Which process occurs when bacteria converts nitrogen gas to a usable form?decompositioncondensationfixationtranspiration

After Gerry mows his lawn, he often puts the grass clippings into his flower garden.How will this affect his garden?- It will decrease the amount of carbon in the soil and decrease the amount of carbon dioxide released by decomposers.- It will increase the amount of carbon in the soil and decrease the amount of carbon dioxide released by decomposers.- It will decrease the amount of carbon in the soil and increase the amount of carbon dioxide released by decomposers.- It will increase the amount of carbon in the soil and increase the amount of carbon dioxide released by decomposers.

Which processes result in the release of carbon? Select three options.- Animals break down food molecules to obtain energy.- The remains of producers are broken down by decomposers.- The remains of consumers are broken down by soil decomposers.- Producers take in carbon dioxide.- Producers make sugars and starches.

Kate wrote the steps of the carbon cycle to describe how carbon is cycled through specific organisms. The steps are in random order.1 - The rabbit decomposes.2 - The rabbit eats the carrot plant.3 - The carrot plant takes in carbon dioxide from the air during photosynthesis.4 - Carbon compounds are returned to the soil.Lists the steps in order.

Cleo has a vegetable garden and wants to increase the amount of nitrogen in the soil.How can she most likely do this?- add several soybean plants to her garden- decrease the amount of fertilizers she uses- harvest the vegetable plants continuously- reduce the number of decomposers that live in the soil

Which best describes a role of animals in the water cycle?- They help water vapor condense when they produce waste.- They help water vapor condense when they inhale.- They release water vapor through transpiration.- They release water vapor when they exhale.

Which organisms release carbon dioxide as waste?consumers onlyconsumers and decomposersproducers and decomposersproducers only

Which best explains why a thick tropical forest filled with large plants typically has a lot of water vapor in the air?The plants undergo transpiration.The plants undergo condensation.The plants prevent water from evaporating.The plants prevent water from becoming runoff.

Which best compares the roles of nitrogen-fixing bacteria and certain decomposers in the nitrogen cycle?- Both organisms convert free nitrogen into nitrogen-containing compounds.- Both organisms convert nitrogen-containing compounds into free nitrogen.- The bacteria convert free nitrogen into nitrogen-containing compounds, while the decomposers convert nitrogen-containing compounds into free nitrogen.- The bacteria convert nitrogen-containing compounds into free nitrogen, while the decomposers convert free nitrogen into nitrogen-containing compounds.

Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap.What process formed the water droplets in Scott's model?evaporationtranspirationcondensationprecipitation

During which process of the water cycle does water change from a gas to a liquid?precipitationcondensationtranspirationevaporation

How do plants obtain nitrogen?They remove it from the air.They absorb it through their roots.They fix it in their leaves.They produce it in their stems.

What is free nitrogen?- nitrogen that is ready for plants to use- nitrogen that has been fixed by bacteria- nitrogen that cannot be used by organisms- nitrogen that is returned to the soil by decomposers

During the nitrogen cycle, through which structure are nitrogen compounds first absorb into the plant?rootsleavesflowerstem

Carbon, nitrogen, and water are recycled through ecosystems many times. Which one of these eventually breaks down completely?

Which statements accurately describe the roles of decomposers in the carbon cycle? Select three options.- Decomposers release carbon dioxide into the air as waste.- Decomposers remove carbon dioxide from the air during photosynthesis.- Decomposers break down the remains of dead plants and animals.- Decomposers return carbon compounds to the soil.- Decomposers use carbon to make food molecules.

Some consumers, like lions, do not eat plants or any other producers. They only eat other animals.How do lions obtain the carbon they need?- by eating animals that have carbon-based molecules stored in their bodies- by breathing it in from the atmosphere in the form of carbon dioxide- by absorbing carbon-based molecules through their skin from the soil- by drinking water that contains carbon dioxide

Once water vapor has been released into the atmosphere, it rises and cools, turning back into a liquid. What is this process called?evaporationcondensationfixationprecipitation
