Energy Flow through an Ecosystem Photosynthesis Food Chains

Energy Flow through an Ecosystem Photosynthesis, Food Chains, Food Webs, & Energy Pyramids 1

Organisms that can make glucose during photosynthesis 2

Plants use ______ they receive from the sun & convert it to _______ in a process called ______. 3

6 CO 2 + 6 H 2 O + sunlight & chlorophyll C 6 H 12 O 6 + 6 O 2 4

Producers use of the energy make for most they ______. 5

The energy that is not used by producers can be passed on to organisms that cannot make their own energy. 6

Organisms that cannot make their own energy 7

A consumer that eats producers to get energy: • Is called a (primary) or __________ 8

Most of the energy the primary consumer gets from the producer is used by the consumer. Some energy is stored and can be passed on. 9

A consumer that eats another consumer for energy: • Is called a _____ or second order consumer 10

Most of the energy the secondary consumer gets from the primary consumer is used by the secondary consumer. Some energy is stored and can be passed on. 11

A consumer that eats a consumer that already ate a consumer: • Is called a 3 rd order or _____ consumer 12

Types of Consumers: Organism that cannot make its own food so it consumes plants and animals. Organism that cannot make its own food so it consumes other animals. Organism that breaks down dead plants and animals to recycle nutrients in the environment. Think of examples for each type of consumer! 13

Consumers that eat other dead consumers are called ____ 14

The transfer of energy from the sun to producer to primary consumer then to higher order consumers 15

Another way of showing the transfer of energy in an ecosystem 18

Food Chains Show Available Energy 19

Energy Pyramids Show • It takes a large number of producers to support a small number of primary consumers • It takes a large number of primary consumers to support a small number of secondary consumers • Energy is transferred up the food pyramid 20

21

• Interconnected food chains • They show the feeding relationships in an ecosystem 22

What do the arrows represent? Energy transfer from organism to organism in the food web 23

How are food webs limited models? Food webs do not include all parts (animals and resources) of an ecosystem. 24

How Many Chains are in this web? 25
