A decrease in rainfall in a tropical rainforest might be a limiting factor for animals and plans living there.  

• True
• False

The largest number of individuals of a population that the environment can support is called the...

• carrying capacity
• limiting factor
• exponential growth
• biodiversity

What is the carrying capacity of the graph?

• around 500
• more than 500
• less than 500
• around 600

Limiting factors are sometimes helpful because they can keep the population from getting to large.

• True
• False

Will competition increase/decrease the carrying capacity of an ecosystem for the animal in competition?

• Decrease
• Increase

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow
• The population starts to die off to return to carrying capcity
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity
