7. There is evidence that the increasing carbon dioxide levels in the atmosphere are causing oceans to become more acidic. Ocean acidification may negatively
impact species of phytoplankton, which are microscopic photosynthetic
organisms that live in surface waters. Explain how the carbon cycle might be
affected if phytoplankton populations were to decrease.

Whats one way that rocks do not follow the typical rock cycle pathway?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 8 options: the cold balloon expands and rises. the warm balloon shrinks and sinks. the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the warm balloon expands and rises. the cold balloon shrinks and sinks.

Amarine ecologist has constructed the conceptual model shown in the diagram. what predictions can be made from using this model? where the tertiary consumers get their energy how often primary producers are able to reproduce when bacteria and fungi initiate the process of decomposition whether other secondary consumers are present
