Answer: B. Avoid water pollution.

Natural resources on earth are of two types called as renewable resources and non-renewable resources. The renewable resources are those which can be replenished after a single use whereas the non renewable resources are those which cannot be used again once used. Renewable resources includes water, and wind. Non renewable resources includes fossil fuels, and minerals.

Although water is a renewable resource but the availability of water for the present and future generation of human population is dependent upon how it is used, protected against contamination. Avoid water pollution is the correct option because if water is kept free from contamination it will remain available for present and future population use. Even small amount of contaminants such as household waste, chemical fertilizers, pesticides, and other wastes can contaminate large amount of water reservoir.

The statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.

<h3>What is Calvin cycle?</h3>

Calvin cycle of photosynthesis is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms.

The Calvin cycle also called light independent or dark reaction is the second stage of the photosynthetic process. It is so called because it does not require light to occur.

The Calvin cycle makes use of the products of the light stage (ATP and NADPH) to synthesize carbohydrates.

However, the series of reaction is an energy consuming one, which makes use of ATP to occur.

Therefore, the statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.
