A biological community of interacting organisms and their physical environment is an ecosystem
What is an ecosystem?An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscapes, work together to form a bubble of life.
Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance. Animals that depend on plants for food and shelter will have to adapt to the changes, move to another ecosystem, or perish.

Which factor would not increase the production of glucose by photosynthesis in plants?
Lack of water would not increase glucose production by photosynthesis in plants because water is crucial for the light reactions to produce NADPH and ATP, which are needed in the Calvin cycle to synthesize glucose. Insufficient water impacts the entire photosynthetic process, leading to decreased glucose production.
Explanation:A factor that would not increase the production of glucose by photosynthesis in plants is a lack of water. Water is essential for the light reactions of photosynthesis, where water molecules are split to form oxygen, electrons, and protons. These electrons and protons are then used to generate NADPH, which, along with ATP produced in the light reactions, is used in the Calvin cycle to synthesize glucose. Without sufficient water, these processes can't occur optimally, and the production of glucose by photosynthesis would decrease.
Regarding the statement about how an increase in temperature causing faster diffusion of CO2, and consequently, a potential increase in the rate at which plant leaves lose CO2; if all other conditions are favorable for photosynthesis, the increased loss of CO2 may lead to reduced availability of CO2 for the Calvin cycle. This can result in a decrease in photosynthesis (as per option d.), since there would be less CO2 to be fixed into glucose.
The products of the Calvin cycle are glucose and other sugar molecules as well as the regeneration of the molecule RuBP which is necessary for the cycle to continue.
If a plant lacks a photosystem II complex due to a mutation, it would not be able to initiate the light-dependent reactions of photosynthesis, leading to a failure to produce the essential compounds like ATP and NADPH required for the Calvin cycle, thus disrupting the synthesis of glucose.
Plants that lack sunlight or sufficient water would not be able to perform photosynthesis efficiently, which would impact not only the plant's survival but also the organisms that rely on those plants for food, leading to broader ecological consequences.
Exposure to only red light can still support photosynthesis, although the rate may vary depending on the specific species of plant and its adaptations to light conditions (as per options b. and c.).
Factors not increasing photosynthesis include a lack of water or insufficient CO₂, both crucial for the Calvin cycle. A mutation removing photosystem II would inhibit photosynthesis, and only red light exposure can also affect the rate of photosynthesis. Plants without sunlight or water would produce less glucose, impacting dependent organisms.
Explanation:Factors that do not increase the production of glucose by photosynthesis in plants include a lack of water or inadequate carbon dioxide (CO₂). A lack of water would prevent hydrogen ions (H+) and NADP+ from forming NADPH, which is essential for the Calvin cycle of photosynthesis. Not enough CO₂ would limit the number of carbon molecules available to be fixed into glucose during the Calvin cycle. Additionally, an increase in temperature might lead to a faster loss of CO₂ from plant leaves, affecting the Calvin cycle by slowing it down due to insufficient carbon to fix in the system. This could potentially lead to lower glucose production if light and water are adequate.
The products of the Calvin cycle, which depend on carbon fixation, are carbohydrates and regenerated RuBP (ribulose bisphosphate), which is critical for the cycle to continue. If a plant had a mutation that eliminated its photosystem II complex, it would not be able to split water molecules to generate oxygen, hydrogen ions, and electrons essential for the formation of NADPH and ATP, thus hampering the photosynthetic process and preventing glucose production.
With only red light exposure, the rate of photosynthesis in a plant could potentially decrease or follow a complex pattern where it decreases and then increases, depending on the specific wavelength of the red light and the plant's individual response to it. For plants lacking sunlight as an energy source or sufficient water, photosynthesis would be inhibited, reducing glucose production and potentially affecting those organisms that rely on plants for survival.

Mice eat corn. Hawks eat mice. Which term describes the corn in this food chain?
a. secondary consumer
b. primary consumer
c. producer
d. decomposer
The correct answer is producer.
The term producer means the autotrophic plants that makes food for themselves. The primary consumer such as mice feeds on the producer (corn) for their energy requirement. Producers lie at the first level of the food chain. Producers are the blue-green plants that makes food by the process of photosynthesis by using sunlight.

The common ancestor of the protostomes had a coelom. what does this suggest?
Which of the following is not a piece of molecular evidence supporting the endosymbiotic theory?
The mitochondria and chloroplasts are much different in structure than bacteria. Hence the correct option is a.
One piece of molecular evidence supporting the endosymbiotic theory is the similarity between the DNA of mitochondria and chloroplasts and that of bacteria. This similarity suggests that mitochondria and chloroplasts may have originated from free-living bacteria that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
Additionally, the presence of ribosomes in mitochondria and chloroplasts that resemble those found in bacteria further supports this theory. Moreover, the mechanism of division by fission, which is similar to bacterial reproduction, observed in some organelles like mitochondria and chloroplasts provides further evidence for their bacterial origins.
However, the structural differences between mitochondria, chloroplasts, and bacteria do not directly support the endosymbiotic theory but rather suggest evolutionary adaptations that have occurred over time. Therefore, option A is not a piece of molecular evidence supporting the endosymbiotic theory. Hence the correct option is a.

Which of the following describes the most likely impact of seafloor mining on the surrounding marine environment?
A.) Alteration in seafloor sediments rich in carbon would cause loss of species and an unbalanced population in marine food webs.
B.) Increased levels of metals in the ocean would result in decrease of marine bivalves due to weakened shells.
C.) Methane gas would pollute the marine environment and cause an overabundance of bacteria that feed on it.
D.) Nonrenewable resources in the marine environment would become depleted and affect the balance of the ecosystem.
Answer: A.) Alteration in seafloor sediments rich in carbon would cause loss of species and an unbalanced population in marine food webs.
Explanation:
The seafloor mining will have a drastic impact over the sea ecosystem. The mining process will expose the partially decomposed organic matter to the sea water. This will result in the increase in abundance of the organic carbon in the sea water. This will readily absorbed by the aquatic plants but the increase in abundance will likely to kill sea animals because carbon is the waste material discharged by the organisms and oxygen is the basic requirement for all the cells of the body. This will negatively influence the populations of the marine food webs.
