If the top level consumers were eliminated from a food web would the populations in the levels below them increase without bounds
Answer:
That isn't true
Explanation:
That is not true bc if the top level consumers were removed from the food chain, then the level below would become the top level of the food chain. If that happened then the level below the NEW top level of the food chain would still be getting eaten and the food chain still goes on, just with one missing level.
Hop this Helps!

3. Where does the carbon dioxide for photosynthesis come from?
The effects of anaerobic conditions
Answer:
Under anaerobic conditions (a lack of oxygen), the conversion of pyruvate to acetyl CoA stops. In the absence of oxygen, electron transport stops. NADH is no longer converted to NAD+, which is needed for the first three stages of cellular respiration.
Explanation:
lmk if I did anything wrong
Answer:
The effects of anoxia on water and solute transport across excised roots of young maize plants (Zea mays L. cv. Tanker) grown hydroponically have been studied. With the aid of the root pressure probe, root pressure (Pr), root hydraulic conductivity (Lpr), and root permeability (Psr), and reflection (σ sr) coefficients were measured using potassium nitrate (a typical nutrient salt) and sodium nitrate (an atypical nutrient salt) as solutes. During a period of 10–15 h, anaerobic treatment (0.0–0.2 g O2·m-3 in root medium) caused a decrease of root pressure by 0.01–0.28 MPa (by 10–80% of original root pressure) after a short transient increase. For a time period of 5 h, the decrease in the stationary root pressure was not reversible. Under anaerobic conditions, roots still behaved like osmometers and were not leaky. The root hydraulic conductivity measured in osmotic experiments (osmotic solute: NaNO3) was smaller by one to two orders of magnitude than that measured in the presence of hydrostatic gradients. Both the osmotic and hydrostatic hydraulic conductivity decreased during anaerobic treatment by 28 and 44%, respectively, at a constant reflection coefficient of the solutes (σ sr=0.3−1.0). As with root pressure, changes in root permeability to water and solutes were not reversible within 5 h. Under aerobic conditions and at low external concentrations (31–59 mOsmol·kg-1), osmotic response curves were monophasic for KNO3, i.e. there was no passive uptake of solutes. Response curves became biphasic at higher concentrations (100–150 mOsmol·kg-1)- For NaNO3, response curves were biphasic at all concentrations. Presumably, this pattern was a consequence of the fact that potassium had already accumulated in the xylem. During anoxia, accumulation of potassium in the xylem was reduced, and biphasic responses were also obtained at lower potassium concentrations applied to the medium. The results are discussed in terms of a pump/leak model of the root in which anoxia affects both the active ion pumping and the permeability of the root to nutrient salts (leakage). The effects of anaerobiosis on the passive transport properties of the root (Lpr, Psr, σ sr) are in line with the recently proposed ‘composite transport model of the root’.

Based on the phylogenetic tree, which two species are most closely related?
A. Alpaca and blue whale
B. Wild boar and Angus cattle
C. Angus cattle and white-tailed deer
D. Pygmy hippopotamus and white-tailed deer
Depending on the phylogenetic tree, the two species that are most closely related are option c. Angus cattle and white-tailed deer.
Relation of two species:Angus cattle and white-tailed deer should be considered as the two species as these are closely related since it should both be taxa species that represent the close relationship in the phylogenetic tree.
Also, phgmy hippotamus and while tail dear should be less closely related as compared to the option c.
Hence, the option c is correct.

every time you see the ATP starburst or lighting symbol you should relate to it which concept
Answer:
The concept must be identified: that the energy currency for cells is ATP.
Explanation:
ATP is the abbreviation of the term Adenosine Triphosphate, the presence of its three phosphors and the dephosphorylation of them are the sources of chemical and electronic energy that our body and our cells need to be able to develop life.
The following reaction occurs in each ATP molecule used for energy purposes:
ATP + KINASE ----> ADP + P (inorganic)
Kinase is the enzyme that dephosphorylates the phosphorous molecules of ATP resulting in an ADP (adenosine diphosphate) and a free inorganic phosphorus.

Observe the food web shown above. If the gray wolf became extinct,
what conclusion about the coyote population would not be valid
based on the relationships shown in the food web?
CLEAR ALL
Answer:
No, coyote will not become the apex predator.
Explanation:
No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni che, the coyote population will decrease because the wolf feeds on coyote. As the number of coyotes increase, the number of beavers will decrease because coyote feeds on beaver. If the gray wolf became extinct, the coyote population increases in that location due to no predator.

Process where gases in the atmosphere trap heat and regulate the earth's temperature
Answer:
Green house effect.
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
Answer:
it is the natural process that warms the Earth's surface. The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse
Explanation:
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space.
Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks.
Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.
Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by 47% since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change.
Methane. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.
Nitrous oxide. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
Chlorofluorocarbons (CFCs). Synthetic compounds entirely of industrial origin used in a number of applications, but now largely regulated in production and release to the atmosphere by international agreement for their ability to contribute to destruction of the ozone layer. They are also greenhouse gases.
