Example Question #63 : 5th Grade Science

How are organisms dependent on one another in the food chain? (A graphic of a food chain is provided below.)

Screen shot 2020 06 29 at 12.33.33 pm

Possible Answers:

Organisms depend on one another for completing tasks.

Organisms rely on one another for company.

Organisms are not dependent on one another.

Organisms depend on one another for energy.

Correct answer:

Organisms depend on one another for energy.

Explanation:

Organisms are dependent on each other for a source of energy. Producers rely on the Sun, consumers rely on producers and smaller prey earlier in the chain, and final consumers need weaker animals to feed on. Each organism has a role to play, and the others will not survive if one link in the chain goes missing.

Example Question #64 : 5th Grade Science

How do living things adapt when there are changes in the food chain? (A graphic of a food chain is provided below.)

Possible Answers:

They may need to move locations.

All of the answer choices are correct.

They may need to find new sources of energy.

They may have to change their habits to conserve energy.

Correct answer:

All of the answer choices are correct.

Explanation:

The Department of Education and Training for Victoria State in Canada explains in scientific terms how energy is transferred through the food chain when all the necessary organisms are present, "Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants. The majority of the chemical energy stored in plants is transformed into other forms by an assortment of consumers, such as cows, rabbits, horses, sheep, caterpillars, and other insects eating plants. Some of the stored chemical energy in a producer such as grass is stored as chemical energy in the fat or protein in the first-order consumers that eat the grass. This energy is available for higher-order consumers. At each stage of a food chain, most of the chemical energy is converted to other forms such as heat and does not remain within the ecosystem." If organisms are missing from the food chain, animals can adapt by finding another source of energy, conserving energy, moving locations, or they will not survive.

Example Question #65 : 5th Grade Science

Animals that hunt other animals to eat are _______________.

Possible Answers:

herbivores

decomposers

carnivores

producers

Correct answer:

carnivores

Explanation:

Animals that hunt and eat other animals are called carnivores. This means they eat only meat. Animals like hawks, sharks, lions, and owls are examples of carnivores. They have specially adapted features to allow them to excel at hunting and eating meat. Strong talons, sharp beaks, sharp teeth, powerful jaw, and night vision are just a few adaptations. They still receive energy from the Sun and producers as they consume other animals in the food chain, but they do not directly eat the producers.

Example Question #66 : 5th Grade Science

Which organism would most likely come after the snake in the food chain?

Screen shot 2020 06 29 at 2.49.48 pm

Possible Answers:

Golden Eagle, Eagle, Golden, Nature

Kitty, Cat, Kitten, Pet, Animal, Cute

Grasshopper, Insect, Red, Animal, Fauna

Spider, Tarantula, Creepy, Scary

Correct answer:

Golden Eagle, Eagle, Golden, Nature

Explanation:

This food chain shows a producer (grass), then a mouse, which is an herbivore, and a snake, which is a consumer. Whichever consumer comes after, the snake must be a predator to the snake. The Golden Eagle is a predator to the snake and could eat it. Energy is passed along the food chain from each organism to the next.

Example Question #67 : 5th Grade Science

On the diagram below, which would be a secondary consumer?

Screen shot 2020 06 29 at 3.07.02 pm

Possible Answers:

Mouse

Snake

Bird

Grass

Correct answer:

Snake

Explanation:

Each organism in the food chain plays a specific role and has a title. The grass is a producer and creates its food, using sunlight, water, and carbon dioxide. A mouse in this food chain would be the primary consumer. A secondary consumer eats the primary consumer, so it would be the snake. The hawk is the final consumer and the top predator in the food chain. The mushrooms represent the decomposer that breaks down waste from animal and plant remains.

Example Question #68 : 5th Grade Science

Which of the following is an example of something that is abiotic?

Possible Answers:

a mouse

a flower

mushrooms

a rock

Correct answer:

a rock

Explanation:

The term abiotic means something that is not living; it is devoid of life. Abiotic materials are still part of an ecosystem, but they are not living organisms. Of the answer choices, only one is a nonliving thing, a rock. The other options are all living organisms and are biological rather than physical.

Example Question #69 : 5th Grade Science

Which of the following choices represents two consumers?

Possible Answers:

An acorn and grasshopper

A turtle and an oak tree

A cat and a rabbit

A mushroom and a fish

Correct answer:

A cat and a rabbit

Explanation:

Organisms are dependent on each other for a source of energy. Producers rely on the Sun, consumers rely on producers and smaller prey earlier in the chain, and final consumers need weaker animals to feed on. Each organism has a role to play, and the others will not survive if one link in the chain goes missing. In the answer choices, both of the organisms must be living and consume or eat other organisms for energy. A rabbit eats producers like grass and fruit while a cat eats meat from birds, lizards, and mice. Both of these organisms are consumers.

Example Question #70 : 5th Grade Science

Which of the following groups are examples of carnivores?

Possible Answers:

lions, giraffes, frogs

humans, lions, hyenas

wolves, tigers, cheetahs

spiders, cows, raccoons

Correct answer:

wolves, tigers, cheetahs

Explanation:

Animals that hunt and eat other animals are called carnivores. This means they eat only meat. Animals like wolves, tigers, and cheetahs are examples of carnivores. They have specially adapted features to allow them to excel at hunting and eating meat. Strong talons, sharp beaks, sharp teeth, powerful jaw, and night vision are just a few adaptations. They still receive energy from the Sun and producers as they consume other animals in the food chain, but they do not directly eat the producers.

Example Question #31 : Movement Of Matter

Consumers, producers, and decomposers are all

Possible Answers:

abiotic

herbivores

biotic

carnivores

omnivores

Correct answer:

biotic

Explanation:

All consumers, producers, and decomposers are biotic. This means that they are all living, biological organisms. Biotic factors in an ecosystem or food chain can describe either the consumer or the producer. Decomposers are also living things and fall into the category of biotic.

Example Question #32 : Movement Of Matter

Which answer choice below describes an omnivore and gives an accurate example of one?

Possible Answers:

An omnivore is an organism that eats both plant and animal products. An example is humans.

An omnivore is an organism that only eats plants and plant by-products. An example is a rabbit.

None of the answer choices are correct.

An omnivore is an organism that only eats animal products. An example is a cheetah.

Correct answer:

An omnivore is an organism that eats both plant and animal products. An example is humans.

Explanation:

Omnivores are organisms that eat both plant and animal products. Humans are an example of an omnivore because we eat meat like beef, pork, fish, and chicken and eat fruits and vegetables, which are plants or plant by-products. A carnivore only eats animal products (like a cheetah), and herbivores only eat plants and plant by-products (like a rabbit).
