Answer:

Producer means an organism that can produce it's own food. Plants are prime examples of producers

Primary Consumer means organisms that primarily eat plants and have low energy levels. Squirrels fit into that category. They're almost always herbivores.

Secondary Consumers eat both plants and animals in the Primary Consumer. Crows are technically secondary consumers but I've never seen one eat a squirrel before.

Tertiary Consumers are predators that have the highest energy levels and are at the top of the food chain. Coyotes eat both squirrels and crows.

Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Chi Square test

See the attached file
