Please check my answer!
Fill in the blank for below:
Resources that cannot be replaced in the environment once they are used
are _____.
renewable resources
compost
nonrenewable resources
I think the answer is nonrenewable resources.I might be incorrect, so please check!
This is another question, but I am having issues on it and cannot get it right. Please help me to find the answer.
In which natural cycle must an important gas in Earth's atmosphere be fixed
before plants can use it?
sulfur cycle
carbon cycle
nitrogen cycle
oxygen cycle
Please help!
1 is correct.
2. Nitrogen must be fixed.
Thanks so much! :)
For the first question, you are correct! The answer is indeed nonrenewable resources. Nonrenewable resources are those that cannot be replaced or are replenished too slowly to meet the rate of consumption. These resources, once used, are gone forever or take millions of years to form again, such as fossil fuels like coal, oil, and natural gas.
Now let's move on to the second question. To find the correct answer, we need to understand the natural cycles and their role in the Earth's ecosystem.
The nitrogen cycle is the process in which nitrogen is converted between its various chemical forms in the environment. It includes processes like nitrogen fixation, nitrification, denitrification, and assimilation. However, the plants do not require an important gas in the atmosphere to be fixed before they can use it.
The sulfur cycle is the biogeochemical cycle that describes the movement of sulfur through various reservoirs such as the atmosphere, rocks, soils, and water bodies. While sulfur is important for various biological processes, plants do not require a particular gas to be fixed before they can use it.
The oxygen cycle is the circulation and reutilization of oxygen within the biosphere, atmosphere, and lithosphere. It involves processes like photosynthesis, respiration, and combustion. However, plants release oxygen during photosynthesis rather than needing a gas to be fixed.
Therefore, the correct answer is the carbon cycle. In the carbon cycle, carbon dioxide (CO2) in the atmosphere is fixed by plants through photosynthesis to produce glucose and other organic compounds. This fixed carbon is then used as a source of energy and building blocks for plant growth. So, before plants can use carbon dioxide, it must be fixed in the carbon cycle.
I hope that clears up any confusion and helps you understand how to approach these types of questions in the future!
