Answer 1

22. The correct answer is c. Bioaccumulation. Bioaccumulation refers to the increase in the amount of chemicals within an organism over time. This occurs when an organism absorbs a substance at a rate faster than it can metabolize or excrete it, leading to a buildup of the substance in its body.23. The correct answer is b. It releases the water in increments which slows the water down therefore slowing erosion. Wetlands act as natural buffers during heavy rainfall or flooding events. They absorb excess water and release it gradually, which helps to slow down the flow of water and reduce erosion. This process is beneficial as it helps to prevent flooding in nearby areas and maintain the natural balance of the ecosystem.24. The correct answer is b. Sediment. Dirt, sand, and sile are classified as sediment pollution. Sediment pollution occurs when excessive amounts of sediment, such as soil or sand, enter water bodies. This can have negative impacts on aquatic ecosystems, including reduced light penetration, smothering of aquatic habitats, and increased turbidity.25. The correct answer is d. Aphotic zone. The aphotic zone is the region of a body of water, such as an ocean, where no light penetrates and photosynthesis cannot occur. It is the deepest part of the ocean, located below the photic zone where sunlight can still be detected. In the aphotic zone, the lack of light makes it impossible for photosynthetic organisms to survive, resulting in a unique and distinct ecosystem adapted to the darkness.
