Organism and Environments

The largest group of organisms found in a food web would be:

• Primary Consumers
• Producers
• Decomposers
• Tertiary Consumers

What may happen if the snowshoe hare was removed from the food web pictured?

• The insects in the habitat would increase.
• The shrew population would decrease due to being only hawk food source.
• The willow tree population would decrease.
• Foxes would dies due to no food source. 

The rabbit in this food web would be considered a:

• Decomposer
• Producer
• Secondary Consumer
• Primary Consumer

The fox in this food web would be considered a:

• Tertiary Consumer
• Producer
• Secondary Consumer
• Primary Consumer

• Grasshopper

• Frog

• Snake

• Eagle

What is a possible effect of long-term environmental changes?

• adaptation

• migration

• habitat loss

• starvation

Which natural occurrence is an example of a long-term environmental change?

• Lightning sparks a forest fire.

• An earthquake results in a tsunami.

• A river floods due to a strong thunderstorm.

• The peppered moth evolves from a light to a dark color.

Which is one way that a short-term environmental change will most likely affect organisms within an ecosystem?

• It will lead to larger populations.

• It will lead to speciation.

• It will lead to adaptation.

• It will lead to forced migration.

When the Australian wildfires occurred, what short-term effect did the ecosystem experience?

• The trees grew back quick and the animals were not affected.

• There was no effect on the ecosystem.

• All of the plants died but the animal population increased.

• Plants and/or animals relocated or died.

How do the oceans contribute to the amount of Oxygen in the Earth's atmosphere?

• Fish in the ocean produce oxygen.

• Phytoplankton in the ocean produce oxygen through the process of respiration.

• Phytoplankton in the ocean produce oxygen through the process of photosynthesis.
