What is cellular respiration?

Back

Cellular respiration is the process by which cells use oxygen to break down glucose and produce energy (ATP) in the mitochondria.

What are the two processes used by autotrophs to make organic molecules?

Back

Photosynthesis and Chemosynthesis.

Front

What is glucose?

Back

Glucose is a type of sugar that provides easy-to-access energy (ATP) for living organisms.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight, water, and carbon dioxide to produce glucose and oxygen.

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which certain organisms create organic compounds using energy derived from chemical reactions, often in the absence of sunlight.

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What is an apex predator?

Back

An apex predator is a top predator in an ecosystem that has no natural enemies and plays a key role in maintaining the balance of the ecosystem.

Front

What is the role of mitochondria in cellular respiration?

Back

Mitochondria are the organelles where cellular respiration occurs, breaking down glucose to produce ATP.
