Photosynthesis
What are the inputs (or reactants) in photosynthesis?
Carbon dioxide, Water, and Sunlight
What are the inputs (or reactants) in cellular respiration?
glucose and oxygen
What is Biodiversity?
Biodiversity is the variety of species in an area
What is a biotic factor? Give one example.
Something living
What are the products of photosynthesis?
Glucose and Oxygen
What are the products of cellular respiration?
Water, Carbon dioxide, and energy
Give a natural event that could reduce biodiversity
wildfire, volcanic eruption, drought, hurricane, flood
What is an abiotic factor? Give one example.
Something non-living
What is this molecule? C6H12O6
Glucose
What is ADP?
A source of energy for cells.
Give a man made event that could reduce biodiversity
habitat destruction (deforestation), pollution, overfishing, urbanization
Explain what happens to a population if its main food resource becomes limited.
Population decreases
Why is photosynthesis beneficial to animals?
Makes oxygen or could provide food.
What types of organisms use cellular respiration?
Animals
Explain how introducing a nonnative (invasive) species can affect biodiversity.
An invasive species can outcompete native species for resources, reduce native populations, and alter ecosystem functions
Explain how the chemical equation for cellular respiration is related to the chemical equation for photosynthesis.
Energy flows from sunlight → producers (plants) via photosynthesis into chemical energy in sugars → consumers/decomposers via cellular respiration, releasing energy as ATP and CO2 back to the environment
What organelle does photosynthesis take place in?
The chloroplast
What organelle does cellular respiration take place in?
Mitochondria
Describe one strategy humans can use to protect or increase biodiversity.
habitat protection/restoration, protected areas, pollution reduction, controlling invasive species, sustainable resource use
Describe how increased biodiversity can make an ecosystem more stable
More biodiversity provides more species that can fill similar roles or respond differently to change; this redundancy and variety of interactions helps the ecosystem resist or recover from disturbances (increases resilience/stability)
