(c) In soils that lack oxygen, plants cannot absorb enough nitrates from the soil to grow well. Explain why.

Explanation:

Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. ... This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .
