When rain changes to ice pellets what happens to the temperature?
Answers
Explanation:
When rain changes to ice pellets, the temperature at the surface usually drops. This is because the process of rain changing to ice pellets, also known as sleet or graupel, involves the raindrops passing through a layer of freezing air near the surface. As the raindrops fall through this layer of cold air, they freeze into ice pellets.
This process releases latent heat, which is the energy absorbed or released by a substance during a change in state. In this case, as the water droplets freeze into ice pellets, they release latent heat, which slightly warms the surrounding air. However, this warming effect is generally offset by the cooling effect of the freezing air near the surface, resulting in a net drop in temperature.
It's worth noting that the specific temperature change will depend on various factors, such as the temperature and humidity of the air mass, the intensity of the precipitation, and the duration of the sleet or graupel event. In some cases, the temperature drop may be relatively small, while in other cases, it may be more significant.
The temperature suddenly becomes colder.

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.

Answers
Answer:
air or co2
Explanation:
if the wind force is going to be pushed. by air whoch cretaes an atmosphere with water
Answer:
The correct answer is - waves.
The frictional force of the winds is the force with which the winds influence a surface. The smoother a surface is the lesser the friction, and vice versa. The water is a smooth surface, so the winds frictional force is not very big on it, but it is big enough to cause the occurrence of the waves. By constantly influencing the water with their frictional force the winds manage to move and disrupt the surface of the water, with the end result being the waves. Depending on the strength of the winds and the frictional force accordingly to that the waves can be very small, only few mm in height, or can be up to several meters in height.

• also known as tropical grasslands
• 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.

1. What is an ecosystem?
2. What are some examples of nonliving things in an ecosystem?
3. What are some factors that could affect the number of organisms in an ecosystem?
4. Why might organisms interact in an ecosystem?
5. Would you expect to find the same kinds of interactions between organisms in very different ecosystems? Why or why not?
6. Why is it important to understand feeding relationships in an ecosystem?
Answers
Examples of nonliving things in an ecosystem include sunlight, water, air, rocks, soil, and minerals.
Factors that could affect the number of organisms in an ecosystem include the availability of food and water, temperature, weather conditions, availability of shelter or habitats, the presence of predators and disease, and human activities such as deforestation or pollution.
Organisms interact in an ecosystem to obtain resources such as food, water, shelter, and mates, and to avoid being eaten by predators or infected by diseases. Some organisms also form mutualistic relationships, where both parties benefit from the interaction.
Different ecosystems can have different organisms and interactions based on the unique features of each ecosystem, such as climate, geography, and available resources.
Understanding feeding relationships in an ecosystem is important because it helps us understand the flow of energy and nutrients through the ecosystem. This knowledge can inform conservation efforts and help us manage and protect ecosystems for the benefit of all living organisms, including humans.
Answer:
1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.
2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.
3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.
4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.
5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.
6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.
