1. Which are examples of different energy roles in a food chain?

Explanation

The correct answer is producer, consumer, decomposer. In a food chain, producers are organisms that produce their own food through photosynthesis or chemosynthesis. Consumers are organisms that obtain energy by consuming other organisms. Decomposers are organisms that break down dead organic matter and recycle nutrients back into the ecosystem. These three roles represent different levels of energy transfer and flow within a food chain.

Flow Of Energy/Recycling Of Matter Review I - Quiz

This quiz covers key concepts in energy flow and matter recycling within ecosystems, including roles in food chains, photosynthesis, and nitrogen fixation.

2. Which type of organism can convert free nitrogen into nitrogen compounds?

Explanation

Bacteria are capable of converting free nitrogen into nitrogen compounds through a process called nitrogen fixation. They have the ability to convert atmospheric nitrogen gas into a form that can be used by other organisms, such as plants. This is an important process as nitrogen is an essential nutrient for the growth and development of living organisms. Plants, producers, and fungi do not have this ability, making bacteria the correct answer.

Submit
3. Which gas makes up most of the earth's atmosphere?

Explanation

Free nitrogen makes up most of the earth's atmosphere. This is because nitrogen gas (N2) is the most abundant gas in the atmosphere, comprising about 78% of the total volume. Oxygen, carbon dioxide, and ammonium are present in much smaller quantities compared to nitrogen.

Submit
4. Producers are an important part of what cycle(s)?

Explanation

Producers are organisms that convert sunlight into energy through the process of photosynthesis. In order to carry out this process, producers require carbon dioxide from the atmosphere, water from the environment, and nutrients from the soil. Additionally, nitrogen is also an essential nutrient for producers, as it is needed for the synthesis of proteins and nucleic acids. Therefore, producers are an important part of the carbon, water, nutrient, and nitrogen cycles.

Submit
5. Lightning helps to recycle what element?

Explanation

Lightning helps to recycle nitrogen. During a lightning strike, the high temperature and energy cause the nitrogen gas in the atmosphere to react with oxygen and form nitrogen oxides. These nitrogen oxides then dissolve in rainwater and fall to the ground, where they can be absorbed by plants and used to make proteins. Eventually, the nitrogen is returned to the soil and can be reused by other organisms in the ecosystem.

Submit
6. Which "ation" word refers to when water vapor loses energy and turns back into water droplets?

Explanation

Condensation refers to the process in which water vapor loses energy and turns back into water droplets. This occurs when the temperature of the air decreases, causing the water vapor to condense and form visible water droplets. Precipitation refers to any form of water that falls from the atmosphere to the Earth's surface, such as rain, snow, or hail. Respiration is the process by which organisms convert oxygen and glucose into energy, while transpiration is the process by which plants release water vapor into the atmosphere through their leaves. Therefore, the correct answer is condensation.

Submit
7. Which two substances are created during photosynthesis?

Explanation

During photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Glucose is a sugar molecule that serves as a source of energy for the plant, while oxygen is released as a byproduct. Therefore, the correct answer is glucose and oxygen.

Submit
8. The gas responsible for turning bromothymol blue to bromothymol yellow in our snail lab was

Explanation

In our snail lab, bromothymol blue changed from blue to yellow, indicating a change in pH. Carbon dioxide is known to dissolve in water and form carbonic acid, which lowers the pH and causes the color change. Oxygen, nitrogen, and carbon do not have the same effect on pH, so they cannot be responsible for the color change. Therefore, the gas responsible for turning bromothymol blue to bromothymol yellow in our snail lab was carbon dioxide.

Submit
9. Check all that apply to what we know about N

Explanation

The correct answer choices are "formula for free nitrogen gas in the air," "made of 2 atoms," and "element." These choices accurately describe what we know about N2. Nitrogen gas (N2) is the formula for free nitrogen gas in the air, meaning it is the chemical formula that represents nitrogen gas in its natural state. It is made up of two atoms of nitrogen, as indicated by "made of 2 atoms." Lastly, nitrogen (N) is an element, as it is a pure substance that cannot be broken down into simpler substances.

Submit
10. Check all that apply!    Energy

Explanation

Energy comes to the earth in the form of sunlight because sunlight is a major source of energy for the earth. It must be converted into a form that organisms can use by the producers on earth, such as plants through photosynthesis. This converted energy is then made available to consumers through food chains, as organisms consume other organisms to obtain energy.
