Photosynthesis & Cellular Respiration
The products of photosynthesis.
What is glucose and oxygen?
What is the difference between an abiotic and biotic factor?
Biotic: has lived, is currently living, or has the potential to live.
Abiotic: non-living but naturally found.
What is it called when something remains the same in an experiment?
Constant.
How do you estimate the carrying capacity of an ecosystem on a graph?
Look between the peaks and the valleys of the line on the graph and estimate.
The amount of energy available to primary consumers.
What is 10%?
The types of organisms that photosynthesize.
What are autotrophs?
All living things are made of _____.
Cells.
We believe Ms. Haug is allergic to stinky cologne. How would we test this? Identify the independent and dependent variables.
Independent: cologne (what we're changing)
Dependent: whether or not Ms. Haug sneezes (what we're measuring; the result)
What is biodiversity? What are two threats to biodiversity?
The variety of life.
Over-hunting, over-population, food waste, deforestation, pollution, invasive species, climate change
What is the difference between a food chain and a food web?
A food chain is linear, a food web is consistent of many food chains, showing how they interconnect.
The primary product of cellular respiration.
What is ATP?
What are 5 characteristics all living things share?
We believe Ms. Haug is allergic to stinky cologne. How would we test this? Identify the control and at least 2 constants.
Control: not wearing cologne (the normal/baseline to compare to)
Constants: Ms. Haug, what other chemicals are around, where Ms. Haug is
What is an ecosystem service? Explain each of the four types.
Cultural - experience/education gained from nature
provisional - provides humans with a product
regulating - keeps the ecosystem healthy
supporting - natural processes that allow ecosystems to exist
What is the role of a decomposer?
To break down dead, organic matter and return the nutrients to the soil for producers to continue growing.
What process slows down at night, and what process is consistent no matter the time of day.
What is photosynthesis & cellular respiration? (in that order)
Communities interacting with abiotic factors within a certain area are called _____.
ecosystems.
The independent variables of a plant experiment are temperature and growing time. The dependent variable is height of the plant. What's wrong with this experiment?
There can only be one independent variable.
What are two benefits of biodiversity?
All ecosystem services!
Is it possible for one organism to be multiple tropic levels in a food chain/web? Explain.
If an organism is a part of different food chains within a food web, it can serve as different roles in different food chains (ex. primary consumer & secondary consumer, etc.)
The exact equation for photosynthesis & cellular respiration.
6CO2 + 6H2O --> C6H12O6 + 6O2
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
Ingestion/nutrition is a characteristic of life. Explain how these are different in animals and plants using vocabulary terms.
Autotrophs: make their own food. (plants, some bacteria, algae)
Heterotrophs: Need to gather their food from other places. (animals, fungi, most bacteria)
What variable goes on the x-axis? What variable goes on the y-axis?
X: independent
Y: dependent
What are the three types of limiting factors? Explain how they are limiting factors.
Limiting factors are things that restrict a population from continuously growing. The three types are space, food and weather conditions.
What law of science is illustrated by food webs? Explain.
Law of conservation of matter; matter cannot be created or destroyed, only changed from one form to another.
