Food chains and food webs describe the feeding relationships between species in a biotic community In other words, they show the transfer of material and energy from one species to another within an ecosystem. As usually put, an organism is connected to another organism for which it is a source of food energy and material by an arrow representing the direction of biomass transfer.
Organisms are grouped into trophic levels based on how many links they are removed from the primary producers. Primary producers, or autotrophs, are species capable of producing complex organic substances (essentially "food") from an energy source and inorganic materials. These organisms are typically photosynthetic plants, bacteria or algae, but in rare cases, like those organisms forming the base of deep-sea vent food webs, can be chemotrophic. All organisms that eat the autotrophs are called heterotrophs. They get their energy by eating the producers.
A food chain describes a single pathway that energy and nutrients may follow in an ecosystem. There is one organism per trophic level, and trophic levels are therefore easily defined. They usually start with a primary producer and end with a top predator.
Here is an example of five organisms in a single food chain: phytoplankton to copepod to fish to squid to seal to orca..
Well, there's more than 3 levels in the food chain, but to your question 1)producer 2)consumer 3)secondary consumer
There's more than 3. Producers, Primary Consumers, Secondary Consumers, Tertiary Consumers, and Quaternaries.
3-organism example:Wheat grows on the ground. A field mouse eats the wheat. A snake eats the mouse.
If it's consuming anything, it's most likely an organism. Grass, squirrel, deer.
What type of organism make up the base,middle,and top of the food web
Plants > herbivores > carnivores
decomposor
poop
Completely unjoin all three links of one section of chain and use those three links to link together the remaining chain links.
It depends on the length of the chain and the size of the links. A chain as a unit of measure is 66 feet long. Four rods equals one chain. A link is 0.04 rod, or 7.92 inches. There are 100 links in a chain.
Tell me
The number of links in a food chain is ultimately limited by the amount of energy in the producers of the particular ecosystem.
the monarch butterfly is one of the first links of the food chain.

There are colored links in three places on the chain. It helps to clean the chain with brake cleaner to find them.There are colored links in three places on the chain. It helps to clean the chain with brake cleaner to find them.
There cannot be too many links in a food chain. Food chains always begin with a plant and end with an animal. If there are more than 4 or 5 links in the chain , there will not be enough food for the animals at the end of the chain.

Yes. See the Related Links for more information.
because of the amount of energy lost between trophic levels
