Answer:
frequency of the blue (B) allele 
frequency of the red (R) allele 
The number of blue plants expected is 
The number of red plants expected is 
The anticipated number of violet plants is 
Calculated chi square value
Explanation:
Frequency of blue allele is
Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

Frequency of other allele

Chi Square test
See the attached file
The number of blue plants expected is 
The number of red plants expected is 
The anticipated number of violet plants is 
Calculated chi square value
Only 10% of the energy is transferred from one level to other,
so,
10% of 1,000J = 100 J
Which means 1000-100 = 900J of energy is used upon eating the snake.
(I’m not 100% sure about this answer though, but I think it will give u a good idea about energy transfer)
Transpiration is a vital process in plants through which plant are able to lower their body temperature and help to cool the plant
because due to high temperature plant can die and it also help to pump the water and minerals to leaves so it play a vital role
hope it helps
