<span>Insects are found in almost all ecosystems on Earth, with the rarity being oceans. While some species, such as coconut crabs, sand hoppers, woodlice and pill bugs dwell on land, crustaceans are generally found in water — and usually oceanic — regions. Adapting to their habitat, many insect species evolved wings — two pairs for most and one pair for others. A tracheal system is also present for breathing. Crustaceans, on the other hand, breathe using gill-like mechanisms.</span>

Explanation:
The ischium bone forms the superior part of the pelvic girdle.
<h3>What is the structure of the pelvic girdle?</h3>
In the bottom region of the trunk, there is a bony structure known as the pelvic girdle that resembles a ring. It joins the lower limbs to the axial skeleton. There are two types of pelvises: the bigger pelvic and the lesser pelvis.
The pelvis is made up of two paired hipbones that are joined at the pubic symphysis in front and by the sacrum in back. Each hipbone is composed of three bones: the blade-shaped ilium above and to either side, which determines the hips' width; the ischium below, on which the weight is placed when sitting; and the pubis in front. Early in maturity, all three come together at a triangle suture in the acetabulum, the cup-shaped socket that connects to the head of the femur to create the hip joint.

Answer:
18 ATP.
Explanation:
Total 18 ATP are produced because 9 FADH2 are converted into 9 ATP molecules and the earlier 9 ATP molecules are already present in the first b-oxidation process. The first Krebs cycle produces 27 NADH, 9 FADH2 and 9 ATP while on the other hand, the second Krebs cycle produces 9 ATP molecules from 9 FADH2 so total it produces 18 ATP molecules.
