What is a potential effect on a food web if a activity of decomposers was inhibited? A)Overall water availability would decrease across all levels of the food web.

B)The organism in the food web would have greater availability of nutrients.

C)The flow of energy through the food web would stop, leading to the death of each organism.

D)The organism in the food web would have a diminished availability of nutrients.

D)The organism in the food web would have a diminished availability of nutrients.

Explanation:

Decomposers decomposes the dead plant or animal  and provide nutrients and energy in the organic material. The nutrients is then mix with soil and utilize by plants to grow.

If a activity of decomposers was inhibited in a food web, plants will be unable to get nutrient and plats growth will diminish. As plants are primary producers the availability of nutrients  for other animals will also diminish.

Hence, the correct option is D)The organism in the food web would have a diminished availability of nutrients.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
