Invasive Species

• Invasive species are non-native organisms that disrupt ecosystems.

• They often have no predators and outcompete native species.

• Can reduce biodiversity and alter habitats.

• Take resources from native species.

Biodiversity Importance

• High biodiversity increases ecosystem stability, resilience, and productivity.

• More species = more available ecological roles = greater survival chances for the community.

Multiple Choice

What is an invasive species?

• A native (naturally found) species which are added to an area. 
• A non-native (not naturally found) species added to an area. 
• A keystone species in an environment
• none of the above

Multiple Choice

Biodiversity, refers to

• the same species in a general location

• the number of different species in a given area

• the number of animal species in a given area

• the number of plant species in a given area

Multiple Choice

Invasive species don't harm native species that are beneficial to the environment.

• TRUE

• FALSE

Multiple Choice

Why do the populations of invasive species grow so quickly?

• Invasive Species are native to an area.

• Invasive species are prey to many animals.

• Invasive species have no natural predators.

• Invasive species keep the ecosystems in equilibrium.

ATP: The Energy Currency

• ATP = Adenosine Triphosphate

• Energy stored in chemical bonds

• The energy can be released when the 3rd phosphate group is released.

Cellular Respiration Equation

Cellular Respiration

• Provides the body with energy needed for life's cellular processes.

• The energy is produced in the form of ATP.

• All organisms require respiration to obtain energy.

• no oxygen needed

• produces much less ATP

Anerobic Respiration

• Requires oxygen

• Produces much more ATP

Aerobic Respiration

Types of Cellular Respiration

Multiple Choice

In Cellular Respiration, cells use energy available in food to create what energy-rich compound?

• ATP

• ADP

• glucose

• water

Multiple Choice

Energy is released from ATP when:

• ATP is exposed to sunlight

• a phosphate group is broken

• adenine bonds to ribose

• a phosphate group is added

Multiple Choice

______________ produces the most ATP.

• photosnthesis
• aerobic respiration
• anaerobic respiration
• glycolysis

Multiple Choice

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O
• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

Multiple Choice

What is cellular respiration?

• the breakdown of glucose  to release ATP
• the breakdown of glucose to release NADH
• the breakdown of glucose to release FADH
• the breakdown of glucose to release carbon

Multiple Choice

The mitochondria is responsible for ...

• photosynthesis
• anaerobic respiration
• aerobic respiration
• fermentation

Multiple Choice

Please select who performs cellular respiration: 

• Animals 
• Both animals and plants 
• plants 

Photosynthesis

• Process where plants make their own food

• Occurs in chloroplasts

• Converts light energy to chemical energy

Photosynthesis Equation

Photosynthesis and CR

• The inputs to Cellular Respiration are the outputs of Photosynthesis, and vice versa.

• Both plants and animals do cellular respiration.

Multiple Choice

What are the products of photosynthesis?

• Carbon Dioxide & Water
• Glucose & Oxygen
• Water & Oxygen
• Glucose & Carbon Dioxide

Multiple Choice

What structure within a plant cell does photosynthesis?

• Sap vacuole
• Cytoplasm
• Chloroplasts
• Chlorophyll

Multiple Choice

What are the inputs of photosynthesis?

• Glucose & Oxygen

• Glucose & Carbon Dioxide

• Light & Chlorophyll

• Carbon Dioxide, Water, & Light.

Multiple Choice

Where do plants get the energy for photosynthesis to take place?

• nutrients in the soil

• the sun

• chlorophyll

• bee pollination

Multiple Choice

Which gas is removed from the atmosphere during photosynthesis?

• hydrogen
• oxygen
• nitrogen
• carbon dioxide

Multiple Choice

In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.
• Cellular respiration produces oxygen, while photosynthesis uses oxygen.
• Photosynthesis releases energy, while cellular respiration stores energy.
• Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

Multiple Choice

Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + 6H₂O --> 6O₂ + C₆H₁₂O₆
• 6CO₂ + C₆H₁₂O₆ + 6H₂O --> O₂ 
• 6O₂ + 6H₂O --> 6CO₂ + C₆H₁₂O₆
• C₆H₁₂O₆ + 6O₂ ---> 6H₂O + 6CO₂ 

Multiple Choice

How can photosynthesis be related to cellular respiration?

• What's produced by one is needed for the other
• They both produce the same products
• They both have the same reactants (need the same things)
• These 2 processes have nothing in common

Multiple Choice

Why is photosynthesis important?

• creates oxygen for animals to breath
• creates energy for heterotrophs to use
• creates food for plants to use
• all of these are correct
