Elephants are the largest land animals worldwide, used in tourism in several countries, and are often gentle to humans despite their gigantic sizes. However, the elephant population has fallen ...
The African elephants have two finger-like extensions at the tip of the trunk that allow them to pluck small food. The Asian elephant has only one and relies more on wrapping around a food item. [31] Asian elephant trunks have better motor coordination. [43] Asian elephant drinking water with trunk
The rate of biomass production of an organism is required, which involves measuring growth and reproduction through time. There is still the difficulty of assigning the organisms to a specific trophic level. As well as the organisms in the food chains there is the problem of assigning the decomposers and detritivores to a particular level.
Elephantidae is a family of large, herbivorous proboscidean mammals which includes the living elephants (belonging to the genera Elephas and Loxodonta), as well as a number of extinct genera like Mammuthus (mammoths) and Palaeoloxodon.
The relationship between body size and rate of population growth has been demonstrated empirically, [30] and in fact has been shown to scale to M −1/4 across taxonomic groups. [27] The optimal population growth rate for a species is therefore thought to be determined by the allometric constraints outlined by the MTE, rather than strictly as a ...
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.

Elephants can still be incredibly lethal creatures, and it’s far easier to simply kill an elephant and then take their tusks. Even if it were a painless procedure, many elephants rely on their ...
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 ...
