CD Unit 3 Biology Review

Front

What happens if our emission rates of greenhouse gases do not stop climbing?

Back

Glaciers and polar ice caps will melt.

Front

Where can carbon atoms be stored?

Back

Carbon atoms can be found in living things, fossil fuels, and rocks.

Front

What is the effect of an increase in producers in an ecosystem?

Back

There would be more organisms at each trophic level.

Front

What is an effective way to decrease emissions of carbon dioxide?

Back

Using solar energy when available.

Front

If the biomass of the producers is 3,900 kg, what is the expected biomass of the secondary consumer?

Back

39 kg.

Front

Define greenhouse gases.

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases.

Front

What role do producers play in an ecosystem?

Back

Producers convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.

Front

What is biomass?

Back

Biomass is the total mass of living matter in a given area or volume.

Front

Explain the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms.
