Galveston Bay, an estuary in Southeast Texas, is shown below. The amount of salt in the water changes with the tides. Sometimes the water is mostly freshwater, and sometimes it is mixed with saltwater. Various plant species live in this environment and provide a habitat for other organisms.
To successfully live in an estuary, a plant species must have an adaptation that allows it to --
produce large amounts of food
absorb large amounts of water
store excess gases
filter excess salt
If the producer level of this food pyramid contained 6,500 calories how many calories would be transferred to the primary consumers?
650
65
61
65,000
Rabbits in most areas have a brown coat. The arctic hare has a bright white coat in winter.
How does the arctic hare's white color help it survive?

It helps the hare blend into its background.
It makes the hare appear larger to predators.
It helps the hare stay warm during the winter.
