Adapting to Change How Environmental Shifts Impact Organisms and Ecosystems

The video discusses how organisms adapt to short and long term environmental changes. Short term changes, like natural disasters, have immediate effects, while long term changes, often caused by human activities, occur gradually. These changes impact ecosystems, affecting the survival and reproduction of species. Long term changes may lead to genetic variations and natural selection, allowing some species to adapt and survive. If species cannot adapt or relocate, they risk extinction.

What is the primary focus of the video presented by Mr. Lara?

• The benefits of urbanization

• The history of climate change

• How environmental changes affect organisms and populations

• The impact of technology on education

Which of the following is an example of a short-term environmental change?

• Global warming

• Hurricanes

• Introduction of new species

• Deforestation

What is the effect of short-term environmental changes on ecosystems?

• They only affect abiotic factors

• They have no effect

• They cause immediate changes and can lead to extinction

• They improve ecosystem stability

What is a characteristic of long-term environmental changes?

• They occur suddenly and unexpectedly

• They have immediate effects on ecosystems

• They happen over a longer period and can alter ecosystems significantly

• They are always caused by natural disasters

How do long-term environmental changes affect the survival of species?

• They force immediate extinction

• They only affect abiotic factors

• They provide time for adaptation or relocation

• They have no impact on species survival

Which human activity is NOT mentioned as a cause of long-term environmental changes?

• Space exploration

• Agriculture

• Pollution

• Urbanization

What process allows populations to adapt to long-term environmental changes?

• Genetic mutation

• Natural selection

• Random chance

• Artificial selection

What happens if populations do not adapt to long-term environmental changes?

• They remain unaffected

• They become extinct

• They migrate to urban areas

• They thrive and increase in number

Which of the following is NOT a result of long-term environmental changes?

• Genetic variations in populations

• Changes in population density

• Relocation of species

• Immediate extinction of species

Which factor is NOT affected by long-term environmental changes?

• Abiotic factors

• Genetic makeup of populations

• Biotic factors

• The color of the sky
