Carbon Cycle

Higher concentrations of atmospheric carbon dioxide have led to increased biomass of many species, while biomass of coral reefs has decreased across the Great Barrier Reef in the hydrosphere.

Carbon is cycled through the atmosphere and hydrosphere by photosynthesis and cellular respiration, as shown in Figure 1.

Figure 2 shows ocean acidity. Ocean acidity is expressed as a measure of the concentration of hydrogen ions present in a liter of ocean water, with higher concentrations indicating a higher acidity.

Large male salmon have the highest rates of reproduction, yet only small male salmon are observed mating in one river.

In male salmon, reproductive success is a measure of advantageous traits and fitness in terms of natural selection. Table 1 shows data on percentages of successful matings by adult male salmon from five different regions in Alaska.

Even though bison generally require large, open areas with dense grass coverage to survive, they are sometimes observed living in small areas with sparse grass coverage.

Scientists studied four areas in Canada’s Banff National Park to determine habitat suitability for bison.

Peppered moths, Biston betularia, exhibit light- and dark-color variations. Over the years 1950–2000, changes to the trees inhabited by a population of peppered moths were observed.

In 1950, trees were primarily dark and covered in soot, as shown in Figure 1A. In 2000, trees in the same areas were primarily light and covered in lichen, as shown in 1B. Light- and dark-colored moths are shown on each tree.

Two marathon runners of similar athletic capabilities are running a marathon. Runner 1 ate a large meal of pasta the night before the race. Runner 2 ate tuna fish and salad. After 100 minutes of the race, one runner is farther ahead than the other runner.

Proteins, carbohydrates, and fats are dietary components that are the three basic nutritional building blocks of food. All of these can be converted to glucose, which is the body’s primary energy source.

Glucose can also be converted to glycogen, which is used as a source of energy while running when it is available, and stored in liver and muscle tissue.

Figure 1 shows the glycogen levels of the two runners and the distances they traveled during the first 100 minutes of the race.

Sharks and primates are both successful groups of animals. Both groups have been on Earth for millions of years, but they seem to form species at different rates.

Figure 1 shows an evolutionary tree with estimated origination times of six shark and primate species. Locations where lines split represent the moment in time when two modern species last shared a common ancestor.

A particular segment of DNA shared by all six species in a group was sequenced and analyzed. Figure 2 illustrates percent differences observed in sequences of this DNA segment relative to time that had passed between successive species in each group.

Research on a particular species of locust of the Yangtze Delta area of Southern China has revealed trends in their population as it changed over centuries, from 950 to 1900 CE.

The Oriental migratory locust (Locusta migratoria manilensis) is shown in Figure 1. This species becomes a major agricultural pest when its population reaches a high density.

Figure 1 is an illustration titled Figure 1: Oriental Migratory Locust. Shown is a picture of a large, green and brown locust on a person’s hand. It looks similar to a grasshopper. The head and top part of the thorax are green, while the underside is brown. The upper portion of the legs are green and the lower portion after the knee bend is brown. The wings, eyes, and antennae are brown.
