Science For Class 5 Questions and Answers
- 1.
What is the source of energy for producers?
- A.
The Earth
- B.
The wind
- C.
The Sun
- D.
Water
Correct Answer
C. The SunExplanation
Producers, also known as autotrophs, are organisms that can produce their own food through photosynthesis. The process of photosynthesis requires energy, which is obtained from the Sun. The Sun serves as the ultimate source of energy for producers, as it provides the light energy necessary for photosynthesis to occur. Therefore, the correct answer is "The Sun."Rate this question:

What kind of organism comes last in every food chain?
- A.
Omnivores
- B.
Consumers
- C.
Producers
- D.
Decomposers
Correct Answer
D. DecomposersExplanation
Decomposers come last in every food chain because they break down dead organic matter and recycle nutrients back into the ecosystem. They play a crucial role in the food chain by breaking down the remains of plants and animals, returning essential nutrients to the soil or water. This process allows for the continued growth of producers, which are then consumed by consumers, and the cycle repeats. Decomposers are essential for maintaining the balance and sustainability of ecosystems.Rate this question:

Transpiration is a process in plants that is responsible for:
- A.
Making of food
- B.
Making of water
- C.
Releasing the water
- D.
Losing food
Correct Answer
C. Releasing the waterExplanation
Transpiration is the process in plants where water is released from the leaves through small openings called stomata. This water loss occurs due to the evaporation of water from the leaf surface. Transpiration helps in maintaining the water balance in plants and plays a crucial role in the movement of water from the roots to the leaves. It also aids in cooling the plant and facilitating the uptake of nutrients. Therefore, the correct answer is "Releasing the water".Rate this question:

When a plant performs the process of photosynthesis, what substance is produced?
- A.
Carbon dioxide
- B.
Nitrogen
- C.
Oxygen and Glucose
- D.
Green pigment
Correct Answer
C. Oxygen and GlucoseExplanation
During the process of photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen. Oxygen is produced as a byproduct of photosynthesis and is released into the atmosphere. This oxygen is essential for the survival of many organisms, including humans, as it is needed for respiration. Therefore, the correct answer is oxygen and glucose.Rate this question:

Plants are also called:
- A.
Consumers
- B.
Producers
- C.
Herbivores
- D.
Decomposers
Correct Answer
B. ProducersExplanation
Plants are called producers because they have the ability to produce their own food through the process of photosynthesis. They convert sunlight, water, and carbon dioxide into glucose and oxygen, which is a fundamental process for sustaining life on Earth. Unlike consumers, which obtain energy by consuming other organisms, and decomposers, which break down dead organic matter, plants are unique in their ability to synthesize their own food, making them the primary source of energy in most ecosystems.Rate this question:

A food web is:
- A.
A web made out of food
- B.
A spider's eating habits
- C.
Inter lapping food chains
- D.
A spider's home
Correct Answer
C. Inter lapping food chainsExplanation
A food web refers to the interconnected feeding relationships between different organisms in an ecosystem. It consists of multiple food chains that overlap and interact with each other. Each food chain represents a series of organisms where one organism is eaten by another, forming a relatively linear pathway of energy transfer. The concept of interlapping food chains emphasizes the complex and interconnected nature of these relationships within an ecosystem.Rate this question:

The correct order of the following sequence ( rabbit, fox, carrots, fungi) in a food chain would be:
- A.
Carrots, fox, rabbit, fungi
- B.
Fungi, rabbit, fox, carrot
- C.
Carrot, rabbit, fox, fungi
- D.
None of the above
Correct Answer
C. Carrot, rabbit, fox, fungiExplanation
In a food chain, the organisms are arranged in the order of how organisms derive energy. Carrots are a producer; they are at the bottom of the food chain and are eaten by herbivores.. Rabbits are herbivores and eat carrots, so they come after carrots in the sequence. Foxes are carnivores and eat rabbits, so they come after rabbits. Fungi are decomposers and break down dead organisms, so they come at the end of the food chain.Rate this question:

Nutrients are returned to the ecosystem by:
- A.
Decomposers
- B.
Producers
- C.
Consumers
- D.
Scavengers
Correct Answer
A. DecomposersExplanation
Decomposers play a vital role in returning nutrients to the ecosystem. They break down dead organisms and organic waste, releasing nutrients back into the environment. Through the process of decomposition, decomposers such as bacteria and fungi break down complex organic matter into simpler forms, which can then be utilized by producers (plants) to perform photosynthesis and produce food. This nutrient cycling is crucial for maintaining the balance and sustainability of the ecosystem.Rate this question:

Write the scientific term: A community of organisms living together is called an _______.
Correct Answer
ecosystemExplanation
An ecosystem refers to a community of organisms that live together in a specific area and interact with each other and their environment. It includes both living organisms, such as plants, animals, and microorganisms, as well as the non-living components, such as soil, water, and air. The interactions within an ecosystem are complex and involve processes like energy flow, nutrient cycling, and ecological relationships. By studying ecosystems, scientists gain insights into the interdependence of organisms and their environment, helping to understand the functioning and balance of natural systems.Rate this question:
- 10.
Write the scientific term: Flow of energy between organisms is called:
Correct Answer
trophic flow, energy flow, calorific flowExplanation
The scientific term for the flow of energy between organisms is called "trophic flow" or more commonly "energy flow." This concept is central to the study of ecosystems and describes how energy is transferred from one trophic level to another within an ecological community. The term is crucial in understanding food chains and food webs, where energy flow begins with primary producers (typically photosynthetic organisms like plants and algae) and moves up to various consumers (herbivores, carnivores, and omnivores).Rate this question:
