Biomass is a way to describe the overall amount of living organisms in an area. using the figure below, choose the most likely reason for the decrease in biomass with an increase in depth and distance from the coast.

i included the answers with the picture.
i will give the brainiest though.

The correct answer would be "there is a reduction in the availability of nutrients away from the cost, which decreases primary production. Fewer producers and energy are available, leading to a decrease in biomass".

As we move in depth and distance from the coast the availability of sunlight decreases.  

Thus, the number of primary producers would decrease as they would be unable to perform photosynthesis.

Consequently, the number of nutrients available at that depth would be very less as compared to the coast.

Hence, the carrying capacity of the region would be less which ultimately decreases the biomass.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
