Left Column (Questions 1 - 5)

Question 1

Oysters, crabs, and wading birds are associated with coastal, brackish water habitats. A salt marsh is a coastal wetland with such conditions, while deserts, grasslands, and forests do not support these species.

Grasslands are dryish, grass - dominated. Frogs need water - rich environments (ponds, streams) to breed and live. Prairie dogs, lions, and bison are adapted to grassland conditions.

Grasslands have lots of grasses (producers). Large herbivores like bison eat grass. Option A says there's an abundance of grasses to eat, which explains why bison live there. Option B is about salty water (not grassland), C about tall trees (grasslands have few trees), D says too dry for plants (false, grasslands have grasses).

Answer:

B. Salt marsh
