Question

1 multiple choice 1 point
in the united states, asian carp, asian honeysuckle, and kudzu are all examples of
commensalism
speciation
keystone species
invasive species
2 multiple choice 1 point
in a typical predator and prey relationship, when the prey population increases,
the predator population remains stable
the predator population increases
the predator population decreases
the predator population faces extinction
3 multiple choice 1 point
an organism that feeds off another without immediately killing it is a
parasite
mutualist
mimic
commensal
4 multiple choice 1 point
what can one infer from a relatively linear survivorship curve, and what organism generally exhibits this kind of survivorship curve?
none of these examples fit a linear curve
the mortality rate is roughly uniform across the lifespan of this organism; birds
the mortality rate is higher for older members of this population; humans
the mortality rate is higher for younger members of this population; oak trees

Explanation:

1. Invasive species are non - native organisms that cause harm to the environment, economy, or human health. Asian carp, Asian honeysuckle, and kudzu are non - native to the US and have negative impacts, so they are invasive species.
2. In a predator - prey relationship, when prey population increases, there is more food for predators. This leads to an increase in the predator population as more predators can survive and reproduce.
3. A parasite feeds off another organism (the host) without immediately killing it. A mutualist has a mutually beneficial relationship, a mimic resembles another organism, and a commensal has a relationship where one benefits and the other is not affected.
4. A relatively linear survivorship curve indicates a roughly uniform mortality rate across the lifespan. Birds generally exhibit this type of curve. Humans have a Type I curve (low mortality early, high later) and oak trees have a Type III curve (high mortality early, low later).

Answer:

1. Invasive species
2. the predator population increases
3. parasite
4. the mortality rate is roughly uniform across the lifespan of this organism; birds
