Decomposition and Hydrothermal Vent Communities

Front

Decomposition and carbon dioxide.

Back

Decomposition reduces the amount of carbon dioxide released into the atmosphere.

Front

Decomposition and starch molecules.

Back

Decomposition produces starch molecules used by other organisms for food.

Front

Importance of decomposition in the carbon cycle.

Back

Decomposition reduces carbon dioxide and recycles nutrients in ecosystems.

Front

Cyanobacteria blooms can lead to changes in population sizes of waterfleas, zebra mussels, and mollusks.

Back

Nitrogen fixation by cyanobacteria is essential for ecosystem health.

Front

The graph shows the level of atmospheric carbon dioxide in the Northern Hemisphere over the course of 2017.

Back

More photosynthesis occurs during the spring and summer, reducing atmospheric carbon dioxide levels.

Front

Effect of Nitrogen on Marine Life

Back

Nitrogen leaching from island soils spurs marine life growth, making reefs more abundant around rat-free islands.

Front

Flow of Nitrogen in Chagos Islands

Back

Ocean fish → seabirds → soil → plants

Front

Seabirds' Nutrient Transport

Back

Seabirds transport nutrients from ocean fish to island soils.

Front

Rats and Ecosystem Disruption

Back

Rats disrupt the ecosystem by reducing seabird populations and nutrient flow.
