What happens to energy in a food pyramid as you move up the levels?

Back

Energy is lost to the environment at each level, so less mass can be supported at each higher level.

What is the relationship between carbon dioxide levels and Earth's surface temperatures?

Back

Higher carbon dioxide levels mean more heat is retained in Earth's atmosphere.

Front

Which process decreases the amount of carbon dioxide in the atmosphere?

Back

Photosynthesis.

A genetic condition that manifests only when an individual has two copies of the recessive allele.

Front

What is a food pyramid?

Back

A graphical representation of the food chain, showing the energy flow and biomass at each trophic level.

Front

Explain the significance of carbon dioxide in the atmosphere.

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, affecting global temperatures.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of decomposition in the carbon cycle?

Back

Decomposition breaks down organic matter, releasing carbon dioxide back into the atmosphere.
