Grade 5 Science Quiz

What are living organisms?

• Plants, animals, and humans

• Air, water, and rocks

• Producers, consumers, and decomposers

• Fungi, bacteria, and millipedes

Answer explanation

Living organisms are plants, animals, and humans. They are different from non-living things like air, water, and rocks. Living organisms can be classified into producers, consumers, and decomposers. However, in this case, the correct choice is plants, animals, and humans. They are the main types of living organisms that exist on Earth.

What is an ecosystem?

• An area that contains living organisms and nonliving things that interact with each other

• The process of decomposition by breaking down dead organisms

• A model that shows how energy passes from one organism to another

• The primary source of energy for all organisms on Earth

How does energy flow through an ecosystem?

• From plants to animals and between animals when they eat each other

• From the Sun to plants through photosynthesis

• From the environment to animals including humans

• From decomposers to producers

What happens to the energy of living organisms when they die?

• It is returned to the soil

• It is transferred to the Sun

• It is consumed by other living organisms

• It is converted into glucose sugar

Which of the following can attack hawks?

• Eagles

• Plants

• Worms

• Fungi

Answer explanation

Hawks can be attacked by eagles. This is because eagles are natural predators of hawks. The other options, such as plants, worms, and fungi, do not pose a threat to hawks. Eagles have the ability to hunt and capture hawks due to their superior strength and hunting skills. Therefore, eagles are the correct choice when it comes to attacking hawks.

What is the relationship between sunlight and the energy we get from our food?

• The energy we get from food originally comes from the Sun

• Sunlight is the primary source of energy for all organisms

• Sunlight is used by plants to make their own food

• Sunlight is converted into glucose sugar

What do we need energy for?

• All activities in our daily life such as thinking, breathing, and moving

• Only for hard work and exercises

• Only when we are awake

• Only for sleeping

How do plants make their own food?

• Through the process of photosynthesis

• By eating other plants

• By absorbing energy from the Sun

• By decomposing dead organisms

What are producers?

• Organisms that can make their own food

• Animals that eat plants

• Organisms that carry out the process of decomposition

• Organisms that eat other living organisms

What is a food chain?

• A model that shows how energy passes from one organism to another in an ecosystem

• A model that shows several interconnected food chains

• The process of decomposition by breaking down dead organisms

• The primary source of energy for all organisms on Earth
