A group of students is studying the types of plants that grow in a meadow next to their school. The meadow is mowed regularly, but it does not get any water other than rainfall. The meadow has several kinds of plants that are typically found in a grassland ecosystem. The plants include grass and clover. But there aren't any trees. The meadow has insects, including ants. Earthworms live in the soil. Garter snakes and mice also live in the meadow.
The factors that affect an ecosystem such as rainfall, sunlight etc are all factors in this experiment.
What are factors?The term factors in an experiment setting refers to the variables that are being manipulated in the experiment. Usually, factors are altered to determine its effect on the results.

If equal masses of sand and water are heated to the same temperature, which sample will absorb more energy? Base your argument on the definition of heat and what you learned from the experiment.
It depends on the specific heat capacity of the sand and water samples, which is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius.
What is specific heat?Specific heat is a physical property of a substance that describes the amount of energy required to raise the temperature of a given amount of the substance by one degree Celsius (or one Kelvin).
According to the definition of heat, it is a form of energy that is transferred between two substances due to a difference in temperature.
The amount of heat transferred between two substances is proportional to the temperature difference and the specific heat capacity of the substances.
In general, water has a higher specific heat capacity than sand, which means that it takes more energy to raise the temperature of a given mass of water compared to the same mass of sand.
Therefore, if equal masses of sand and water are heated to the same temperature, the water sample will absorb more energy compared to the sand sample.

D. Use more fuel-efficient cars.
Answer:
its D
Explanation:
we use alot of fuel so i feel like somthing making better use of fuel would help over all decrease the total amount we use paper is made from trees wich absorb carbon dioxide and that help decrease global warming so more paer products means less trees and more global warming plastic products create carbon dioxide and cause global warming in order to produce so i stand by my awnser. not sure about the electricity part.
Which compares the gases released by fertilizers and gases from landfills?
A. Chemicals from fertilizers can release nitrous oxide, while landfills release methane.
B. Chemicals from fertilizers can release methane, while landfills release nitrous oxide.
C. Chemicals from fertilizers can release carbon dioxide, while landfills release methane.
D. Chemicals from fertilizers can release methane, while landfills release carbon dioxide.
Answer: a
Explanation: tell me if wrong and sorry
The powerful greenhouse gas nitrous oxide is released into the atmosphere when a large portion of the fertilizer that has been applied runs off into waterways or is broken down by soil bacteria. Thus, option A is correct.
What are the gaseous release by fertilizers?MSW goes through an aerobic (with oxygen) decomposition stage in a landfill when it is initially dumped, during which little methane is produced.
Once anaerobic conditions have been established, which normally takes less than a year, methane-producing bacteria start to break down the waste and produce methane.
However, their creation and usage have a negative impact on the environment since they release nitrous oxide.
Therefore, Chemicals from fertilizers can release nitrous oxide, while landfills release methane.

Answer:
Explanation:
fossil energy sources, including oil, coal, and natural gas, are non-renewable resources formed when prehistoric plants and animals died and were gradually buried by layers of rock.
The nation's wind supply is abundant and inexhaustible. Over the past 10 years, U.S. wind power capacity has grown 15% per year, and wind is now the largest renewable power source in the United States. It's sustainable. Wind is actually a form of solar energy.
The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
hydroelectric is a renewable energy source. Hydroelectricity uses the energy of running water, without reducing its quantity, to produce electricity.
