Answer 1

38. The right answer is D
39. The right answer is D
40. The right answer is D

Answer 2

The correct answers are (b) Neritic zone, (d) Deep sea, and (a) Biomagnification.

• The neritic zone is the region of shallow water (200 meters depth) higher than the ocean floor wherever light-weight penetrates to the ocean floor. thanks to the verdant provide of daylight and nutrients during this zone.
• Freshwater is outlined as having a coffee salt concentration — sometimes but I Chronicles. Plants and animals in fresh regions area unit adjusted to the low salt content and wouldn't be able to survive in areas of high salt concentration (i.e., ocean).
• Biomagnification is the accumulation of a chemical by an organism from water and food exposure that ends up in a degree that's larger than would have resulted from water exposure solely and so larger than expected from equilibrium.
