Answer:

First leve consumer: 1,000 energy units

Second level consumer: 100 energy units

Third level consumer: 10 energy units

Explanation:

First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.

The group of species in an ecosystem that are at the same level in the food chain is referred to as a trophic level. A food chain has five basic trophic levels, each of which has a different nutritional relationship to the main energy source.

The Sun is any ecosystem's main source of energy (although there are exceptions in deep sea ecosystems). Primary producers, sometimes referred to as autotrophs, receive their energy input from the Sun's solar radiation.

The first trophic level is made up of primary producers. Consumers, also known as heterotrophs, make up the remaining trophic levels; heterotrophs are unable to reproduce.

Therefore, First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.

During the Cretaceous period, high temperatures and abundant vegetation resulted in increased \(CO_2\) levels, leading to the accumulation of organic matter and the formation of good source rocks for oil and gas.

During the Cretaceous period, spanning from approximately 145 to 66 million years ago, the global carbon-climate cycle played a crucial role in the development of favorable conditions for the formation of good source rocks. The period was characterized by high global temperatures and abundant vegetation, resulting in increased carbon dioxide \((CO_2)\) levels in the atmosphere.

The elevated \(CO_2\) levels fueled vigorous photosynthesis, leading to the accumulation of organic matter in marine and terrestrial ecosystems. As this organic matter was buried and subjected to heat and pressure over millions of years, it transformed into oil and gas, creating potential source rocks. The warm climate and prolific vegetation during the Cretaceous, along with the subsequent geological processes, contributed to the formation of the rich hydrocarbon reserves that are vital to our energy resources today.

The _R-chart_ is used to monitor the centering of the process.The correct answer is c. R-chart.

The R-chart, also known as the Range chart, is used to monitor the centering of the process. It is a statistical control chart that tracks the variability or dispersion within a process by measuring the range between the maximum and minimum values of a sample. The R-chart is commonly used in conjunction with the X-bar chart (also known as the process mean chart) to monitor process performance. While the X-bar chart focuses on the central tendency or average of the process, the R-chart helps assess the spread or variability of the process.

By plotting the ranges of multiple samples on the R-chart, one can determine if the process is exhibiting consistent variation or if there are shifts or changes in the dispersion. If the ranges remain within control limits, it indicates that the process is in statistical control and the centering is stable. However, if there are points that fall outside the control limits or a systematic pattern emerges, it suggests that the process variation has changed, and further investigation or corrective actions may be necessary. Overall, the R-chart is a valuable tool for monitoring the centering of a process by assessing the variability or dispersion within the process over time.

The cause of phytoplankton blooms has traditionally been attributed to seasonal changes in ‘bottom-up’ environmental factors controlling phytoplankton division rates, such as nutrients and light 3,4,5,6,7. However, seasonal changes in phytoplankton biomass (P) represented by the biomass-specific net rate of change (r) always reflect the interplay between two dominant terms, the phytoplankton division rate (μ) and the sum of all loss (l) rates (e.g., grazing, viruses, sinking):

Explanation:

The photosynthetic production of organic carbon by marine phytoplankton plays a key role in regulating atmospheric carbon dioxide (CO2) levels, such that without this biological uptake it is estimated that present day atmospheric CO2 concentrations would be 200 ppm (50%) higher1. Phytoplankton blooms in the temperate and polar oceans play a disproportionally large role in ocean CO2 uptake, as well as being critical ecological events to which the migration patterns of marine animals, ranging from zooplankton to whales, have evolved2.

The best way to describe the evolutionary changes that occur in a finch population over time is that over time, changes in the beaks of finches led to the evolution of new species of finches.

This process is known as adaptive radiation.The finches of the Galapagos Islands are an example of adaptive radiation. They evolved from a single species of finch that migrated to the islands one to five million years ago. The finches were able to adapt to different ecological niches on the islands and develop specialized beaks for different types of food sources.In particular, the warbler finch is believed to be the ancestral species of all the finches on the Galapagos Islands. Over time, the beaks of the finches changed as they adapted to different food sources. The medium ground finch and the cactus finch live on one island, while the large cactus finch occupies another island. The changes in the beaks of these finches led to the evolution of new species of finches.

The Sun serves as the primary energy source for Earth’s climate. Some of the incoming sunlight is reflected directly back into space, especially by bright surfaces such as ice and clouds, and the rest is absorbed by the surface and the atmosphere. Much of this absorbed solar energy is re-emitted as heat (longwave or infrared radiation). The atmosphere in turn absorbs and re-radiates heat, some of which escapes to space. Any disturbance to this balance of incoming and outgoing energy will affect the climate. For example, small changes in the output of energy from the Sun will affect this balance directly.

Change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy balance and climate. Many other theories of climate change were advanced, involving forces from volcanism to solar variation. In the 1960s, the evidence for the warming effect of carbon dioxide gas became increasingly convincing. Some scientists also pointed out that human activities that generated atmospheric aerosols could have cooling effects as well.

Answer: Chloroplast

Explanation:

Plants and some algae have chloroplasts responsible for photosynthesis. Plants undergo photosynthesis to transform light energy into chemical energy. This energy is stored in the form of sugar to support their growth and provide energy. Chloroplasts have a double membrane, with the thylakoid membrane located within the inner membrane.

Photosynthesis occurs within the thylakoid membrane, which is folded into sacs called thylakoids. Chlorophyll, a green pigment, is present in the thylakoids and it absorbs light energy to split water molecules into hydrogen and oxygen. The oxygen is released into the atmosphere while the hydrogen is used to create ATP, a molecule that stores energy. ATP and hydrogen are then utilized to make sugar, the final product of photosynthesis.
