The end product of adaptation is:

• Effervescence

• Evasion

• Extinction

• Evolution

Main reason for great biodiversity on Earth?

• Many habitats

• One sphere

• Gravitational force

• Lunat influence

Extinction can occur due to:

• Natural factors

• Unnatural factors

• Density dependent factors

• Density independent factors

Adaptations are generally:

• Behavioural

• Seasonal

• Physical

• Cellular

The end result of an adaptation that lead to evolution is:

• a new community

• a new population

• a new specie

• a new habitat

When organisms go extinct:

• there is a niche that needs to be filled

• there is a full moon and a change in habitat

• there is more stability in the ecosystem

• there are fewer chances for climate change
