If a tt plant is crossed with a tt plant, what is the chance that a tt offspring will be produced? 75% 25% 50% 100%

the correct answer is 25%

T is the allele for tall plant, which is dominant trait. 't' is the allele for dwarf plant, which is a recessive trait.

Genotypes of the parent plants are- Tt and Tt. When they are crossed, there are 25% chances of producing tt offsprings. Refer the punnett square for this.

% of Offsprings with tt genotype =

                                                      =  25%

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
