Ecology Quiz

The maximum number of individuals of a species that an environment can support indefinitely is known as:

• Carrying Capacity

• Population Density

• Logistic Growth

• Exponential Growth

Logistic growth in a population occurs when:

• Resources are unlimited

• Population growth is rapid and unchecked

• Population growth slows as it approaches carrying capacity

• Predators are introduced into the ecosystem

What is a population?

• Different species living in the same area

• Same species living in the same area

• All living things and their abiotic factors in an area

• All non-living things in an area

As a population approaches its carrying capacity, which of the following is most likely to occur?

• Birth rate increases

• Death rate decreases

• Immigration rate increases

• Competition increases

Which of the following is NOT a density-dependent limiting factor?

• Competition

• Parasitism

• Natural Disasters

• Herbivory

Which property of water arises due to its unequal sharing of electrons between hydrogen and oxygen atoms?

• High heat capacity

• Low density as a solid

• Polarity

• Surface Tension

Which property of water allows it to form droplets on a leaf?

• Polarity

• Surface Tension

• Density

• High heat capacity

What property of water allows it to moderate temperature changes on Earth?

• High specific heat capacity

• Low density as a solid

• High heat of vaporization

• High cohesion

What is the pH of water?

• 10

• 3

• 14

• 7

Which property of water allows it to climb up a thin glass tube, such as a plant stem?

• Heat Capacity

• Capillary Action

• Density

• Polarity
