Environmental Science Quiz

Ecological Concepts

• Alpha diversity primarily refers to the diversity of species within a particular ecosystem or region.

Environmental Factors

• Deforestation leads to a decrease in biodiversity.

Air Pollution

• The main component responsible for the formation of photochemical smog is nitrogen oxides.
• Photochemical smog is also formed by the presence of volatile organic compounds (VOCs).
• The primary cause of photochemical smog is the reaction between nitrogen oxides and VOCs in the presence of sunlight.

Biodiversity

• The main implication of having biodiversity hotspots around the world is that these areas are rich in endemic species and are under threat from habitat destruction and other human activities.

Water Pollution

• The primary cause of eutrophication in water bodies is the excessive amount of nutrients, particularly phosphorus and nitrogen, from human activities such as agricultural runoff and sewage.

Marine Ecosystems

• Coral bleaching signifies the expulsion of algal symbionts by coral reefs due to stress caused by rising water temperatures, leading to the loss of coral reefs and the associated ecosystem.

Air Pollution Control

• The absorption technique is used to control gaseous pollutants by capturing and separating them from the air using an adsorbent material.

Climate Change

• Carbon dioxide is the largest contributor to global warming.
• A carbon credit represents the right to emit one ton of carbon dioxide or other greenhouse gases, and is used as a mechanism to reduce greenhouse gas emissions and mitigate climate change.
