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 ...
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.
A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.
The bigger the fish, the higher on the food chain and the more junk there is in there. For people who can’t afford organic food, a vegetarian diet is still healthier even if it contains foods on ...

Research also links a high-fiber diet with improved cognitive function in adults over 60 years of age. Fiber-rich foods include beans, whole grains, nuts, seeds and many fruits and vegetables.
Each cycle involves five days following the plant-based diet—high in unsaturated fats and low in protein, calories, and carbohydrates—and 25 days of your typical eating habits.
The grass can hinder water circulation and drainage or block boating channels. Meadows of S. alterniflorus can crowd out native species, reducing biodiversity and altering the environment; as a result of S. alterniflorus 's growth, invertebrates that live in mud flats disappear as their habitat is overgrown, and in turn, food sources shrink for ...
