The correct answer for both blanks is "Sodium".
Sodium ions are necessary in small quantities for some sorts of flora, but sodium as a nutrient is extra usually wanted in large quantities by using animals, due to their use of it for era of nerve impulses and for upkeep of electrolyte balance and fluid stability. In animals, sodium ions are vital for the aforementioned capabilities and for coronary heart hobby and sure metabolic functions.
<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>
Explanation:
Let us understand the term DDT
DDT : Dichlorodiphenyltrichloroethane
- This is a crystalline chemical compound
- Basically used for protecting insects eating crops
- It is colorless, odorless, tasteless
- Initially used as pesticides
It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.
It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.
It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures
It contained toxins: It contains moderate toxins.
I’m pretty sure it is Synchondrosis

FiRsT PaRt of The QuEsTiOn:
The Risks of Modern agricultural practices are-
contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
The benefits of Modern Agricultural practices are-
An increase in yield of primary crops and lower food prices is as the result of modern technology like new crop varieties, the use of big data and precision agriculture.
Modern machinery like tractors and threshers when used up in farming make ploughing and harvesting faster.
SeCoNd PaRt Of ThE QuEsTioN:
No, I don't think the Benefits outweigh the RISKS of hurting the nature because we are compromising the needs of the future for more yield of crops. Modern practices may give you faster results but it takes away the fertility of the soil instead, It makes the land infertile. After using these modern practices you may not even have the land to do agriculture with.
