Explain why each of the following misconceptions about photosynthesis is false:1 Plants do not need cellular respiration because they carry out photosynthesis2 Chlorophyll is the only plant pigment.3 Only plants are autotrophs.

Photosynthesis is a process that helps cycle matter through the environment, the statement is correct because in plants oxygen is released and carbon dioxide is absorbed.

The process through which green plants and certain other organisms convert light energy into chemical energy is known as photosynthesis.

Light energy is collected and utilized by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.

Photosynthesis produces oxygen and glucose by combining sunlight, carbon dioxide, and water.

Answer:

The population has decreased because the number of live births has decreased.

The evidence suggests that the population has decreased because of the lack of food availability and resource population due inappropriate management of habitat. The parrots losing their resource population has affected the reproduction cycles of the breeding females causing lower live births in these parrots.  

Climate change also should be taken into account, with the everyday change in the climate it makes for migration to populated breeding grounds unmanageable. If this proves to be the case then an artificial climate controlled sanctuary may be one of the last hopes to saving this breed on parrot.  

Based on the evidence, I conclude that improving or creating an ecosystem where the food resources are plentiful and the climate was sustainable would increase the breeding of the animal.

Explanation: Hope this Helps.

The African animals given in the chart are lions, cheetahs, and zebras. The chart presents their population sizes in 1990 and 2000. The population of zebras is higher than the lion and cheetah populations. The lions' population declined from 100,000 to 47,000 between 1990 and 2000 is Lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.

Likewise, the population of cheetahs decreased from 7,500 to 2,500 between 1990 and 2000. However, the population of zebras remained relatively stable at 50,000. Therefore, one could deduce that lions and cheetahs are competing for the same food source, which is zebras.

Lions and cheetahs have a diet that includes zebras. As a result, zebras serve as a food source for both lions and cheetahs. This indicates that there is competition between lion and cheetah populations. It is important to remember that the population of zebras remained stable during this period, indicating that the food source remained plentiful. As a result, the reason for the decline in lion and cheetah populations must be due to other factors.

Therefore, the statement that is best supported by the numbers in the chart is that lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs. The decline in lion and cheetah populations could be attributed to numerous causes, including habitat loss, disease, and human interference, among other factors.

Approximately 10% of energy is transferred from one step in a food chain to the next.

A food chain is a sequence of organisms in which each depends on the next for food. The chain starts with producers, who are then eaten by primary consumers, which are then eaten by secondary consumers, and so on.

Energy flows up the chain, from lower to higher levels of trophic levels, meaning that the food chain in an ecosystem is unidirectional because the energy that moves through the food chain only travels in one direction, from the producers to the top-level consumers.

Approximately 10% of energy is transferred from one step in a food chain to the next. The 10% Rule describes the law of thermodynamics that regulates the transfer of energy from one trophic level to the next. This rule states that just about 10% of the energy available at a trophic level is transferred to the next trophic level.

When a rock transforms into another type of rock, the scale at which these changes are occurring is at the atomic level, which is option D.

Rocks are composed of minerals, which are made up of different combinations of atoms. During the process of rock transformation, such as through the geological processes of metamorphism or igneous activity, the arrangement and composition of the atoms within the minerals change. This leads to the formation of new minerals and the alteration of the rock's properties.

At the atomic level, the atoms within the minerals may rearrange themselves, forming new bonds and crystal structures.

This can result in changes in the physical characteristics of the rock, such as its texture, color, or mineral composition.

The transformation may involve the loss or gain of atoms, leading to changes in the overall chemical composition of the rock.

Therefore, the changes occurring when a rock transforms into another type of rock primarily occur at the atomic level, as the atoms within the minerals undergo reorganization and bonding to create a new rock with distinct properties.

Therefore, the correct answer is D.

Optimum conditions for enzymes refer to the specific environmental conditions that allow enzymes to function at their highest efficiency. These conditions include factors such as temperature, pH, substrate concentration, and the presence of any necessary cofactors or coenzymes.

Temperature: Each enzyme has an optimal temperature at which it works most effectively. Typically, enzymes in the human body function optimally at around 37 degrees Celsius, but there are exceptions. Extreme temperatures can denature enzymes, rendering them non-functional.

pH: Enzymes also have an optimal pH range in which they exhibit peak activity. Different enzymes have different pH optima depending on their specific function and location in the body. For example, stomach enzymes, like pepsin, work optimally in acidic conditions, while intestinal enzymes, like pancreatic amylase, prefer a more alkaline environment.

Substrate Concentration: Enzyme activity is often influenced by the concentration of the substrate. Initially, as substrate concentration increases, the enzyme activity also increases, until a point of saturation is reached where all enzyme molecules are occupied. At this point, further increases in substrate concentration do not enhance enzyme activity.

Cofactors and Coenzymes: Some enzymes require the presence of specific ions or organic molecules called cofactors or coenzymes to function optimally. These molecules assist in the enzyme-substrate binding or participate in the catalytic reaction.

Understanding and controlling the optimum conditions for enzymes is crucial in various fields, including biochemistry, medicine, and industrial applications. It allows for the efficient utilization of enzymes, enhancing their effectiveness and overall performance.
