What is an example of how organisms respond to short term changes in the environment?

• Animals tend to eat a lot more.

• Animals will hibernate.

• Animals must be able to adapt to a new environment.

• Animals will go extinct or die due to the short term change.

Natural Disasters such as, earthquakes, flooding, and volcanic eruptions can cause ...

• short term changes

• long term changes

What are a catastrophic events?

• Events that are naturally occurring such as pollution and smog. These are generally bad for the environment but are necessary for evolution.

• Events that occur naturally such as flooding, deforestation, and land-slide. These change the shape of the land which is better for the environment.

• Occurrences caused by human made changes that affect the environment. These changes are generally good for the environment and can improve the biodiversity of a habitat.

• Natural occurrences that generally have a negative effect on people and or the environment that is affects. These events can cause damage to the shape of the land and to the lives of the people and other living organisms.

Animals that live in the frigid regions of the North or South Pole must adapt to special conditions. Which of these could be a helpful adaptation for an organism that lives in the North Pole?

• Ability to fly or run fast

• Large paws for hunting

• Thick fur and layers of fat

• Hard shell around the body

Some animals are adapted to survive harsh conditions. These animals drink very little and don't sweat. These adaptations make them well suited to what sort of environmental change?

• A steady decrease in temperature

• Earthquakes that create new landforms

• A long period of time with no rain

• The arrival of a new species of predator

A drought is a long period of time with little rainfall. What kind of adaptation would most help a plant survive a drought?

• Storing water

• Growing quickly

• Producing seeds

• Attracting insects

Which organ helps the fish to breath?

• GILLS

• FINS

• flippers

Individuals in a population that have the traits needed to survive in the environment get to survive and reproduce. Their offspring inherit those traits. Over time, a greater percentage of the population will have those successful traits.

• Natural selection

• Selective breeding

• Artificial selection

• Mutations

A mouse that is faced with environmental challenges, such as limited food, drought, and predators -

• Will either survive or die

• Can change its fur to be more camouflaged

• Can change the shape of its teeth to feed on different types of food

• Can begin migrating long distances in search of better habitat
