Choose two ecosystems, a marine and a terrestrial ecosystem. Create biomass and energy pyramids for each ecosystem. Then, study and compare each pyramid in terms of production efficiency and productivity. Focus on the following points when working on this activity.

The difference between the pyramids in each ecosystem.
The efficiency with which energy is transferred through all the trophic levels in the Energy and Biomass pyramids.
Explain how each level is a biomass to the next level in both pyramids.
Use the following keywords when researching: primary productivity, efficiency, production, biomass pyramids, and productivity pyramids.

your answer should be c) enjoy!

the answer would be   10%

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
