This happens because the quantity of energy available in the organisms as food to the next trophic level decreases as you move through the food chain. For example, there may be 1000 Calories of food available if you eat the grass in a section of meadow, but only about 100 Calories in the grasshoppers in that section of meadow. That may not be enough food to support the things that eat grasshoppers, and so on. This limits the length and diversity of food chains. The longest and most complex food chains are in the open ocean!
because a food chain only shows one way energy could flow, while a food web shows multiple ways. For example, a food chain might say: grass-mouse-hawk. but it could also say: grass-mouse-snake-hawk. Or even: grass-mouse-weasel-hawk. However, a food web might show all of these.
the difference between the food chain and the food web is the food chain is the linear transfer of energy from one organism to the next. And the food web is the complex interconnecting food chains in a community.
because when the food chains goes up into the top it decreases the food or its simply when A large amount of producers at the base of the pyramid will be needed to support only a few of the consumers at the top and it called trophic level because when the food chain goes to another level it called survival of the fittest..
Well the staple of the food chain would be plankton. Remember a producer is the base of all food chains. Except in a few rare cases, such as deep sea vents and caves with no light.
At the top of food chains are apex predators, which are organisms that have few or no natural predators of their own. Examples include animals like lions, great white sharks, and bald eagles. These species play a crucial role in maintaining ecosystem balance by regulating the populations of other species below them in the food chain. Their presence helps ensure biodiversity and the health of their habitats.
Generally it's the same thing. Technically albeit the food web is a sort of graph that shows where energy is delivered through animals. (for example energy from phytoplankton go to clams which then goes to seagulls.) While a food chain shows in what order each animal is on a chart depending on how many predators they have. (for example mice have many predators and will be at the bottom of the food chain, while lions have few predators and are at the top of the food chain.)
The white shark is an apex predator (on top of the food chain) and as such, has very few predators. Killer whales and larger sharks pose the only natural threat to an adult white shark.
