ANSWERS
1: removing invasive species
2: decreased oxygen in the water
3: changes in farming practices such as draining wetlands and pesticide use
4: fire
5: increase in plankton
The first 2 are wrong the rest are right
1: removing invasive species
2:decreased oxygen in the water
This is right for Connexus science 6B:human activity and change
Unit 3 lesson 8
Hope this help’s < 3
Connexus Girl is right thanks!
Yeah you are so right! LOL 🤣🤣🤣
did yall not have a test../!?!
@Conexxus girl is the one to go to. Has the correct answers for the Human Activity and Change Quick Check unit 8 lesson 8, your welcome.
P.S. sub to me @Cartooni on yt
Connexus Girl is right
1) To check the answer to question 1, you need to consider which activity out of the options mentioned would reduce habitat loss. Let's evaluate each option:
A) Replacing golf courses with farms may actually contribute to habitat loss because it involves converting natural areas into agricultural land.
B) Draining a wetland to plant fruit trees would lead to habitat loss as wetlands are important ecosystems.
C) Removing invasive species can help restore the natural balance of an ecosystem, but it may not directly reduce habitat loss.
D) Spreading out the human population can help reduce habitat loss as it can decrease the extent of urbanization and encroachment into natural habitats.
From the given options, it appears that option D, spreading out the human population, is the most reasonable choice for reducing habitat loss. Therefore, it seems like the correct answer is D.
2) For question 2, you need to determine what effect algae blooms have on ocean ecosystems. Let's analyze the options:
A) Increased underwater plant population is unlikely since algae blooms primarily consist of algae and not other types of plants.
B) Increased fish population is also unlikely because extensive algae blooms can lead to oxygen depletion and harm fish populations.
C) Decreased carbon dioxide in the water is incorrect as algae blooms can actually increase carbon dioxide levels due to the decomposition of excessive algae.
D) Decreased oxygen in the water is the most plausible effect of algae blooms since they consume oxygen during decomposition and can lead to low oxygen levels.
Based on the options given, it seems that option D, decreased oxygen in the water, is the most accurate effect of algae blooms on ocean ecosystems. Therefore, it appears that the correct answer is D.
3) To examine the answer to question 3, you must understand the primary factor researchers think is responsible for the decrease in North American bird populations. Let's look at the options:
A) Decreased hunting of predator species does not directly explain the decrease in bird populations.
B) Changes in farming practices such as draining wetlands and pesticide use can lead to habitat loss and pollution, which can negatively impact bird populations.
C) Recreational hunting of bird species such as waterfowl may be a contributing factor, but it is not considered a primary factor.
D) A decrease in conservation efforts may contribute to the decline, but it is not the primary factor being discussed.
Considering the options provided, it appears that option B, changes in farming practices such as draining wetlands and pesticide use, is the most plausible primary factor in the decrease of North American bird populations. Therefore, the correct answer seems to be B.
4) For question 4, you need to identify the abiotic event that benefits lodgepole pine trees. Let's evaluate the options:
A) A flood is unlikely to benefit lodgepole pine trees because excessive water can lead to root rot and other detrimental effects.
B) Fire is the correct answer because lodgepole pine tree cones release their seeds in response to heat from a fire.
C) A tornado is not relevant to the specific reproductive mechanism of lodgepole pine trees.
D) A drought would not directly benefit lodgepole pine trees as they require sufficient moisture to grow and reproduce.
Based on the options, it appears that option B, fire, is the abiotic event that benefits lodgepole pine trees. Therefore, it seems like the correct answer is B.
5) To check the answer for question 5, you need to consider which change would benefit jellyfish. Let's analyze the options:
A) An increase in tuna is unlikely to benefit jellyfish since tuna prey on jellyfish.
B) An increase in plankton is the most logical option because jellyfish compete with anchovies for plankton as a food source.
C) An increase in swordfish may not directly benefit jellyfish as they are predators of jellyfish.
D) An increase in anchovies may negatively affect jellyfish as they compete for the same food source (plankton).
Considering the options provided, it appears that option B, an increase in plankton, is the change that would likely benefit jellyfish. Therefore, it seems like the correct answer is B.
I hope this helps you check your answers effectively! Let me know if you have any more questions.
I agree with all your answers. Just make sure we are not cheating or we will have to kick you off this site. Thank you!
Also try to make sure you explain why you said your answers with text evidence. This will make it so that kids will understand why you chose that answer.
Thank you and have a good day!
