The ultimate source of energy for all ecosystems is the Sun. Only producers can convert solar energy into food energy. Therefore, all other organisms depend on producers for their energy needs.

Food Chains vs. Food Webs

Assignment.....

  1. Your first paragraph should include the definition of a food chain and an example of a food chain with at least 5 organisms.  Make sure you name the organism and explain who eats who in the chain. (7.5 Points)

A definition of a food chain is somewhat a linear sequence of links in a food web starting from a Trophic species that eats no other species in the web. And ends at a Trophic species that is eaten by no other species in the web.

And example of a food chain is:Algae get eaten by the small fish the small fish gets eaten by the large fish the large fish get eaten by the Sea lion the sea lion get eaten by the shark the shark get eaten by the bacteria.

The definition of a food web is The food web is a simplified illustration of the various methods of feeding that links an ecosystem into a unified system of exchange. There are different kinds of feeding relations that can be roughly divided into herbivory, carnivory, scavenging and parasitism.

And example of the food web is: Green plant get eaten by a mouse the mouse get eaten by the rabbit and the rabbit get eaten by the Jackal the Jackal get eaten by the Wild cat the wild cat get eaten by the lion

A food chain is a dipiction of a simple, one-webbed line of natural process within certain organisms. An example of a food chain is: The plants are eaten by the grasshopper, the grasshopper is eaten by the frog, the frog is eaten by the snake, and the snake is eaten by the owl.
A food web is a dipiction of the natural process in the entire ecosystem. An example of a food web is: The plant is eaten by the grapphopper, the frog and the squirrel. The frog and squirrel are eaten by the snale and fox. The snake is eaten by the owl.

A food chain is a list of animals that eat each other. These are five animals , The grass is eaten by cricket and frog eat cricket and snake eats frog and snake is eaten by a owl.



A food web is when more the on animal eats animal, Fox eats a rabbit and bird the bird eats the worm and ants.

A definition of a food chain can be a sequence of organisms in an ecosystem, in which each species is the food of the next member of the chain. My example is going to be on the ocean, A small fish eats plankton, A bigger fish eats that fish A crab eats that fish and a seagull eats the crab.
A combination of food chains that integrate to form a network that makes the food web my food chain plus Mr. Reese's plus Anthonys chain makes a web.

A food chain describes the feeding relationships and energy flow between species within an ecosystem. An example of a food chain is the algae is eating by the minnow the minnow is eating by the salmon and the salmon is eating by the bear.

A food web is a group of interconnected food chains. An example is phytoplankton is eating by the krill the krill is eating by birds,penguins, and leopard seal the leopard seal is eating by the smaller toothed whales and the smaller toothed whales are eating by the baleen whale.

A definition of a food chain is when the shrimp eats the algae the arctic cod fish eats the shrimp the ringed seal eats the arctic fish and the polar bear eats the ringed seal.

A food chain is a line of organisms eaten by other organisms.An example of a food chain is algae eaten by a minnow,a minnow eaten by salmon,a salmon eaten by a bear,a bear (as carrion) eaten by vultures.

A food web is a group of multiple food chains in an area.An example of a food web is a plant eaten by a field mouse which is eaten by a python and a fox,that plant is also eaten by a grasshopper which is eaten by a frog,a bushel of berries eaten by rabbits and chipmunks which is killed by pythons and foxes.

That is the conclusion on food chains and food webs.

A food chain is a graph showing what its what in a specific area for example rabbit eats grass, fox eats rabbit, bear eats fox, crocodile eats bear, anaconda eats crock.

A food chain means the feeding relationships and energy flow between species within an ecosystem . An example of a food chain is bear , fox ,rabbit , bird and worm . The bear eats the fox , fox eats the rabbit , rabbit eats the bird , and the bird eats the worm .

A food web is a group of interconnected food chains . An example is krill , fish , penguins , leopard seal , and smaller toothed whales . The fish eats the krill , the penguins eat the fish , leopard seal eats the penguins , and the smaller toothed whale eats the leopard seal .

The definition of a food chain is a food relationship of an animal. The first animal is a piece of grass. Then a rabbit will eat it. Then the fox eat the rabbit. Then the bear can eat the fox and then the vulture can eat the bear.
The definition between the food web is the web that shows the animals who they eat who. Like for example a deer eats plants then a wolf will eat the deer. Then the bear will eat the wolf. Then the vulture will eat the bear.

A food chain is the order in which things are eaten. The Wildebeest eats grass. The the Lion then eats the Wildebeest. The Lion is at the top of the food chain. A food web are different animals eating different things and the things they eat.

A food chain describes the feeding relationships and energy flow between species within an ecosystem.An example of the food chain would be:algae,minnow,salmon,and a bear.This is an example to the the food chain because the minnow would eat the algae and the salmon would eat the minnow and the bear would eat the salmon.

A food web is a group of interconected food chains.An example of a food web would be:berries,mouse,snake,hawk,fox,,rabbit.

This is an example of a food web because the mouse would eat the berries and the the snake would eat the mouse then the hawk would eat the snake or the mouse or it could eat the fox or rabbit.

A food chain describes the feeding relationships and energy flow between species within ecosystem.An example of the food chain is, Algae is the producer and it gets their energy from sun light then the Minnow is the primary consumer and they eat the algae to get it's energy and then the salmon comes and eats the Minnow and the bear catches the salmon and eat it to get his energy.

A food web is a group of interconnected food chains.An example of a food web is the plankton gets eatten by the krill which gets eatten by the leoperd seal and then gets eatten by the smaller tooth whales.

A food chain is made up of different types of animals that live in the same niche.The plant soaks up energy from the sun,a moose eat the plant,snake eats the moose, hawk eats the snake.

A food web has every organism in the ecosystem,unlike a food chain every organism is a part of it.The sun gives energy to the plant in the ocean,the bird eats the fish,frog eats the bird,coyote eats the frog,people shoot the coyote.

A food chain is A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and in turn is preyed upon by a higher member a example is ,A squirrel eats a berry, a bird eats the squirrel, a turkey eats the bird, and a human eats the turkey.

A food web is a interlocking system of food chains containing many more animals showing who eats who.
for example...

grass absorbs sun light, a mouse eats grass, a raccoon eats grass and the mouse, than a fox eats a raccoon and the mouse,which is then eaten by the wolf which is the top of the food web.
