Fertilizer runoff causes an increase in the dissolved nutrients of the ecosystem shown in the food web below. This causes the number of phytoplankton to double. How will this most likely affect the other species in this ecosystem?

If excess fertilizer is mixed with the water,it causes algal bloom as the number of phytoplankton increases at the initial stage due to intake of large amount of nutrients that are obtained from the fertilizers.

Explanation:

The nutrients that are mainly found in fertilizer are nitrogen and phosphorus that mainly helps for growth and development of plants.Fertilizers that are applied in the agricultural field are rich in nutrients and minerals that enters into the water stream through runoff and disturbs aquatic environment by reducing the oxygen content in the water due to algal bloom,emits odour and gas in the air,release toxic substance that kills many aquatic organisms,decrease water quality,increase level of pathogen that creates life threatening diseases etc.

Answer from: Quest

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

According to the theory of punctuated equilibrium, at what rate does speciation occur? species change depending on the rate of natural selection. after periods of stasis, new species evolve relatively rapidly. species change slowly and eventually form new species. some species change quickly and others change slowly to balance the overall rate.
