Understanding Ecosystems and Plants

What is a primary consumer?

• An animal that eats other animals

• A plant that grows in the soil

• An animal that eats plants as part of its diet

• An organism that breaks down dead materials

What role does a decomposer play in the environment?

• It eats secondary consumers

• It breaks down dead materials into nutrients for the soil

• It consumes plants for energy

• It is eaten by tertiary consumers

Which of these is an example of a tertiary consumer?

• Grass

• Deer

• Lion

• Mushroom

What is a secondary consumer?

• A plant that makes its own food

• An animal that consumes a plant-eating animal

• An organism that breaks down dead matter

• An animal that eats both plants and decomposers

Which of these organisms would be considered a decomposer?

• Eagle

• Rabbit

• Tree

• Mushroom

What is the primary purpose of stomata in plants?

• To absorb water from the soil

• To release and take in gases

• To transport nutrients from the roots

• To help the plant grow taller

Which process allows plants to produce energy using sunlight, water, and carbon dioxide?

• Respiration

• Transpiration

• Photosynthesis

• Digestion

What is the function of xylem in plants?

• To carry sugars to different parts of the plant

• To move water and nutrients from the roots to the leaves

• To allow gases to enter and exit the plant

• To help cool the plant through evaporation

What does the phloem transport in plants?

• Water and nutrients

• Sunlight

• Carbon dioxide

• Sugars produced in the leaves

What is transpiration?

• The process of making food using sunlight

• The movement of water from roots to leaves and its evaporation through the stomata

• The transport of sugars to different plant parts

• The process of absorbing carbon dioxide through stomata
