Which of the following is a renewable resource?

• Coal

• Solar energy

• Petroleum

• Natural gas

What role do abiotic factors play in an ecosystem?

• They represent all the living components of the ecosystem.

• They are the non-living chemical and physical parts of the environment that affect living organisms.

• They only include the weather conditions in an ecosystem.

• They are exclusively the water bodies found within an ecosystem.

Fossil records are important because they:

• Show the impact of human activities on ecosystems.

• Provide evidence of past life forms and the evolutionary history of life on Earth.

• Indicate the amount of natural resources available in the past.

• Demonstrate the types of renewable resources used by ancient civilizations.

What is the significance of geological time scales?

• They provide a detailed history of human evolution.

• They are used to measure the age of renewable resources.
