Carbon Cycling

100

This sugar is the main source of energy for heterotrophs

Glucose

200

This is one way for carbon to leave the atmosphere

Photosynthesis, dissolution

300

These are two ways carbon can be ADDED to the atmosphere.

Burning fossil fuels, deforestation, respiration, decomposition

400

Increased CO₂ in the atmosphere leads to an increase in this abiotic factor.

Temperature

500

This is how it is possible for CO₂ levels in the atmosphere to increase but the amount of carbon in the ecosystem to remain the same.

Law of Conservation of Mass, Matter cannot be created or destroyed, Matter cycles throughout the ecosystem and changes form.

Photosyn-this Or That

100

This or that: Plants take in sunlight or ATP to make sugars

Sunlight

200

This or that: Photosynthesis requires carbon dioxide or oxygen

Carbon dioxide

300

This or that: The main goal of photosynthesis is to make sugar or oxygen

Sugar

400

This or that: A byproduct of respiration is carbon dioxide or oxygen

Carbon Dioxide

500

This or that: Photosynthesis occurs in the chloroplast or mitochondria

Chloroplast

You Are What You Eat

100

These organisms create their own food using sunlight

Photoautotrophs

200

These organisms have to eat other organisms to obtain energy

Heterotrophs

300

I perform both photosynthesis and cellular respiration

Autotroph

400

I eat plants, so I am a this

Heterotroph or Herbivore

500

This organism does not have access to sunlight, so they use compounds like sulfuric acid to make alternative sugars

Chemoautotroph

Oxygen Optional

100

Anaerobic respiration occurs without…

Oxygen

200

Yoga, swimming, or jogging are examples of using aerobic or anaerobic respiration

Aerobic

300

In aerobic respiration, organisms take in these two reactants

Glucose and oxygen

400

In animals, this byproduct of anaerobic respiration builds up and causes muscle soreness and fatigue

Lactic Acid

500

When plants perform anaerobic respiration, we call it this process, mainly named for the byproduct they produce

Alcohol fermentation

Elemental

100

This element is the central element in all organic compounds

Carbon

200

These two elements are cycled through processes such as condensation, evaporation, and transpiration

Hydrogen and Oxygen (H₂O)

300

We need this element to build amino acids, but it is non usable in gas form. Don’t worry bacteria can help “fix” it

Nitrogen

400

This element can be added into its cycle through weathering and erosion

Phosphorus

500

Nucleic Acids are composed of these elements (list all)

carbon, hydrogen, oxygen, nitrogen, and phosphorus
