1. An organism that may be referred to as an omnivore sometimes as well as a 1st order consumer other times

Explanation

The human is the correct answer because it is an organism that can be referred to as an omnivore, as it consumes both plants and animals. Additionally, it can also be considered a 1st order consumer, as it directly consumes producers (plants) in the food chain.

2. Matter 

Explanation

The correct answer is "has mass and takes up space" because matter is defined as anything that has mass and occupies space. This means that matter has physical properties such as weight and volume, and it can be measured and observed. The other options provided in the question are not accurate explanations of matter. Potential and kinetic forms, heat and light, and the ability to do work are all related to energy, not matter.

3. What do we call the amount of all living matter on earth?

Explanation

Biomass refers to the total amount of living matter on Earth. It includes all plants, animals, and microorganisms. This term is commonly used in ecological studies to measure and understand the distribution and productivity of living organisms in different ecosystems. Biomass is an important concept in studying the Earth's ecosystems and understanding the flow of energy and nutrients through the food chain.

4. The process by which certain bacteria take free nitrogen and convert it into nitrogen compounds is called

Explanation

Nitrogen fixation is the correct answer because it refers to the process in which certain bacteria convert free nitrogen gas into nitrogen compounds that can be used by plants and other organisms. This process is essential for the nitrogen cycle and plays a crucial role in maintaining the availability of nitrogen in ecosystems. Carbon fixation is the process of converting carbon dioxide into organic compounds, transpiration is the loss of water vapor by plants, and denitrification is the process of converting nitrogen compounds back into nitrogen gas.

5. Why is CO(carbon dioxide) not found on the Periodic Table?

Explanation

CO2 (carbon dioxide) is not found on the Periodic Table because it is composed of two different elements: carbon and oxygen. The Periodic Table only lists individual elements, not compounds or molecules that are made up of multiple elements. CO2 is a compound formed by the combination of carbon and oxygen atoms.

6. Place these in the order of smallest to largest.  Think about this, and I know you can figure it out....

Explanation

The correct order from smallest to largest is subatomic particles (such as protons and electrons), atoms, molecules, organelles, and living cells. Subatomic particles are the smallest units of matter, followed by atoms which are made up of subatomic particles. Molecules are formed when atoms bond together. Organelles are small structures within cells that perform specific functions. Lastly, living cells are the basic units of life and are made up of organelles.

Submit
7. The law of Conservation of Matter states

Explanation

The law of Conservation of Matter states that matter cannot be created or destroyed, although it can change form. This means that the total amount of matter in a closed system remains constant over time. It may undergo physical or chemical changes, but the total mass remains the same. This principle is fundamental in understanding the behavior of matter and is applicable in various scientific fields such as chemistry and physics.

8. Check all that apply!  Which help to describe water?

Explanation

The smallest particle of water is a molecule because water is a covalent compound made up of two hydrogen atoms bonded to one oxygen atom. Water is a compound because it is made up of two or more different elements chemically bonded together. Water is composed of hydrogen and oxygen because it consists of two hydrogen atoms and one oxygen atom.

9. The arrow in a chemical equation reads:

Explanation

The arrow in a chemical equation represents the process of "produces". It indicates the transformation of reactants into products during a chemical reaction. This arrow signifies that the substances on the left side of the equation react and result in the formation of the substances on the right side of the equation. Therefore, the correct answer is "produces".

Submit
10. Plants return water to the atmosphere through

Explanation

Plants return water to the atmosphere through transpiration, which is the process of water loss from the leaves of plants. During transpiration, water is absorbed by the roots and transported to the leaves, where it evaporates through small openings called stomata. This water vapor then enters the atmosphere. Transpiration helps plants regulate their temperature, transport nutrients, and maintain their shape. It also plays a crucial role in the water cycle, as it contributes to the overall moisture in the atmosphere.
