28
Q

It refers to the unsustainable use or harvesting of natural resources

A

Biodiversity Exploitation

29
Q

Any form of abuse of flora and fauna threatens biodiversity.

A

Biodiversity Exploitation

30
Q

_________ may threaten their proliferation. Gathering these endangered ones for trading is an act punishable by law.

A

Overexploitation

31
Q

This poses the greatest threat to biodiversity.

A

Overpopulation

32
Q

As the population increases, the demand for all human needs and wants also increases. As demand increases, the need for our natural resources also increases. We are at the point where we get too much from the environment but do not contribute to its replacement

A

Overpopulation

33
Q

This can be prevented through appropriate research, government legislation, education and awareness, and sustainable use of biodiversity.

A

Diversity Loss

34
Q

There are very few researches that focus on the biodiversity of various organisms.

A

Conserving Biodiversity

35
Q

The sustainable use of biodiversity should be given emphasis.

A

Conserving Biodiversity

36
Q

Education and awareness activities have started and are being done continuously. Community-based programs are also initiated to help conserve biodiversity. People involve themselves in conservation projects.

A

Conversing Biodiversity

37
Q

Implementation of laws and orders to save biodiversity. These laws never forget preserving the wellness and betterment of our nature.

A

Conversing Biodiversity

38
Q

It is how the genetic composition of species changes over time.

A

Evolution

39
Q

Evolution may be ____________ or a ____________.

A

Microevolution
Macroevolution

40
Q

It is the evolution between species levels

A

Microevolution

41
Q

It is the type of evolution that gives rise to new species or larger groups, such as new genera, families, classes, or phyla.

A

Macroevolution

42
Q

It may happen through artificial selection or natural selection.

A

Evolution

43
Q

A

Artificial Selection

44
Q

the environment determines which organisms survive and perpetuate.

A

Natural Selection

45
Q

By ____________, individuals vary, and variations could be inherited. The variations may confer advantages on the next generation so that the individual have better capacity to adapt and survive.

A

Natural Selection

46
Q

is the dying out or termination of a species.

A

Extinction

47
Q

This occurs due to environmental forces like climate change, habitat fragmentation, and overexploitation, or because of evolutionary changes in their members like inbreeding, poor reproduction, superior competition, and a decline in the population.

Ozone Depletion

52
Q

is a global agreement that addresses the destruction of the ozone layer.

A

The Montreal Protocol

54
Q

refers to the rise in Earth’s temperature.

A

Global Warming

55
Q

It is primarily caused by human activities, specifically the burning of fossil fuels.

57
Q

Burning ________ generates the energy needed for vehicles, houses, and businesses.

A

Fossil Fuels

58
Q

Using _______ releases a large amount of carbon, which contributes to the heat-trapping gases present in the atmosphere.

A

Fossil Fuels

59
Q

Increasing greenhouse gases will lead to global warming, and global warming will result in __________.

A

Climate Change

60
Q

It describes the long-term changes in climate due to continuous warming of the Earth.

A

Climate Change

61
Q

This involves the use of nuclear weapons, which will cause radiation contamination

A

Nuclear Wars

62
Q

This may affect thousands of people, resulting in cancer, birth defects for pregnant individuals, and ARS

A

Nuclear Wars

63
Q

What is the meaning of ARS

A

Acute Radiation Syndrome

64
Q

It also destroys infrastructure and may contaminate an ecosystem for a long period of time.

A

Nuclear War and Nuclear Contamination

65
Q

The use of petroleum-based fertilizer may lead to ________.

A

Euthrophication

66
Q

is a process that occurs in bodies of water because of the increasing nutrients (such as nitrogen and phosphorus) that stimulate the growth of algae and result in oxygen depletion. Since aquatic organisms also need oxygen in order to breathe, other organisms that live in the water end up dying because of too much algae.

A

Euthrophication
