Construct a food chain with the following organisms-snake, hawk, rats and plants

Plants eaten by rats, rat eaten by snake and snake eaten by hawk.

Explanation:

Food chain may be defined as the sequential tropic levels of organism being eaten by other organisms. Food chains combine together in the environment to form food web.

Food chain starts with the producer (plants). Plants are eaten by the consumers present at first trophic level (rat). Second trophic level organisms eat the organism of first trophic level (snake). Third trophic level organism feeds on the second trophic level (hawk).

Thus, the food chain is plants eaten by rats, rat eaten by snake and snake eaten by hawk.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
