Unit 5- Energy and Life

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other food molecules to release energy.

Front

What is the primary molecule broken down during cellular respiration?

Back

Glucose.

Front

What is the role of producers in an ecosystem?

Back

Producers, like plants, convert light energy into chemical energy through photosynthesis, providing energy for other organisms.

Front

Which organism typically receives the least energy from a producer?

Back

Owl.

Front

What is the difference between a scientific theory and a scientific law?

Back

A theory explains why phenomena occur, while a law describes how they occur; for example, the theory of evolution and the law of gravity.

Front

What is the process of photosynthesis?

Back

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

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert food into usable energy (ATP) for cellular activities.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.
