What are the differences between autotrophs and heterotrophs?

• Autotrophs consume other organisms for food, while heterotrophs produce their own food.
• Autotrophs and heterotrophs both produce their own food.
• Autotrophs and heterotrophs both consume other organisms for food.
• Autotrophs produce their own food, while heterotrophs consume other organisms for food.

What is chemosynthesis?

• The process by which organisms use sunlight as an energy source to produce food.
• The process by which organisms use water as an energy source to produce food.
• The process by which organisms use oxygen as an energy source to produce food.
• The process of breaking down and using the energy in chemical compounds to make food.

What are consumers?

• Organisms that depend on other organisms for food and energy.

• Government agencies that regulate consumer protection
• Businesses that sell goods and services
• Individuals or households that produce goods and services for personal use

Define heterotrophs.

• Organisms that obtain energy by consuming other organisms or organic matter.
• Organisms that obtain energy by photosynthesis.
• Organisms that obtain energy from inorganic matter.
• Organisms that obtain energy from the sun.

Describe food chains.

• Food chains describe the hierarchy of organisms in an ecosystem.
• Food chains describe the process of photosynthesis in plants.
• Food chains describe the interaction between predators and prey in an ecosystem.
• Food chains are diagrams that show the flow of energy and matter from one organism to another in an ecosystem.

What are producers?

• Organisms that rely on other organisms for food.
• Organisms that consume other organisms for food.
• Organisms that use light or chemical energy to make food for themselves and other organisms.

• Organisms that cannot make their own food.

What is photosynthesis?

• The process by which green plants and some other organisms use moonlight to synthesize foods with the help of chlorophyll in their cells.
• The process by which green plants and some other organisms use sunlight to break down foods with the help of chlorophyll in their cells.
• The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll in their cells.
• The process by which green plants and some other organisms use sunlight to synthesize water with the help of chlorophyll in their cells.

What are autotrophs?

• Autotrophs are organisms that rely on other organisms for food.
• Autotrophs are organisms that can only produce food using energy from organic substances.
• Autotrophs are organisms that cannot produce their own food.
• Autotrophs are organisms that use energy directly from the sun or form chemical bonds.

Define food.

• Organic molecules, such as glucose, that organisms use for chemical energy.

• Organic molecules consumed for medicinal purposes.

• Any substance consumed for hydration.
• Any substance consumed for pleasure.

Compare photosynthesis and cellular respiration.

• Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into energy, carbon dioxide, and water.
• Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen, while cellular respiration is the process by which cells break down glucose and oxygen to produce energy, carbon dioxide, and water.
• Cellular respiration is the process by which cells convert sunlight, water, and carbon dioxide into glucose and oxygen.
• Photosynthesis is the process by which cells break down glucose and oxygen to produce energy, carbon dioxide, and water.
