Photosynthesis and Cellular Respiration
What organelle gives plants their green color?
Chlorophyll as well as Chloroplast.
What is carrying capacity?
The number of organisms that an ecosystem can sustainably support.
In an energy pyramid, who has the most number of organisms?
The base/producers
What is a niche?
An organisms job- the role an organism plays in its environment ie bees pollinating flowers.
What is the goal of all types of succession?
To create a climax community
On the board, write the equation for photosynthesis.
6CO2 + 6H20 + Sun - C6H1206 + 602 + 6H20
What is symbiosis?
A close living relationship between organisms from different species. (Beneficial to one or both organisms.)
What is a biomass pyramid?
A graph that shows the biomass of different trophic levels in an ecosystem.
What is a Keystone Species?
A species that has a very large impact on the ecosystem they inhabit, without them the ecosystem would severely struggle or cease to exist.
Random Question:
What is Mrs. Theriot's favorite holiday?
Halloween
What organisms do cellular repiration?
Organisms that can make its own food and organisms that cannot make its own food.
What does an invasive species do to biodiversity in an ecosystem?
Invasive species cause a decline in native species and disrupt important interactions between organisms.
Where does the lost energy go in a trophic pyramid?
What is a pioneer species?
A pioneer species a species that are the first to inhabit newly created environments or recently disturbed environments during the processes of primary succession and secondary succession.
What are three ways that humans negatively effect the biogeochemical cycles?
overfishing, pollution, deforestation, burning of fossil fuels, green house gasses...
How does carbon move between animals/plants in an environment?
-Plants absorb carbon from the atmosphere during photosynthesis.
-Animals eat the plants and either breathe out the carbon or it moves up the food chain.
-When plants and animals die and decay, the carbon gets released back into the atmosphere.
Why doesn't a parasite take all the host's nutrients?
Because then the parasite would be unable to live itself- you kill the host, you kill your food and shelter source.
Why is high diversity better than low diversity?
If a species were to go extinct, then the rest of the species would heavily decline.
What is a stomata and where are they located?
Stomata are tiny openings found on the surfaces of plant leaves, stems, and other green parts. They play an important role in gas exchange, allowing plants to take in carbon dioxide for photosynthesis and release oxygen and water vapor.
During the water cycle- when water vapors exit the leaves of plants and trees and are pulled into the atmosphere- this is called?
Transpiration
What is glucose metabolized into during cellular respiration?
ATP
What is the difference between logistic and exponential growth?
Exponential growth is the rapid growth of a population without limit. Logistic growth is the sustainable growth of a population that has an upper limit growth.
What is one reason that less energy is passed onto each level up the energy pyramid?
This energy loss is due to metabolic processes and heat, and only about 10% of the energy at one level is available to the next level4.
What is lactic acid fermentation and what type of organisms are able to preform it?
Lactic acid fermentation is anaerobic respiration (little to no oxygen) that breaks down sugars, producing energy in the form of ATP (2 molecules). Animals and bacteria can carry out this process when necessary.
Describe to me the differences between primary and secondary succession?
Primary succession is a type of ecological succession that takes place in an environment that is recently formed and lacks habitable soil but then is colonized for the first time by living organisms.
Secondary succession is a type of ecological succession that occurs in an environment with an already established ecosystem that gets disruption due to some events like fire or hurricane and is then re-colonized by other organisms.
