Answer:
ecosystem
Explanation:
The level of organization shown in the example is "ecosystem" because the example represnts interaction between two different population with acorns on the land.
Ecosystem is defined as the interaction of groups of organisms in biological domain with abiotic enviornment.

Every adenine base is paired to a thymine base, so there have to 500 thymine bases to match up with the adenine bases.
Answer:
The answer is 3:2
Explanation:
A cubic cell has 6 sides
= 6 side²
= 6 × 4²
= 6 × 16
= 96 mm²
Volume of a cubic cell
= side³
= 4³
= 64 mm³
The ratio of the surface area to volume of imaginary cubic cell is therefore:
= 96/64
= 3/2
= 3:2
