Global Warming

Question 1

Global Warming

Answer 1

Gradual increase in atmospheric temperature caused by increase in greenhouse gases

Question 2

Greenhouse gases

Answer 2

CO2, H2O, CH4 - required to trap heat

Question 3

Key species/keystone species

Answer 3

these species being removed triggers cascade effect

Question 5

Interdependency

Answer 5

Every living organism and its environment is affected by the presence/absence of biotic and abiotic components

Question 6

Eutrophication

Answer 6

When algal bloom is very high due to excess fertilization

Question 7

Biological oxygen demand

Answer 7

Algae dies and becomes feed for microorganisms - when mircoorganism population increases, the need for oxygen increases, oxygen level decreases

Question 8

Microplastics

Answer 8

Plastic doesn’t degrade, it breaks down into small particles under the presence of the sun

Question 9

Trophic transfer

Answer 9

When organisms that consume microplastics on one trophic level, predators that depend on them for food, consume them as well - affects organisms in all trophic levels

• aka bioaccumulation

Question 10

Conservation

Answer 10

• strict policies
• not giving policies to logging companies (monitor licensed companies)
• selective felling - selective cutting of trees in particular areas and leaving more trees to grow in the same area
• Coppicing - trees are chopped one meter above ground level, letting the tree have a chance to regrow

Question 11

Captive breeding

Answer 11

Breeding animals outside of their environments in restricted conditions in farms or other closed facilities
