diversity in the ecosystem happens as a result of evolutionary pressure
Tundras, Rainforests, coral reefs and deciduous forests all are formed as a result of evolutionary pressures. Even seemingly small evolutionary interactions can have large impacts on the diversity of the ecosystems throughout the world.

Answer:
Son's age is 25.
Step-by-step explanation:
Let the Father's age be 2x.
Let the son's age be x.
Five years ago:
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then:
2x - 5/x-5 = 9/4
⇒ 4(2x - 5) = 9(x - 5)
⇒ 8x - 20 = 9x - 45
⇒ -20 + 45 = 9x - 8x
⇒ 25 = x
∴ x = 25
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50 years

Step-by-step explanation:
Answer:
300 in.³
Step-by-step explanation:
We find the volume of 1 prism and multiply it by 2.
V = BH
where V = volume of prism, B = area of the base of the prism, H = height of the prism
V = ½bh × H
V = ½(5 in.)(6 in.) × 10 in.
V = 150 in.³
That is the volume of one triangular prism. Now we multiply it by 2.
volume = 2 × 150 in.³ = 300 in.³
