DOK Level 1: Recall

Which process do autotrophs primarily use to convert sunlight into chemical energy?

• Respiration

• Photosynthesis

• Fermentation

• Chemosynthesis

Tags

DOK Level 1: Recall

Identify the role of producers in an ecosystem.

• Decompose dead organisms

• Consume other living organisms

• Create energy-rich compounds (like glucose) from sunlight

• Store energy in the form of lipid molecules

Tags

DOK Level 1: Recall

Which of the following best describes a heterotroph?

• An organism that produces its own food

• An organism that consumes other organisms for energy

• An organism that uses sunlight to produce energy

• An organism that uses chemical reactions to produce energy

DOK Level 1: Recall

Explain the role of chlorophyll in the photosynthesis process.

• It absorbs water for the plant

• It captures light energy from the sun

• It transports nutrients within the plant

• It releases oxygen into the atmosphere

Tags

DOK Level 2: Skill/Concept

How do autotrophs differ from heterotrophs in terms of energy acquisition?

• Autotrophs rely on consuming other organisms, while heterotrophs produce their own food

• Autotrophs produce their own food, while heterotrophs rely on consuming other organisms

• Both rely on consuming other organisms

• Both produce their own food

DOK Level 2: Skill/Concept

Describe the process of chemosynthesis and its significance in ecosystems.

• It is the process of converting sunlight into energy, significant in desert ecosystems

• It is the process of converting chemical energy into organic compounds, significant in deep-sea ecosystems

• It is the process of breaking down organic matter, significant in forest ecosystems

• It is the process of converting water into oxygen, significant in aquatic ecosystems

DOK Level 2: Skill/Concept

What is the main difference between photosynthesis and chemosynthesis?

• Photosynthesis uses sunlight, while chemosynthesis uses chemical reactions

• Photosynthesis occurs in animals, while chemosynthesis occurs in plants

• Photosynthesis produces carbon dioxide, while chemosynthesis produces oxygen

• Photosynthesis occurs in the dark, while chemosynthesis requires light

Tags

DOK Level 2: Skill/Concept

Evaluate the importance of producers in food chains.

• They are the primary source of energy for all other organisms

• They decompose dead organisms

• They are the top predators in the ecosystem

• They provide shelter for other organisms

DOK Level 3: Strategic Thinking

Analyze how the absence of chlorophyll would affect a plant's ability to perform photosynthesis.

• The plant would produce more oxygen

• The plant would be unable to capture light energy

• The plant would grow faster

• The plant would produce more glucose
