Q3 Test Review

How do organisms get the energy they need?

• plants get energy from fertilizers, and animals get energy by drinking water

• Plants get energy from glucose produces in the soil, and animals get energy directly from sunlight.

• plants do not require energy because they do not move, and animals get energy by performing exercise.

• plants break down and use the glucose they produced in photosynthesis, and animals get energy from eating other organsism.

What part of a plant transports water and nutrients from the rot to the plant's stem and leaves?

• root hairs

• phloem

• xylem

• cuticle

When plants make glucose, they are converting the sun's radiant energy into-

• ATP

• chemical energy that can be stored

• in a process known as cellular respiration

• into chlorophyll

Why is photosynthesis important to consumers?

• Consumers use oxygen and glucose produced by photosynthesis

• consumers supply the light energy needed for photosynthesis

• consumers supply the water needed for photosynthesis

• consumers supply the chloroplasts to producers

Logan eat a banana for breakfast every morning. Which of the following describes the chain of energy transfers that occurred?

• Energy is transferred from the Sun, to the banana tree, to Logan

• Energy is transferred from Logan, to the banana, to the banana tree, to the sun

• Energy is transferred from the sun, to Logan, to the banana, to the banana tree

• Energy is transferred from the banana tree, to the banana, to the sun, to Logan

Fox squirrels are common in Texas. Fox squirrels primarily eat acorns and nuts from tress but also eat insects. Some predators of fox squirrels include owls, snakes, and bobcats.

Which diagram best represents how energy would flow to and from the fox squirrel?

• 
• 
• 
• 

Andrew built a biotic community by adding aquatic plants, snails, and small fish into a large jug and placed the jug outside. He noticed 3 days later that all of the snails had been eaten by the fish.

Which best represents the energy flow in this biotic community?

• sun -> plants -> snails -> fish

• sun<-plants<- snails<- fish

• fish-> snails-> plants-> sun

• sun<-snails<-plants<-fish

Which of the following energy transformation occur when humans use energy from food to exercise?

• mechanical->thermal-> chemical

• thermal->electrical->mechanical

• radiant->mechanical->thermal

• chemical->mechanical->thermal

What kind of energy is stored in food?

• thermal

• chemical

• mechanical

• electrical

Plants get their energy from the sun through photosynthesis. This energy is trapped in the bonds of the complex compounds the plants create from carbon dioxide and water. The plants are then eaten by animals, and the energy is used for heat and movement.

Which of the following is an energy transfer that is conducted inside an animal in the above scenario?

• radiant energy to mechanical energy

• radiant energy to chemical energy

• chemical energy to mechanical energy

• chemical energy to radiant energy
