ECOSYSTEMS
We call this all the different populations of species living and interacting in an area
What is a community?
DNA stands for this
What is deoxyribonucleic acid?
The temperature dropped below freezing, so the pond froze over. This is the cause
What is the temperature dropping below freezing?
"the water is cold" an example of...
What is qualitative data?
Photosynthesis requires three main ingredients.
What is sunlight (or light energy), water, and carbon dioxide?
This organism in an ecosystem produces its own food using sunlight.
What is a producer (or plant)?
DNA is shaped like a twisted ladder. We call this shape
What is a double helix?
A student forgot to water her plant for two weeks. The effect is
What is the plant wilted (or died)?
A scientist measures that a plant grew 5 centimeters in one week.
What is quantitative data?
This is the chemical equation for photosynthesis
What is 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂?
A hawk eats a snake, and the snake eats a mouse, what is the hawk called in this food chain?
What is a top predator (or secondary consumer)?
During DNA replication, the two strands of DNA separate. This enzyme helps unzip the DNA strand.
What is Helicase?
Because the forest fire destroyed the trees, the effect to the animals that lived there was
What is they lost their habitat (or had to move)?
This type of data uses measurements...
What is quantitative data?
A farmer notices her tomato plants grow slowly on cloudy days but quickly on sunny days. This factor is limiting the rate of photosynthesis.
What is light intensity (or sunlight)?
This term describes the role an organism plays in its environment, including what it eats and where it lives.
What is a Niche?
This process creates MRna
What is transcription?
A factory released pollution into the river. Identify both the cause and one effect.
What is the cause: factory pollution, and the effect: fish died (or water became contaminated)?
A student describes a rock as "smooth, gray, and shiny." Is this qualitative or quantitative data? Explain why.
What is qualitative data because it describes qualities and characteristics rather than using numbers?
In a greenhouse, a gardener increases the temperature from 15°C to 25°C and observes faster plant growth. However, when the temperature reaches 40°C, the plants stop growing. Explain why increasing temperature beyond a certain point decreases the rate of photosynthesis.
What is the enzymes that control photosynthesis denature (or stop working) at extremely high temperatures?
In a forest ecosystem, decomposers break down dead organisms. Name one example of a decomposer.
What is a fungus (or bacteria)?
This process produces aminoacids
What is Translation?
a predator population increases, this would likely happen to the prey population as a cause and effect relationship.
What is the prey population would decrease?
A scientist collects both "the solution turned blue" and "the temperature increased by 10°C." Which is qualitative and which is quantitative?
What is "the solution turned blue" is qualitative and "the temperature increased by 10°C" is quantitative?
Compare photosynthesis and cellular respiration. How are they opposite processes in terms of reactants and products?
What is photosynthesis uses carbon dioxide and water to make glucose and oxygen, while cellular respiration uses glucose and oxygen to make carbon dioxide and water?
