1. The right answer is C.

2. The right answer is A.

(Both answers has the same explanation, since it is approximately the same question).

Three forms of energy come into play in the functioning of an ecosystem:

* the electromagnetic radiation of short-wavelength (light),

* the electromagnetic radiation of long-wavelength (infrared: heat),

* chemical energy (in the form of organic molecules: sugars, etc.).

The conversion of light energy into chemical energy takes place in plants: it's photosynthesis.

Consider the following three populations of birds. Assume HW equilibrium. With these birds red coloring is recessive, while brow

Answer:

Red allele frequency will be highest in population II

Population III can undergo bottleneck effect

The frequency of the brown allele will least likely be altered in the population I

Explanation:

Population I -

Total population - $670$

Brown birds - $603$

Red birds - $67$

Population II

Total population - $100$

Brown birds - $90$

Red birds - $10$

Population III

Total population - $30$

Brown birds - $27$

Red birds - $3$

Frequency of red birds in population I

$\frac{67}{670} = 0.1$

Frequency of red birds in population II

$\frac{10}{90} = 0.11$

Frequency of red birds in population III

$\frac{3}{30} = 0.1$

Red allele frequency will be highest in population II and it will be equal to $\sqrt{0.11} = 0.33$ as compared to $0.31$ in case of population I and III
