Eutrophication is a _____.

  1. Neutral sign for ecosystem

  2. Dual-sided sign for ecosystem

  3. Bad sign for ecosystem

  4. Good sign for ecosystem

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

Arsenic is an example of _____.

  1. Organic waste

  2. Inorganic waste

  3. Acid

  4. Base

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wastes which consist of materials those are difficult to biodegrade so that destruction takes a very long time are known as inorganic wastes. Inorganic wastes come from non renewable natural resources such as minerals and petroleum, or from industrial processes. Some inorganic wastes as a whole cannot be explained by nature, while others can only be described in a very long time.

Examples of inorganic wastes- chemical solvents, paints, sandpaper, paper products, industrial by-products, metals, and radioactive wastes, sand, salt, Iron, Calcium and other mineral materials like  Arsenic.

Problem of solid waste disposal can be reduced through _____.

  1. Recycling

  2. Lesser pollution

  3. Population control

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Recycling is the process of converting waste materials into new materials and objects. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. Recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing: energy usage, air pollution (from incineration), and water pollution.

  2. BOD

  3. Dioxins

  4. Greenhouse effect

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dioxins are a group of dangerous chemicals which are known as persistent organic pollutants. Dioxins are found throughout the world in the environment. They accumulate in the food chain, mainly in the fatty tissue of animals. Dioxins are highly toxic. They can cause reproductive and developmental problems. They can cause physical and mental abnormality. They can damage the immune system. They can interfere with hormones and also cause cancer.
