Question

1. freshwater and seawater mix in a(n) a) estuary. b) benthic zone. c) limnetic zone. d) littoral zone. 9) the kind of vegetation in a tropical rain forest is generally determined by a) rainfall. b) nitrogen in the soil. c) minerals in the soil. d) light. 10) a photograph of a victorian trophy - room shows the heads of many animals that grazed. all were hunted within a days walk of a single house. the house was probably located in a) tropical rainforest. b) chaparral. c) savanna. d) desert. which of the following options correctly pairs a biome and its characteristics? a) temperate broadleaf forest=mild winters, moderate rainfall. b) chaparral=mild, rainy winters

Explanation:

1. Estuaries are regions where freshwater from rivers and streams mixes with seawater. The benthic zone is the bottom - most zone of a water body, the limnetic zone is the open water area of a lake or pond, and the littoral zone is the near - shore area of a water body.
2. In a tropical rainforest, light is the most limiting factor for vegetation as the dense canopy blocks much of the sunlight from reaching the lower layers. Rainfall is abundant, and soil nutrients like nitrogen and minerals are recycled quickly.
3. Savannas have large grazing animals and were historically areas where hunting of such animals could occur within a day's walk. Tropical rainforests have dense vegetation and different types of animals, chaparral has shrubs and is fire - prone, and deserts have sparse animal life.

Answer:

1. A. estuary
2. D. light
3. savanna
