Chapter 54, Problem 9TY
Summary Introduction
Introduction: The weather pattern prevailing in a particular region is known as its climate. Latitudinal variations in the solar radiations arriving on Earth cause temperature differences across the planet. Variations in temperatures across regions decide the type of biological species inhabiting them. The major types of habitats that are differentiated on the basis of different types of flora and fauna inhabiting them are known as biomes. Biomes are majorly of terrestrial and aquatic types.

- The figure above shows main abiotic and biotic factors influencing the physiology and behavior of fish larvae in estuaries. The more important the factors are for the larvae, the thicker the lines. Suppose changes from question 1 take place. Draw a new figure and redefine the thickness of the lines and new factor interactions. This is from question 1 : A proposal is made to deepen the entrance and main channel of an estuary. What do you suppose will happen to the salt marshes that surround the channel? What do you predict will happen to the productivity of the estuary? Deeper channels would probably change the mixing of the fresh and saltwater and lead to increased salinity and changes in the salt wedges in the channel. This would probably negatively impact the plants on the edges of the channel, as they would have to deal with higher salt levels than they are adapted to. The strain that would be put on the plants (like cordgrasses) in the marshes, would most likely lead to a…arrow_forwardMost of the fresh water in the world is used fora. drinking. b. supporting industry.c. irrigating crops.d. cooking.e. bathing.arrow_forwardWhich of the statements about freshwater distribution and use is correct?a.
