Energy Flow

There are 4 types of heterotrophs. Match each with its description

•  gets energy from eating vegetation

• herbivore

• gets energy/nutrients from dead matter

• omnivore

• gets energy from eating meat

• detritovore

• gets energy from eating meat and vegetation

• carnivore

Another name for a producer; gets energy from nonliving sources like the sun

Another word for consumer; gets energy from living or once-living sources

Match the following processes with the correct description

• The process some producers use to make food from chemicals.

• photosynthesis

• sunlight, H₂O, and CO₂ are converted into chemical energy stored in glucose.

• cellular respiration

•  glucose is chemically converted into usable chemical energy in the form of ATP

• chemosynthesis

Heterotroph that is critical in returning nutrients back into the soil to be reused by producers.

• herbivore

• omnimvore

• detritovore

• carnivore

The absence of which of the following organisms in a food web would most directly affect other organisms?

• producers

• primary consumers

• secondary consumers

• tertiary consumers

What

happens to the amount of energy in the pyramid as it moves up through the

different levels?

• Energy increases by 10% each level.

• Energy decreases by 90% each level.

• Energy increases by 90% each level.

• Energy decreases by 10% each level.

In a food chain, the flow of energy can flow back and forth between organisms.

• True

• False

Answer explanation

The Flow of energy is ALWAYS one way.

Plants have chloroplasts in their cells filled with chlorophyll, a pigment that ​ (a)   every color of sunlight except for green, and thus ​ (b)   it.

• absorbs
• reflects

Aerobic respiration occurs in the ​ (a)   of oxygen and produces ​ (b)   ATP.

Anaerobic respiration occurs in the ​ (c)   of oxygen and produces ​ (d)   ATP.

• presence
• 36-38
• absence
• 2-4
