Ecosystems Quiz

Aiden, Jackson, and Benjamin went on a field trip to a forest. What did they observe there?

• A group of living organisms in a particular space

• The study of animals and nature

• The process of nutrient cycling

• The movement of energy through an ecosystem

Maya, Anika, and Grace are planning a science project on ecosystems. They are discussing the primary source of energy in almost all ecosystems. What do you think they concluded as the primary source?

• Water

• Minerals

• Sunlight

• Soil

Luna, Isla, and Charlotte are studying different organisms in their biology class. They are trying to identify which organisms are capable of photosynthesis. Can you help them?

• Heterotrophs

• Producers

• Consumers

• Decomposers

In a school science project, Aria, James, and Maya are studying an ecosystem. They are observing the role of a lion in the ecosystem. What role does the lion (a heterotroph) play in this ecosystem?

• The lion makes its own food

• The lion breaks down dead organisms and organic wastes

• The lion feeds on producers

• The lion converts sunlight into energy

Avery, Michael, and Jackson went on a field trip to a forest. They observed different organisms at various levels in the food chain. Can you identify the different trophic levels they might have observed in the ecosystem?

• Producer, primary consumer, secondary consumer

• Primary consumer, secondary consumer, tertiary consumer

• Producer, consumer, decomposer

• Autotroph, heterotroph, decomposer

Emma, Harper, and Sophia went on a field trip to a forest. They observed how energy moved from one organism to another. What did they observe?

• The movement of energy through an ecosystem

• The cycling of nutrients within an ecosystem

• The interconnection of food webs

• The flow of energy from the Sun to autotrophs

Rohan, Evelyn, and Avery were discussing their science project on food chains. They were trying to figure out what is the final link in all food chains. Can you help them?

• Producers

• Primary consumers

• Secondary consumers

• Decomposers

Lily, Maya, and Evelyn are studying for their biology exam. They come across a term 'nutrients'. What are nutrients according to their textbook?

• Elements and compounds that organisms obtain from their surroundings

• Energy-rich carbohydrates produced by autotrophs

• The core protoplasm of organisms

• Chemical compounds found in all organisms

Arjun, Priya, and Avery are discussing how organisms obtain nutrients. Which of the following options best describes the process?

• From the atmosphere

• From other organisms

• From sunlight

• From the soil

Ava, Jackson, and Arjun are discussing the difference between the movement of energy and nutrients in an ecosystem. What is the main difference they should focus on?

• Energy flows through the biosphere and cannot be reused, while nutrients are recycled

• Energy is obtained from the Sun, while nutrients are obtained from the soil

• Energy is used by autotrophs, while nutrients are used by heterotrophs

• Energy is transferred through food chains, while nutrients are transferred through biogeochemical cycles
