-A wave is like water rippling in a pond.
Out of the following given choices;
(1) an increase in the number of clams
(2) a decrease in the number of water plants
(3) an increase in the number of crabs
(4) a decrease in the number of crayfish
The answer is D. Crayfish are are freshwater crustaceans resembling small
lobsters. Clams and crabs are found in marine waters. Most crayfish cannot
tolerate polluted water. Crayfish feed on animals and plants, either living or
decomposing, and detritus, therefore a decrease in small invertebrates in the river
would decrease their food source thence
consequently affect their numbers.
These mushrooms and other fungi will be classified as decomposers and they will obtain their nutrition by breaking down the body of organisms that have died. These organisms play a vital role in the cycling of nutrients in a food chain, since they convert the macromolecules present in dead organisms into smaller ones and release them back into the environment.
