1.
Places in nature without people.
Correct Answer
A. Wilderness
Explanation
The term "wilderness" refers to places in nature that are devoid of human presence or habitation. It typically describes remote, untouched areas that are undisturbed by human activity. These areas can include forests, mountains, deserts, and other natural landscapes. The answer "wilderness" accurately captures the concept of places in nature without people as it encompasses the idea of untouched and uninhabited environments.
2.
World wide rise in Earth's average temperature.
Correct Answer
C. Globar Warming
Explanation
The correct answer is "Global Warming." This refers to the worldwide increase in Earth's average temperature. It is caused by the greenhouse effect, where certain gases in the atmosphere trap heat and prevent it from escaping into space. This leads to a rise in global temperatures, which can have various impacts on the environment, such as melting ice caps, rising sea levels, and changes in weather patterns.
3.
Rock like structure built by tiny sea animals.
Correct Answer
coral reef
Explanation
A coral reef is a rock-like structure that is built by tiny sea animals called coral polyps. These polyps secrete calcium carbonate to form a hard skeleton that provides a foundation for the reef. Over time, the accumulation of these skeletons creates a complex and diverse ecosystem known as a coral reef. Coral reefs are found in warm, shallow waters and are home to a wide variety of marine life. They are important for coastal protection, as well as for tourism and fishing industries.
4.
Place where a plant or animal lives.
Correct Answer
habitat
Explanation
The term "habitat" refers to the specific place or environment where a plant or animal naturally lives or grows. It encompasses all the physical, biological, and environmental factors that are essential for the survival and reproduction of a particular species. A habitat provides the necessary resources, such as food, water, shelter, and suitable conditions, for the organisms to thrive and fulfill their ecological roles. It is the unique combination of abiotic and biotic factors that determines the characteristics and diversity of different habitats around the world.
5.
Animals that eat other animals.
Correct Answer
B. Predator
Explanation
Animals that eat other animals are referred to as predators. Predators are organisms that hunt and kill other organisms for food. They are typically higher up in the food chain and have adaptations that allow them to capture and consume their prey. Predators play a crucial role in maintaining the balance of ecosystems by controlling the population of their prey species. Examples of predators include lions, wolves, and sharks.
6.
An animal that is eaten by another animal.
Correct Answer
D. Prey
Explanation
The correct answer is "Prey." Prey refers to an animal that is hunted and consumed by another animal. It is the target of a predator's feeding behavior. In this context, lunch and dinner are not specific to animals being consumed, while predator refers to the animal doing the hunting rather than being hunted. Prey is the most suitable term to describe an animal being eaten by another animal.
7.
People who fight fires.
Correct Answer
firefighter
Explanation
A firefighter is a person who fights fires. They are trained professionals who respond to emergencies involving fires and work to extinguish them, rescue people and animals, and protect property. Firefighters are equipped with specialized gear and tools to safely combat fires and are often part of a fire department or emergency response team.
8.
A firefighter who jumps from a plane to reach and fight wildfires.
Correct Answer
smoke jumper
Explanation
A smoke jumper is a firefighter who is specially trained to parachute from a plane into remote areas to combat wildfires. They are equipped with the necessary gear and tools to suppress and control the fires. This method allows them to quickly reach areas that are difficult to access by ground, enabling them to contain and extinguish the fires more effectively. Smoke jumpers play a crucial role in firefighting, especially in rugged and inaccessible terrain.
9.
Name three things that a fire needs.
Correct Answer
heat, oxygen, fuel
Explanation
Fire needs three things to sustain: heat, oxygen, and fuel. Heat is the initial ignition source that raises the temperature of the fuel to its ignition point. Oxygen is necessary for the combustion process as it supports the chemical reaction between the fuel and heat. Fuel refers to any combustible material that can sustain the fire, such as wood, paper, or gasoline. Without any of these three elements, a fire cannot start or continue burning.
10.
Three things that a fire needs.
Correct Answer
C. Fire triangle
Explanation
The fire triangle is a concept used to explain the three elements necessary for a fire to occur: fuel, heat, and oxygen. Without any one of these elements, a fire cannot sustain itself. Fuel provides the material to burn, heat raises the temperature of the fuel to its ignition point, and oxygen supports the combustion process. Therefore, the fire triangle represents the interdependence of these three elements in the fire triangle.
