Questions and Answers

1.

A/ an _______________ is a group of living and nonliving things that work together in one environment like in a rainforest or desert.

Explanation
An ecosystem refers to a complex network of living organisms, such as plants, animals, and microorganisms, along with their physical environment. It involves the interaction and interdependence of these organisms within a specific habitat, like a rainforest or desert. A community, on the other hand, refers to a group of different species living together in a particular area. A school, however, is a place of education and does not involve the interaction of living and nonliving things in an environment.

To be considered a desert, the rainfall total must be 10 inches of rain per year or less.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because the definition of a desert is an area that receives very little rainfall. In order for an area to be classified as a desert, it must have an annual rainfall total of 10 inches or less. This low amount of rainfall is what characterizes deserts and contributes to their arid and dry conditions.

Correct Answer(s)
A. The Forest Floor
C. The Canopy
D. The Understory
F. The Emergent Layer

Explanation
The correct answer includes the Forest Floor, Canopy, Understory, and Emergent Layer. These are the different layers that make up the rainforest ecosystem. The Forest Floor is the lowest layer, where decomposing plants and animals are found. The Canopy is the layer formed by the tops of the trees, which provides shade and shelter for many animals. The Understory is the layer beneath the canopy, consisting of smaller trees, shrubs, and plants. The Emergent Layer is the highest layer, consisting of the tallest trees that rise above the canopy.

- A.
  
  Wanderers
- B.
  
  Nomads
- C.
  
  Gila monsters
Correct Answer
B. Nomads

Explanation
Nomads are people who move from place to place as a means of livelihood. They often search for water and grazing land for their cattle. This lifestyle of constantly moving is a characteristic of nomadic communities, who rely on the availability of resources in different locations. The term "wanderers" could also be used to describe such people, but "nomads" specifically refers to individuals who have a nomadic way of life. "Gila monsters" are unrelated to the given context and do not fit the description of people who move for a living.

This is a trick of light and hot air that acts like a mirror reflecting water that is not really there.
- A.
  
  Mesa
- B.
  
  Oasis
- C.
  
  Mirage
Correct Answer
C. Mirage

Explanation
A mirage is a phenomenon caused by the refraction of light and the temperature gradient in the air. It creates an optical illusion that makes distant objects appear closer or creates the illusion of water or a pool of water on the ground. This occurs when light rays bend as they pass through layers of air with different temperatures, creating a false image that appears like a reflection of water. Therefore, the given explanation accurately describes the concept of a mirage.
