What example best fits the Law of Conservation of Matter in Biology?

• A sunflower that absorbs carbon dioxide from the air to be converted to sugar (glucose).

• A oak tree that absorbs light energy to be stored in sugar (glucose).

• Heat from the body after running.

• Light coming from the sun.

What is an heterotroph? 

• An organism that can produce its own form of energy (via the Sun) 
• An organism that consumes only plants for energy
• Various organisms that consume other organisms for energy
• An organism that decomposes other organisms 

What are the products in cellular respiration?

• water and carbon dioxide
• water and glucose
• carbon dioxide and oxygen
• glucose and oxygen

What is the purpose of cellular respiration?

• to break down food

• to create energy in the body

• there is none; it's a waste of time

• to release energy from food

This reaction releases chemical energy from sugars and carbon dioxide molecules when oxygen is present.

• Chemosynthesis

• Cellular respiration

• Photosynthesis

• Detritus

What happens to matter after it leaves decomposers?

• It is used in the cellular respiration reaction.

• It is consumed by autotrophs.

• Matter is converted into soil, air, and water.

• Matter is converted into heat.
