Carbon Cycle - Applying knowledge

A worksheet aimed at A-Level Biology students that requires students to read a passage of text, study diagrams and answer questions that require application of knowledge on the Carbon Cycle. The stimulus material is in the context of space science research and mapping of the Earth's oceans. Phytoplankton are a major carbon sink and their numbers are declining, possibly as a result of global warming. This worksheet considers the implications of this change.

Keywords: Phytoplankton, Carbon cycle, space, satellite, envisat, sink. oceans, greenhouse, global warming
