During the progression of each stage, the organisms in the food chain exert tons of energy. Most chains are broken down to four stages for that reason.
Think they do consist
food webs ... and because in marine ecosystems, there are phytoplankton as well. These microorggansims are not apparant in terrestrial food chains
Yes, all proteins are composed of one or more polypeptide chains, which are formed from amino acids. Proteins can be made up of a single polypeptide chain or multiple chains that interact with each other to form a functional protein molecule.
Food chains and food webs are different. This is because the webs have more relative food choices whereas the chains are limited.
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!
Organisms implemented in food chains or webs have generally claimed their place there, and don't have a difficult time surviving - which means survival appears to be definite for awhile.
Because the food web contains2 and more food chains
because a food chain is based on one certain thing in the ecosystem ....if the entire ecosystem was in it it would be a food web which is food chains from an ecosystem linked together
Energy is lost to the surroundings as the food chain goes from one level to the next, so there are fewer organisms at each level in the food chain. Eventually there would be no animals left for another animal to eat eg: grass----->rabbit----->fox----->? 100 10 1
more than 60
Aquatic food chains tend to be longer than land food chains because aquatic ecosystems often have more diverse and abundant species at each trophic level. The availability of different habitats and a greater variety of food sources in aquatic environments allows for more complex interactions and energy transfer among organisms, resulting in longer food chains. Additionally, the presence of phytoplankton, which form the base of many aquatic food chains, supports a larger number of higher trophic levels.
You can make an food web by joining 2 or more food Chains Together
