True/False Questions
100

This process occurs in plants and uses sunlight to make food.

What is photosynthesis?

100

This type of organism is at the base of most food webs and produces its own food using sunlight.

What is a producer?

100

This step of the water cycle involves water from oceans, lakes, and rivers turning into water vapor.

What is evaporation?

100

Phytoplankton are responsible for producing about this percentage of the oxygen in Earth's atmosphere.

50%

100

True or False: Consumers produce their own food

False

200

This process releases energy from food by breaking down glucose.

What is cellular respiration 

200

This term describes an organism that breaks down dead material to obtain energy.

What is a detritivore?

200

This step of the water cycle occurs when water vapor cools and forms clouds.

What is condensation ?

200

This process releases carbon into the air and soil as organic material breaks down.

  • Decomposition
200

True or False: Energy cycles through ecosystems because it returns to the Sun.

False

300

This is the main product of photosynthesis that provides energy for organisms.

What is glucose?

300

These organisms are at the top of the food chain and typically consume other animals.

What is a carnivore 

300

This is what happens when clouds become too heavy, and water falls back to Earth.

What is precipitation?

300

This is a fossil fuel where carbon is stored in the form of ancient plants and animals.

 coal (or oil or natural gas)

300

True or False: In a food web, energy flows from the producers to the consumers.

True

400

These two processes are opposites, with one producing oxygen and glucose, and the other using them to release energy.

What are photosynthesis and cellular respiration ?

400

his organism eats both plants and animals, making it a(n) __________.

Omnivore

400

This is the process by which plants release water vapor into the atmosphere.

What is transpiration

400

This is the main way energy flows through ecosystems, beginning with sunlight.

Photosynthesis 

400

True or False: Cellular respiration is the process by which plants use sunlight to make their own food.

False-Cellular respiration is the process by which cells break down glucose to release energy. Photosynthesis is the process by which plants make food using sunlight.) 

500

This part of the cell is where cellular respiration occurs to release energy from glucose.

Mitochondria 

500

This term describes a group of food chains that are interconnected in an ecosystem.


Answer: What is a food web?

500

This happens when water moves from the Earth's surface, through the atmosphere, and back to the surface again, continuing in a cycle.

What is the water cycle ?

500

This element is a key part of glucose, carbon dioxide, and other organic compounds, and is cycled through ecosystems.

What is carbon ?

500

True or False: Energy is recycled in ecosystems.

False (Energy flows through ecosystems in one direction, it does not get recycled. However, nutrients are recycled.)
