1. What aspects are important for the success of biological pest control? 2. Why is this organism considered a pest? How has it affected other populations?
3. What do you think would have happened to the populations of their prey if this plague were not present? Explain your answer.
4. How the species proposed for the biological control of the pest could be a limiting factor for the pest population? Explain.
5. What other factors could limit the pest population and help control it?

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the correct answer is sex-linked recessive.

i just took the test

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.
