Ecosystem Dynamics And Survival Quiz

1. What are the roles of producers, consumers, and decomposers in an ecosystem?

Decomposers create food for the consumers by breaking down the sun's energy.

Producers eat the consumers and turn them into energy.

Consumers take the sun's energy and turn it into food for producers.

In an ecosystem, producers are the organisms that can make their own food using sunlight, consumers are organisms that consume other organisms for energy, and decomposers break down dead organisms and waste to recycle nutrients back into the ecosystem.

Explanation

In an ecosystem, producers are the organisms that can make their own food using sunlight, consumers are organisms that consume other organisms for energy, and decomposers break down dead organisms and waste to recycle nutrients back into the ecosystem.

2. How can an ecosystem be best described?

A group of animals living in the same geographical area.

The process of photosynthesis in plants.

A community of organisms interacting with biotic and abiotic features

A collection of rocks and minerals.

An ecosystem involves all living organisms and their interactions with both living and non-living components of their environment, making the correct answer the most comprehensive and accurate description.

Explanation

An ecosystem involves all living organisms and their interactions with both living and non-living components of their environment, making the correct answer the most comprehensive and accurate description.

3. What do organisms need to survive?

Warmth, space, and nutrients

Love, happiness, and success

Light, air, and water

Money, power, and fame

Organisms require warmth to maintain body temperature, space to grow and move freely, and nutrients to fuel their bodies. None of the incorrect answers are essential for the basic survival of organisms.

Explanation

Organisms require warmth to maintain body temperature, space to grow and move freely, and nutrients to fuel their bodies. None of the incorrect answers are essential for the basic survival of organisms.

4. The food web has _____ paths of energy, the food chain has ______ path of energy.

Several, a few

Multiple, single

Many, one

Allone

In a food web, multiple paths of energy flow between different organisms, while in a food chain, there is a single linear path of energy transfer from one organism to another.

Explanation

In a food web, multiple paths of energy flow between different organisms, while in a food chain, there is a single linear path of energy transfer from one organism to another.
