What are decomposers?
Break down dead material for nutrients
What process do plants use to make food?
Energy captured by producers is passed to consumers through food
What does the cell membrane do?
Controls what enters and leaves the cell
What is the difference between dominant and recessive traits?
Dominant traits show with one allele; recessive need two
What is the main function of the respiratory system?
Takes in oxygen and removes carbon dioxide
What is a food chain?
Sequence showing who eats whom
What gas do plants take in during photosynthesis?
Products of one are reactants of the other
How are plant and animal cells different?
Plant cells have a cell wall and chloroplasts, animal cells do not
How can a mutation affect an organism?
May change the protein and affect traits
How do the circulatory and respiratory systems work together?
Work together to deliver oxygen and remove CO₂
How do organisms compete for resources?
Compete for food, water, space, or mates
Compare photosynthesis and respiration.
Photosynthesis makes glucose; respiration breaks it down
Why is the nucleus called the control center of the cell?
It Stores DNA and controls cell activities
Predict the outcome of crossing two heterozygous parents (Tt x Tt).

What would happen if the nervous system stopped working?
Body wouldn’t respond to stimuli or control movements
What happens if an invasive species is introduced?
May outcompete native species and disrupt ecosystem
How do photosynthesis and respiration form a cycle?
Products of one are reactants of the other
Explain the process of cell division (mitosis).
Cell divides to produce two identical daughter cells
Explain how traits are inherited using a pedigree chart.
Shows how traits are passed across generations
Design a plan showing how body systems respond to exercise
Heart rate increases, lungs work harder, muscles use more oxygen
Evaluate the impact of removing a predator from a food web
Overpopulation of prey and collapse of ecosystem
How does energy flow between producers and consumers?
Energy captured by producers is passed to consumers through food
