In order to more efficiently show the quantity of organisms at each trophic level, these food chains are then organized into trophic pyramids. [1] The arrows in the food chain show that the energy flow is unidirectional, with the head of an arrow indicating the direction of energy flow; energy is lost as heat at each step along the way.

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.
Evolutionary game theory analyses Darwinian mechanisms with a system model with three main components – population, game, and replicator dynamics. The system process has four phases: 1) The model (as evolution itself) deals with a population (Pn). The population will exhibit variation among competing individuals. In the model this competition ...
In Kluane Lake, Yukon, 750 g (1.65 lb) Arctic ground squirrels (Spermophilus parryii) were the main overall food for Harlan's red-tailed hawks, making up 30.8% of a sample of 1074 prey items. When these ground squirrels enter their long hibernation, the breeding Harlan's hawks migrate south for the winter. [ 129 ]
Hawks feed on a variety of smaller animals such as snakes, lizards, fish, mice, rabbits, squirrels, birds, or any other type of small game that is found on the ground. [23] As an example, red-shouldered hawks eat smaller birds like doves as well as bugs like grasshoppers and crickets. [20]
However, when there’s the hustle and bustle of the 9-5 to contend with and the stressors and strains of daily life, carving out some quality time together can be easier said than done. But that ...
This was in a gold atom known to be 10 −10 metres or so in radius—a very surprising finding, as it implied a strong central charge less than 1/3000th of the diameter of the atom. The Rutherford model served to concentrate a great deal of the atom's charge and mass to a very small core, but did not attribute any structure to the remaining ...
