Biology - Part 2

By Mr. Tomlinson

Photosynthesis / Cellular Respiration

• Photosynthesis- plants make their own food in the chloroplast.  Plants take in carbon dioxide (CO2), sunlight, & water (H2O) and produce glucose (C6H12O6) and oxygen (O2)

Multiple Choice

What do plants need to perform photosynthesis?

• Soil and Water

• Sunlight and Carbon Dioxide

• Water and Sunlight

• Oxygen and Sunlight

Multiple Choice

What is a product (what comes out) of photosynthesis?

• Carbon Dioxide

• Water

• Sunlight

• Oxygen

Photosynthesis / Cellular Respiration

• Cellular Respiration- When an organism takes in glucose (food) and it is broken down to be used as energy (ATP) for the body.

Photosynthesis / Cellular Respiration

• Your Digestive system breaks down food into small molecules called glucose (reactant).  Your respiratory system brings in O2 (reactants) and  releases CO2 (product).  Your circulatory system then takes the nutrients all around the body so all cells can perform cellular respiration (making energy [ATP] from food) in the mitochondria

Photosynthesis / Cellular Respiration

• Carbohydrates- breads, pastas- provide your body with the MOST usable form of energy

• Simple carbohydrates- provides your body with short lasting amounts of energy  Ex- fruits, vegetables, candy

• Complex carbohydrates- provides your body with long lasting amounts of energy Ex- breads & pasta

Photosynthesis / Cellular Respiration

• Protein- meat, beans, fish, chicken, eggs, nuts- builds and repairs muscle tissues.

• Lipids- a second source of energy

• Exercise allows your body to bring in more oxygen to break food down faster.

• Metabolism turns your food into energy
  

Multiple Choice

What kind of diet is the most important for us to be healthy?

• A high protein diet

• A high carbohydrate diet

• A balanced diet

• A diet with only vegetables

Limiting Factors

• Biotic factors= living (animals, plants, etc); Abiotic factors= non-living (sun, water, oxygen, etc)

• Limiting Factor- Biotic and Abiotic factors that slow/ stop a population's ability to grow.

• We can carry out investigations to determine limiting factors.

  
  

Multiple Choice

What are two abiotic parts of an ecosystem?

• Water and Air

• Water and animals

• Sunlight and Bacteria

• Animals and Fungi

Multiple Choice

What are two biotic parts of an ecosystem?

• Bacteria and Fungi

• Viruses and Sunlight

• Animals and Water

• Plants and soil

Limiting Factors

• Independent variable- what changes during the investigation.

• Dependent variable- what is being measured in an investigation.

• Constant (Controlled) variable- what stays the same throughout an investigation.

  
  

Relationships

• Niche= your role; Habitat= where you live 

• Autotroph/producer= makes its own food from sun

• Heterotroph/consumer= has to eat other things for energy

• Decomposer= breaks down dead & decaying organisms (bacteria; mushrooms)

  
  

Multiple Choice

Where does the goat get its energy from?

• The lion

• The snake

• The green plant

• The Jackal

Multiple Choice

What is the producer in this food web?

• The Green Plant

• The Rabbit

• The Snake

• The Lion

Multiple Choice

Who is the goat?

• Michael Jordan

• Lebron James

• Stephen Curry

• Kobe Bryant

Relationships

• 90% of energy is used at each level as you move up the energy pyramid.  Only 10% travels up.

  
  

Multiple Choice

Where is most of the energy found in an ecosystem?

• The carnivores

• The Primary Consumers

• The Producers

Energy / Matter Flow

• Carbon Cycle- goes to atmosphere through humans cellular respiration, decomposition, fossil fuels; carbon leaves atmosphere through plants (photosynthesis)

  
  

Multiple Choice

What helps take out CO2 from the atmosphere?

• People

• Cars

• Plants

• Factories

Multiple Choice

What causes lots of CO2 to enter the atmosphere?

• Plants

• Burning Fossil Fuels

• Trees

• Viruses
