Biogeochemical Cycles

Front

What are the two main products of photosynthesis?

Back

Oxygen and glucose.

Front

What is the effect of burning fossil fuels on atmospheric CO2 levels?

Back

It leads to increased atmospheric CO2 concentrations.

Front

What are the two biological processes that form the basis of the carbon cycle?

Back

Cellular respiration and photosynthesis.

Front

What occurs during nitrogen fixation?

Back

Nitrogen gas turns into nitrogen compounds.

Front

What is a location where an element like carbon or nitrogen is stored called?

Back

A sink.

Front

Define biogeochemical cycles.

Back

Natural processes that recycle nutrients in various chemical forms from the environment to organisms and back to the environment.

Front

What role do decomposers play in biogeochemical cycles?

Back

They break down dead organic matter, returning nutrients to the soil.

Front

Explain the carbon cycle in brief.

Back

The carbon cycle involves the movement of carbon among the atmosphere, oceans, soil, and living organisms through processes like photosynthesis, respiration, and decomposition.

Front

What is the significance of the nitrogen cycle?

Back

It is essential for converting nitrogen gas from the atmosphere into forms usable by living organisms.

Front

What is a nutrient sink?

Back

A reservoir that stores nutrients, preventing them from being available for biological use.
