What is a food chain ?
A food chain shows the sequence of how organisms obtain their energy.
A food chain usually starts with a plant and ends with an animal. To complete the cycle, decomposers come in to clean up the waste and return nutrients to the soil.
Simply stated that food chain represents the series of events in which food and energy are transferred from one organism to another in an ecosystem.

The culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.
Arctic outbreak"Bursts" of cold air like this are usually confined to the Arctic region thanks to a series of low-pressure systems, says the NWS. However, one of these waves advanced through Canada and "escaped" to the US.
According to experts heard by Reuters, it is a vast mass of icy air in the atmosphere, which brings with it frigid temperatures - which can be prolonged if storms form.
From this information we can conclude that according to the US Weather Service (NWS), the culprit is an "arctic outbreak" that originated just above the US-Canada border, which is freezing temperatures across much of the US territory.

BRAINLYEST QUESTION A drug company performed a study to test the effectiveness of a new headache medicine. The researchers grouped the patients into two different groups. One group was given the pills that contained the new medicine. The other group were given pills that did NOT contain the new medicine. Why did the researchers NOT tell the patients which pill they were given?
A) to make sure they didn't get angry
B) to prevent errors in data collection
C) to keep people from leaving the study
D) to prevent bias in the data collection
Answer:
D) to prevent bias in the data collection
Explanation:
If the researchers told the patients of the pill they took, it could create bias.
Bias can make the experiment's outcome end in a different way because of the way it influences the people taking the pill.
Bias can create another factor in an experiment, making your results unreasonable due to the addition of another factor.

How do many seeds arrive in a barren landscape?
Answer:
Hope it helps!~ (Sorry I you get it wrong or I got It wrong-)
Explanation:
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. ... Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants.

What is the speed of a wave with a frequency of 2 Hz and a wavelength of 87 m?
Group of answer choices
0.023 m/s
43.5 m/s
89 m/s
174 m/s
The speed of a wave with a frequency of 2 Hz and a wavelength of 87 m will be 174 m/s. Thus, the correct option will be D.
What is Wave speed?Wave speed can be defined as the magnitude of distance which the wave travels in a given amount of time, such as the number of meters which it travels per second of time.
Wave speed is a scalar quantity as it has only magnitude and no direction. Speed of a wave depends upon the medium in which the wave travels.
The wave speed is directly proportional to the wavelength of the wave and the frequency of the wave. Speed of a wave is the product of its wavelength and frequency. The expression for wave speed is as follows:
Speed of wave = Wavelength × Frequency
Speed of wave = 87 × 2
Speed of a wave = 174 m/s.
Therefore, the correct option will be D.

Describe how the available energy in the marine ecosystem of the Pacific Northwest could be different than that of African savanna.
Answer:
Savannah is located near the equator has more energy availability.
Explanation:
Maine ecosystem of the pacific northwest consists of open ocean and is influenced by the seasonal upwelling events and has freshwater and saline water bodies. It has an average temperature of 39 °F but is warmer near the equator. While the African savanna is a tropical grassland ecosystem and has warm temperature year-round is characterized by grasses and dispersed trees. The sunlight easily reaches the ground and the vegetation is dense and the climate usually warm with 20 to 30° C with an annual rainfall of 30 inches per year.The African savanna has more available energy than the marine ecosystem of the Pacific Northwest.
The African Savannah is an ecosystem that is characterized by:
warm temperatures throughout the year,grasses and small or dispersed trees that do not form a closed canopy, andhighest seasonal rainfall in the summer.The Pacific Northwest is a marine ecosystem that is characterized by:
mixture of climates andabundance of mountain ranges.The African Savannah has more available energy than the marine ecosystem of the Pacific Northwest because it is closer to the equator than the marine ecosystem of the Pacific Northwest.

Bro, what are the questions?
Explanation:
Tia and Trey want to study the effect of fertilizer on cherry tomato growth. They set up fifteen Husky Cherry plants in the same pots with 500 mL of the same soil. They make 5 groups of three plants. Group 1 gets no fertilizer and the other four groups receive different amounts of fertilizer (1-4 teaspoons). Each day the plants get 300 ml of water. After two months they count the number of tomatoes that have turned red.
That pot which recieves suitable amount of fertilizer will have more number of red tomatoes as compared to other plants.
Which pot has large number of tomatoes?Application of optimum dose of fertilizers enhance the vegetative growth of plants which results in the production of large number of fruits on that plant.
So we can conclude that that pot which recieves suitable amount of fertilizer will have more number of red tomatoes as compared to other plants.

Why are carbon reservoirs important in the carbon cycle?
Answer: Carbon compounds regulate the Earth's temperature, make up the food that sustains us, and provide energy that fuels our global economy. Most of Earth's carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
Carbon compounds govern the Earth's temperature, provide food for us to eat, and provide energy to power our global economy.
What is carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the atmosphere into organisms on Earth and then back into the atmosphere.
Carbon is found in carbon dioxide, a greenhouse gas that works to trap heat near the Earth.
It assists Earth in retaining the energy it receives from the Sun, preventing it from escaping back into space. The Earth's ocean would be frozen solid if it weren't for carbon dioxide.
The ocean, geologic reserves of fossil fuels, the terrestrial surface, and the atmosphere are the primary carbon reservoirs. Reservoir sizes are estimated in trillions of kilograms of carbon.
Thus, the carbon reservoirs are important in the carbon cycle.

How were the cardiovascular, respiratory, and excretory body systems working together?
Engineers use pieces of metal, called heat sinks, to conduct heat away from computer chips so that the chips do not melt. A newly designed computer chip produces too much heat and requires a new type of heat sink to remove the excess heat. What type of heat sink could the engineer build to keep the new chip cool?
Answer:
the engineer should build a water-cooled heatsink
Explanation:
If a regular full metal heatsink is not working due to the computer chip producing too much heat then the engineer should build a water-cooled heatsink. These are usually metal heatsinks that are filled with water. Since water has a great heat capacity it is able to retain heat very efficiently without actually warming up the water (to a certain degree). Therefore, a water heat sink is able to take the heat produced from the CPU and cool down the CPU by dissipating that heat in the water.
