Community Ecology Practice

What is tolerance within the scope of ecology?

• The specific role an organism plays in its community
• The place an organism lives
• An organism’s ability to survive and reproduce under changing conditions
• The amount of energy an organism needs to survive

What is a generalist?

• An organism with a wide tolerance and niche
• An organism that only eats one type of food
• An organism that cannot adapt to changing habitats
• An organism with a narrow tolerance

Which of the following is not a type of interaction between species?

• Competition
• Predation
• Herbivory
• Migration
• Symbiosis

Which of the following is an example of intraspecific competition?

• A lion and hyena fighting over prey
• White oak trees growing close together and fighting for sunlight
• A wolf hunting a rabbit
• An owl and a hawk hunting in the same area

What is a fundamental niche?

• The full range of conditions a species could use excluding the influence of predators
• The part of a niche an organism actually occupies due to competition
• An organism’s full niche without competition
• The habitat where an organism lives

How does resource partitioning allow species to coexist?

• By separating species into different habitats
• By eliminating one species completely due to intense competition
• By increasing predator populations to regulate population sizes
• By allowing species to use resources in different ways

What is predation?

• Two species sharing resources
• One organism hunting and killing another
• One organism benefitting while the other is unaffected
• An herbivore consuming a plant

How do predator and prey populations influence each other?

• Prey numbers rise when predator numbers drop
• Predator numbers drop when prey numbers increase
• Predator numbers are not influenced by prey numbers
• Prey numbers rarely change

What is herbivory?

• An animal eating a plant
• A plant eating an animal (ex. Venus fly trap)
• Two plants competing for sunlight
• A decomposer breaking down dead plants

Which of the following is an example of a symbiotic relationship?

• A lion hunting and eating a zebra
• A bee pollinating a flower while collecting nectar
• A hawk catching and eating a mouse
• A deer grazing on grass in a meadow
• A wolf challenging a coyote for food
