Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where life exists, including land, water, and the atmosphere.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms break down carbon-based molecules to produce energy, releasing carbon dioxide as a byproduct.

Front

What is a limiting nutrient?

Back

A limiting nutrient is a nutrient that is in short supply and restricts the growth of organisms in an ecosystem.

Front

What is the carbon cycle?

Back

The carbon cycle is the series of processes by which carbon compounds are interconverted in the environment, involving processes like photosynthesis, respiration, and decomposition.

Front

What is the role of phosphorus in ecosystems?

Back

Phosphorus is an essential nutrient for plants and animals, playing a key role in energy transfer and the formation of DNA and RNA.

Front

What is the geosphere?

Back

The geosphere refers to the solid parts of the Earth, including rocks, minerals, and the landforms.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as water vapor through pores in leaves.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water is converted into water vapor, often due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air is changed back into liquid water, often forming clouds.
