Do Now Activity State the difference between a producer and a consumer. What is the similarity between populations and communities? What is the difference between a food web and a food chain?

Section 7-1: ecology Essential Question: How are consumers affected by the process of photosynthesis and cellular respiration? Learning Target Explain how photosynthesis and cellular respiration results in energy flow from producers to top level consumers. Section 7-1: ecology

SUNLIGHT IS THE MAIN SOURCE OF ENERGY FOR LIFE ON EARTH producers SUNLIGHT IS THE MAIN SOURCE OF ENERGY FOR LIFE ON EARTH Some organisms rely on energy stored in inorganic chemical compounds… …Water can be loaded with chemical energy!

ALL ENERGY comes from the sun producers ALL ENERGY comes from the sun

producers Producers “produce” their own food using energy from the sun. ____ are producers. In the blank: plants Example: Plants! They use sunlight, water and CO2 to make energy and oxygen… PHOTOSYNTHESIS Plants

Different types of organisms Autotrophs: organisms that can make their own food (producer)

Different types of organisms Heterotrophs: organisms that eat other organisms (consumer)

Question! If organisms could not do cellular respiration, what would happen to them? They would die from lack of energy (ATP) If plants couldn’t do photosynthesis, what would happen to consumers? The food chain would collapse…everything would die.

Different types of consumers Herbivores: eat only plants (primary)

Different types of consumers Carnivores: eat only animals (secondary/tertiary/quarternary)

Different types of consumers Omnivores: eat plants and animals (secondary/tertiary/quarternary)

Different types of consumers Detrivores: eat dead plants and animals

Different types of consumers Decomposers: breaks down dead plants and animals
