Concept explainers
To explain:
The reason why the changing conditions challenge the survival of the organisms living in the estuaries experiencing both freshwater and saltwater conditions each day with the rising and falling of tides.
Concept introduction:
The species of plants, fishes and animals living in the saline conditions near the estuary adapt to the changing conditions of the climate. The plants have aerated roots for removing the salts and for the intake of gas for the

Which statement is supported by both the text and the excerpt above? All three penguin species, Chinstrap, Adelie, and Gentoo, live only on sea ice. The food supply for Adelie penguins includes both fish and krill in the Antarctic seas. Adelie penguins are dependent on the existence of sea ice for access to their food supply. Temperatures in the Antarctic have increased substantially in the last 60 years.arrow_forward

Aquifers beneath the state have been overpumped, and many wells have run dry. Agricultural production in the state is down, and farmers are clamoring for you to do something. Meanwhile, more water is needed for burgeoning urban populations in cities such as Los Angeles and San Francisco. What policies would you consider to restore California’s water supply? Would you try to take steps to increase supply, decrease demand, or both? Explain why you would choose such policies.arrow_forwardThinking Analytically Considering the fact that we have already found more than 20,000 deep-sea marine species and we have only explored a few percent of the deep ocean, how many total species do you think there may be in the deep sea?arrow_forward
