Grade 5- Ecology

In any population there will be individuals with traits that give them an advantage over others in the population and are more likely to survive and reproduce. This is part of which principle?

• carrying capacity

• natural selection
• genetic resistance
• translation

The non-living part of an ecosystem

• Ocean
• Lava Flow
• Birds
• Abiotic

Two or more members of a particular species living and interacting in the same area

• Community
• Population
• Organisms
• Biosphere

Different populations living and interacting with each other in the same area

• Biome
• Ecosystem
• Community
• Niche

What happens if a population grows past its carrying capacity?

• The population keeps growing

• The population starts to die off

• The entire species will go extinct

• The carrying capacity just increases

This may cause a population to increase

• increase of food supply

• removal of predators

• removal of disease

• all of these

The largest number of individuals that an environment can support long term is...

• carrying capacity

• emigration

• immigration

• population density

Something that regulates the size of a population is called...

• a limiting measure

• a limiting factor

• carrying capacity

• biodiversity

What are factors that affect carrying capacity?

• Biotic only

• Biotic and abiotic

• Depends on the ecosystem

• Abiotic only

What is the carrying capacity of the graph?

• 1000

• 8000

• 800

• 600
