2. Energy moves around this ecosystem through a food chain. Producers (plants) use sunlight to produce energy through photosynthesis. This energy is then transferred to herbivores (rabbits), which are eaten by carnivores (hawks). Energy is lost at each level of the food chain through respiration and other metabolic processes, so the amount of energy available at each level decreases.
3. If a disease strikes the snake population, the population of hawks and rabbits would be affected. If the snake population declines, there would be fewer predators to prey on the rabbit population. This would cause the rabbit population to increase, which would lead to an increase in the hawk population as they have more food to eat. However, if the disease is severe and the snake population declines too much, there may be a shortage of food for the hawks, causing their population to decline as well.
4. If the rabbit population suddenly doubled, the effect on the grass would be negative. With more rabbits, there would be more grazing pressure on the grass, leading to overgrazing. Overgrazing can lead to a decrease in grass biomass, which can negatively affect other organisms that rely on grass for food and shelter. Additionally, with less grass available, the rabbit population may eventually decline due to a lack of food. This would cause a chain reaction that could lead to the decline of other organisms in the ecosystem.
7. So if a disease stroked the snacks population than the effect on hawks would be that they would feed off a different food source, such as the rabbit. The rabbits population would decrease and soon enough the hawk population would decrease because of the competition towards food. This happens because snakes are secondary consumers and hawks feed off both rabbits and the snakes to balance the populations. If one disappears or decreases than the hawks would aim toward the animal that has a bigger population, the rabbit. Making the rabbit population leading towards less food all around.
8. If the rabbit population doubled than the grass would decrease or would die. This would happen because there is to many consumers and the grass can not keep up with how much it is giving out. This would also lead to a decrease to the rabbit population making the population really low or back to normal, depends on how quickly the grass grows.

By adding tape to his BAAD, Cramwood increased its mass and increased

What is inertia?Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.
In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.
The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.

1.) How does air move during sea breeze?

4.) Which heats faster, land or sea?
5.) Compare the direction of air in sea breeze and land breeze.

PLS MARK ME AS BRAINLIEST
1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
3.) While sea breezes occur during the day, land breezes occur at night.
4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.
Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.
2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.
3.) The sea breeze occurs during the daytime.
4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.
5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.

• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Explanation:
Beavers, large members of the rodent family in North America, are often referred to as “ecosystem/keystone engineers” by wildlife managers. Ecosystem engineers are described as animals that create, alter, or destroy a habitat. Beavers contribute to river ecosystems by bringing down old and dead trees along riverbanks. They use these trees to make their dams. Although these dams are primarily used for protection and food storage, scientists report that these dams change the surrounding environment in different ways.
Given this information, in three to five sentences, describe a potential benefit that beavers contribute to the ecosystem as keystone engineers and describe a plausible impact that the removal of beavers could have on the surrounding ecosystem.

What are the safety issues of water that freezes and thaws?
Answers
Answer:
Water that freezes and thaws can cause several safety issues, including:
Slip and fall hazards: When water freezes on sidewalks, driveways, and roads, it can create slippery surfaces that can cause people to slip and fall, leading to injuries.
Damage to infrastructure: As water freezes and expands, it can cause damage to pipes, sidewalks, roads, and buildings. This can lead to leaks, collapses, and other structural issues that can be dangerous for people and property.
Flooding: When water thaws, it can cause flooding in low-lying areas. This can be particularly dangerous in areas prone to flooding or where there is poor drainage.
Traffic hazards: Ice on roads can make them slippery and more difficult to navigate, increasing the risk of car accidents.
Cold-related health issues: Extreme cold temperatures can cause hypothermia and frostbite, which can be dangerous or fatal if not treated promptly.
It is important to take measures to prevent and address these safety issues by taking precautions such as salting sidewalks and roads, clearing drains, and addressing leaks and other infrastructure issues promptly. It is also important to be aware of weather conditions and take appropriate precautions such as wearing warm clothing and staying indoors during extreme cold temperatures.
