Question 1 A)Which of the following events would decrease competition for resources in an ecosystem?(1 point) Responses many offspring are produced in a single year many offspring are produced in a single year a disease reduces the population of rabbits in a grassland area a disease reduces the population of rabbits in a grassland area a drought reduces the amount of water available to an ecosystem a drought reduces the amount of water available to an ecosystem a fire has killed off a portion of the vegetation a fire has killed off a portion of the vegetation Question 2 A)Which competition is exclusively intraspecific?(1 point) Responses competition for shelter competition for shelter competition for mates competition for mates competition for food competition for food competition for water competition for water Question 3 A)Which of the following best explains the connection between increased competition and the evolution of a species by natural selection?(1 point) Responses Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem. Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem. Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation. Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation. Individuals that have traits that allow them to outcompete others survive better and produce more offspring. Individuals that have traits that allow them to outcompete others survive better and produce more offspring. Individuals that must compete for limited resources are more likely to have diseases that cause mutations. Individuals that must compete for limited resources are more likely to have diseases that cause mutations. Question 4 A)Which of the following best explains the phrase “survival of the fittest” in terms of evolution by natural selection?(1 point) Responses The individuals that are the healthiest will always get more resources and survive better. The individuals that are the healthiest will always get more resources and survive better. The strongest and fastest individuals will always survive and reproduce more often. The strongest and fastest individuals will always survive and reproduce more often. The individuals that survive better and reproduce more often will pass their traits on more often. The individuals that survive better and reproduce more often will pass their traits on more often. Only individuals that have the most mates will survive with limited resources. Only individuals that have the most mates will survive with limited resources. Question 5 A)Which statement about natural selection is true?(1 point) Responses Natural selection produces animals that are faster and stronger. Natural selection produces animals that are faster and stronger. Natural selection produces animals fit for their environment. Natural selection produces animals fit for their environment. Natural selection only happens to animals. Natural selection only happens to animals. Evolution causes natural selection.
Natural selection produces animals fit for their environment.
answer all questions
1) A drought reduces the amount of water available to an ecosystem would decrease competition for resources in an ecosystem.
2) Competition for mates is exclusively intraspecific.
3) Individuals that have traits that allow them to outcompete others survive better and produce more offspring best explains the connection between increased competition and the evolution of a species by natural selection.
4) The individuals that survive better and reproduce more often will pass their traits on more often best explains the phrase "survival of the fittest" in terms of evolution by natural selection.
5) Natural selection produces animals fit for their environment is a true statement about natural selection.
