zooplankton, therefore altering the food web. Impacts associated with the filtration of water include increases in water transparency, decreases in mean chlorophyll concentrations, and accumulation of pseudofeces. Water clarity increases light penetration, causing a ...
There are many ways that the soil food web is an integral part of landscape processes. Soil organisms decompose organic compounds, including manure, plant residues, and pesticides, preventing them from entering water and becoming pollutants. They sequester nitrogen and other nutrients that might otherwise enter groundwater, and they fix ...
The Zhemchug Canyon’s rich biodiversity is sustained by the dense population of phytoplankton which thrive on the nutrient rich waters that propelled up by the canyon's contours, a process where the physical shape and structure of a canyon causes nutrient-rich water from deeper regions to surface. The phytoplankton are vital to the ecosystem ...
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...

Filter feeding: A form of food procurement in which food particles or small organisms are randomly strained from water. Deposit feeding: obtaining nutrients from particles suspended in soil; Fluid feeding: obtaining nutrients by consuming other organisms' fluids; Bulk feeding: obtaining nutrients by eating all of an organism.
Dr. Molly shared information that we all already know, but it was still a good reminder. Overall, it sounds like her focus on exercise and mental health play into the other factors. I also ...
