Focus

​

Lots of Names.....

Producer, Consumer, Secondary Consumer, Tertiary Consumer, Autotroph, Heterotroph

Match

Match the following - some answers fit for others but all answers should work like a puzzle, use the internet if you need help.

• Producer

• Plant

• Autotroph

• Consumer

• Heterotroph

Plant

Autotroph

Makes its own energy

Eats other Organisms

Consumer

• Plant

• Autotroph

• Makes its own energy

• Eats other Organisms

• Consumer

​The Skinny

​Autotroph - Creates it's own energy from the environment around it.

• ​Plants

• Producers

Plants, Producers, and Autotrophs are all interchangeable words.

Some text here about the topic of discussion

​Heterotroph - Eats other organisms to get energy

• Animals

• Consumer (primary, secondary, tertiary)

​Heterotroph, Consumer and Animal are all interchangeable.

​Energy Pyramid

​Energy Transfer

​10% of energy transfers at each level, 90% is lost. Energy begins at the the sun, then to our producers and transfers to our consumers. This is the basic concept that fuels a food web or food chain

Multiple Choice

What is this?

• Food Web

• Trophic Pyramid

• Food Chain

• Trophic Web

Multiple Choice

What is this?

• Food web

• Food chain

• Trophic Chain

• Trophic Pyramid

Multiple Choice

Energy Transfer supports the concepts of the Law of Conservation of Energy which states.

• Energy is created at the sun and then passed on to other organisms

• Energy cannot be created but it can be used up

• Energy cannot be created or destroyed it can only change forms

• Plants create the energy that we all use.
