Biogeochemical Cycles Quiz

During a science class, Luna and Grace were discussing the biogeochemical cycle. What is the biogeochemical cycle?

• The cycling of chemical elements through the living and nonliving parts of an ecosystem

• The process by which precipitation is gathered into a body of water

• The process that allows green plants to make sugars from sunlight, water, and carbon dioxide

• The process in cells by which oxygen and glucose are used to produce energy and carbon dioxide

During a field trip, Ava noticed water flowing over the surface of the soil after a heavy rain. What is this process called?

• Collection- The process by which precipitation is gathered into a body of water

• Runoff- The precipitation that flows over the surface of soil

• Photosynthesis- The process that allows green plants to make sugars from sunlight, water, and carbon dioxide

• Fossil Fuels- A source of energy formed from dead plants and animals

Nora is learning about how plants make their own food. What is photosynthesis?

• The process that allows green plants to make sugars from sunlight, water, and carbon dioxide

• The process in cells by which oxygen and glucose are used to produce energy and carbon dioxide

• The cycling of chemical elements through the living and nonliving parts of an ecosystem

• The precipitation that flows over the surface of soil

James is learning about cellular processes in his biology class. What is cellular respiration?

• The process in cells by which oxygen and glucose are used to produce energy and carbon dioxide

What is nitrogen fixation?

• The conversion of nitrogen in the atmosphere to a form that can be used by plants

• The process that releases nitrogen from the soil back into the atmosphere

• A plant that hosts nitrogen-fixing bacteria in nodules on its roots

• A swelling on a plant root that contains nitrogen-fixing bacteria
