What is the waste product of photosynthesis released to the environment?

Back

Oxygen is the waste product of photosynthesis that is released into the environment.

Front

What does a positive feedback loop do?

Back

A positive feedback loop increases the stimulus, leading to an amplified response.

Front

What is the primary function of cellular respiration?

Back

The primary function of cellular respiration is to convert glucose into ATP, which provides energy for cellular activities.

Front

What are the monomers of lipids?

Back

Glycerol and fatty acids are the monomers that make up lipids.

Front

Which organism has the most amount of energy in an ecosystem?

Back

Grass has the most amount of energy in an ecosystem, as it is a primary producer.

Front

What is the role of ATP in cells?

Back

ATP (adenosine triphosphate) serves as the main energy currency of the cell, providing energy for various cellular processes.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP, using oxygen and releasing carbon dioxide and water.

Front

What are the two main types of feedback mechanisms in biological systems?

Back

The two main types of feedback mechanisms are positive feedback and negative feedback.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food (e.g., plants), while heterotrophs are organisms that consume other organisms for energy (e.g., animals).
