Ch. 4 Test Review: Chemical Compounds in Cells

Front

What is an abiotic factor?

Back

An abiotic factor is a non-living component of an ecosystem, such as water, sunlight, and minerals.

Front

True or False: Water is an abiotic factor.

Back

True

Front

What is the role of sunlight in ecosystems?

Back

Sunlight provides energy for producers (plants) through photosynthesis, which is then transferred to consumers (animals) when they eat the producers.

Front

True or False: Energy from sunlight ultimately becomes energy for animals.

Back

True: it provides energy for producers and they are eaten by primary consumers.

Front

In the chemical reaction 6CO2 + 6H2O → C6H12O6 + 6O2, what are the reactants?

Back

The reactants are 6CO2 + 6H2O.

Front

What are the products in the reaction 6CO2 + 6H2O → C6H12O6 + 6O2?

Back

The products are C6H12O6 + 6O2.

Front

What are organic compounds?

Back

Organic compounds are molecules that contain carbon and are essential for life, including carbohydrates, lipids, proteins, and nucleic acids.

Front

What are the four main types of organic compounds needed by living things?

Back

Carbohydrates, lipids, proteins, and nucleic acids.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the significance of carbon in organic compounds?

Back

Carbon is the backbone of organic compounds, allowing for the formation of complex molecules essential for life.
