Energy Flow in Organisms STEMscopes Concepts

Front

What is a reactant in a chemical reaction?

Back

A substance that takes part in and undergoes change during a reaction.

Front

Define a consumer in ecological terms.

Back

An organism that gets energy by eating another organism (heterotroph).

Front

What is cellular respiration?

Back

The process by which cells break down glucose into energy.

Front

What is the primary goal of cellular respiration?

Back

To make ATP (adenosine triphosphate).

Front

What gas is released during cellular respiration?

Back

Carbon dioxide.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various cellular activities.

Front

What is photosynthesis and how is it related to energy flow?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy (glucose), which is then used by consumers.

Front

Explain the difference between autotrophs and heterotrophs.

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs obtain energy by consuming other organisms.

Front

What is the relationship between cellular respiration and photosynthesis?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What is the significance of energy flow in ecosystems?

Back

Energy flow is crucial for maintaining the structure and function of ecosystems, as it determines how energy is transferred through food chains.
