Question 1
Points: 1
what is the definition of "energy"?
Explanation
According to the text, "Energy is the ability to perform work or change something."
Question 2
Points: 1
What are the tiny openings on the underside of most leaves that allow air to enter and can close to prevent water from escaping?
Explanation
The text states that "Tiny openings on the underside of most leaves allow air to enter. These openings-called stomata-can close and prevent water from escaping."
Question 3
Points: 1
Water is absorbed by a plant's roots and travels up the center of the stem through specialized tissues called:
Explanation
The text mentions, "Water is absorbed by a plant's roots. It travels up the center of the stem through specialized tissues called xylem."
Question 4
Points: 1
what are the primary roles of a plant's leaves regarding the flow of energy and air?
Explanation
Leaves are the primary sites for photosynthesis, where they capture sunlight, absorb carbon dioxide, and release oxygen.
Question 5
Points: 1
Which plant structure is responsible for taking in water and nutrients from the soil?
Explanation
The text states, "Water is absorbed by a plant's roots."
Question 6
Points: 1
Why do plants need enough space where they grow?
Explanation
The text states, "Plants need enough space where they grow for their roots to spread out and absorb water and nutrients from the soil."
Question 7
Points: 1
In the presence of light energy, water and carbon dioxide combine to produce:
Explanation
The text explains, "Water and carbon dioxide combine in the presence of light energy to produce sugar and oxygen."
Question 8
Points: 1
Where is the energy from the sunlight contained after the plant makes its food?
Explanation
The text states, "Energy from the sunlight is now contained in the sugars. The sugars are what the plant uses for food."
Question 9
Points: 1
Which specialized tissues are responsible for transporting sugars to all parts of the plant?
Explanation
The text clearly defines, "Phloem are tissues that transport sugars to all parts of the plant."
Question 10
Points: 1
What is "transpiration" based on the text?
Explanation
The text defines, "Transpiration is the evaporation of water from a plant's leaves."
Question 11
Points: 1
As water evaporates from the leaves during transpiration, how does water move within the plant?
Explanation
The text states, "As water evaporates from the leaves, more water is carried from the bottom of the plant to the top."
Question 12
Points: 1
Why would it be a disadvantage if plants grow too close together?
Explanation
When plants grow too close, they compete for essential resources like light, water, and nutrients from the soil, which are crucial for their survival and growth.
Question 13
Points: 1
Some woody vines can grow on rainforest trees and climb high into the tree canopy. Why would this be an advantage for the vines?
Explanation
In dense rainforests, sunlight is a limited resource on the forest floor. Climbing into the canopy allows vines to access more sunlight for photosynthesis and growth.
Question 14
Points: 1
what is a "predator"?
Explanation
The text states, "Organisms that hunt for their food are predators."
Question 15
Points: 1
What is the definition of "prey"
Explanation
The text states, "The organisms they hunt are prey."
Question 16
Points: 1
Why are predators important in an ecosystem?
Explanation
The text mentions, "Predators are important in ecosystems because they help control the size of prey populations."
Question 17
Points: 1
When the populations of prey are controlled by predators, what is the direct benefit to the ecosystem?
Explanation
The text states, "When the populations of prey are controlled, producers and other resources are less likely to run out."
Question 18
Points: 1
Match the terms based on their definitions in the text: Herbivores eat plants. Carnivores eat other animals. Omnivores eat both plants and animals. Which of the following correctly pairs an animal type with its food source?
Explanation
The provided definitions state that "Carnivores eat other animals."
Question 19
Points: 1
what is the definition of "decomposers"?
Explanation
The text defines decomposers as "Organisms that turn this material into simpler substances."
Question 20
Points: 1
What type of organism is bacteria,
Explanation
The text states, "Bacteria are a type of organism made up of a single cell."
Question 21
Points: 1
Why did scientists think fungi were plants for many years?
Explanation
The text explains, "For many years, scientists thought fungi were plants because they didn't move and many sprouted from soil."
Question 22
Points: 1
Unlike plants, fungi cannot:
Explanation
The text explicitly states, "Unlike plants, however, fungi cannot make their own food."
Question 23
Points: 1
What is considered the most important role of decomposers in an ecosystem?
Explanation
The text highlights, "Making nutrients available to plants is the most important role of decomposers in an ecosystem."
Question 24
Points: 1
how do the bacteria living on the roots of plants interact with the atmosphere?
Explanation
The text in the image caption (page 16) states, "The bacteria that live on the roots of plants change nitrogen gas into a form plants can use."
