Question 1
Points: 1
When a species is considered "endangered" what does this mean?
Explanation
An endangered species is a type of organism that is at risk of extinction due to habitat loss, pollution, or other factors.
Question 2
Points: 1
Human activities partly cause species to become endangered through pollution in the form of litter and ___________.
Explanation
Acid rain and litter are common forms of human-caused pollution that damage ecosystems and threaten wildlife.
Question 3
Points: 1
Pollution such as litter and acid rain can especially harm which types of ecosystems that are home to a wide variety of organisms?
Explanation
Ocean ecosystems are highly sensitive to pollution like litter and acid rain, which can harm diverse marine life.
Question 4
Points: 1
Acid rain falling into ocean ecosystems severely harms marine living things. This destructive process shows a negative interaction between which two Earth systems?
Explanation
Acid rain (formed in the atmosphere) falls into the water (hydrosphere) and harms living organisms (biosphere).
Question 5
Points: 1
Invasive species can have a serious impact on the environment. What is a smart human choice mentioned to restore balance to Earth's systems without affecting the soil?
Explanation
Planting native species helps restore the natural balance of an ecosystem and supports local wildlife without introduced harm.
Question 6
Points: 1
Some species are highly likely to spread quickly and become invasive. What is the reason given in the text?
Explanation
Invasive species often lack natural predators in a new environment, allowing their populations to grow unchecked.
Question 7
Points: 1
What are the three main areas that an invasive species can harm?
Explanation
Invasive species cause ecological damage, financial loss in industries like agriculture, and can spread diseases.
Question 8
Points: 1
Looking at the evidence provided about the cane toad in Australia, which details explain why its population grew into the millions and became invasive?
Explanation
The cane toad's toxicity prevents native predators from eating them, leading to a massive population surge.
Question 9
Points: 1
What is an "ecosystem" made up of?
Explanation
An ecosystem includes all biotic (living) and abiotic (nonliving) components interacting in a specific environment.
Question 10
Points: 1
What are "biotic factors"?
Explanation
Biotic factors refer specifically to the living components of an ecosystem, such as plants, animals, and bacteria.
Question 11
Points: 1
Which of the following groups contains only "biotic factors"?
Explanation
Plants, animals, fungi, and bacteria are all living organisms, therefore they are biotic factors.
Question 12
Points: 1
How are "abiotic factors" defined?
Explanation
Abiotic factors are the nonliving physical and chemical parts of the environment that affect living organisms.
Question 13
Points: 1
Which of the following is a list of "abiotic factors"?
Explanation
Air, water, soil, rocks, and light are all nonliving components of an environment.
Question 14
Points: 1
What is the relationship between biotic and abiotic factors in an environment?
Explanation
In an ecosystem, living things (biotic) depend on and interact with nonliving things (abiotic) to survive.
Question 15
Points: 1
How can changes on Earth affect the population of animals over time?
Explanation
Changes in environmental conditions impact the resources animals need, directly influencing their population size.
Question 16
Points: 1
What are three major factors that changes on Earth can affect, causing an animal's population to increase or decrease?
Explanation
Survival of animal populations depends on the availability of essential resources like food, water, and shelter.
Question 17
Points: 1
Why are the golden toad and the whitefin dolphin considered extinct?
Explanation
Extinction means that there are no remaining individuals of a species left on Earth.
Question 18
Points: 1
Which animal population is actively protected and able to grow?
Explanation
According to the text provided, the mountain gorilla is an example of an animal population that is growing due to protection efforts.
