Question

take notes on each trophic level as you follow the flow of energy from the sun to the top predator. include at least one doodle for each trophic level.

tertiary consumer
tertiary consumers make up the ____ trophic level. they are organisms that eat ____________________. tertiary consumers are usually carnivorous __________, but they can also be ____________

secondary consumers
secondary consumers make up the ____ trophic level. they are organisms that eat ____________________. secondary consumers can be __________ (meat-eaters) or ____________ (eat plants/animals).

primary consumers
primary consumers make up the ____ trophic level. they are organisms that eat ____________________, also known as ____________ (plant eaters).

producers
producers are found in the ____ trophic level. they make __ by converting the __ energy into __________ (sugar) in a process known as ____________________. plants are the primary ____________ of most ecosystems.

all energy originates from the sun.
the sun

what is the 10% rule?
as energy moves from one ____ to the next, only __ of the energy is passed on. the other __ is lost as ____.

Explanation:

Fills in each trophic level and 10% rule based on ecological energy flow concepts.

1. Producers: Base trophic level (1st) that makes food via photosynthesis using sunlight.
2. Primary Consumers: 2nd trophic level, eat producers (herbivores).
3. Secondary Consumers: 3rd trophic level, eat primary consumers; can be carnivores or omnivores.
4. Tertiary Consumers: 4th trophic level, eat secondary consumers; usually carnivores, sometimes omnivores.
5. 10% Rule: Only 10% of energy transfers between trophic levels; 90% lost as heat.

Answer:

TERTIARY CONSUMER

Tertiary consumers make up the 4th trophic level. They are organisms that eat secondary consumers. Tertiary consumers are usually carnivorous top predators, but they can also be omnivores.

SECONDARY CONSUMERS

Secondary consumers make up the 3rd trophic level. They are organisms that eat primary consumers. Secondary consumers can be carnivores (meat-eaters) or omnivores (eat plants/animals).

PRIMARY CONSUMERS

Primary consumers make up the 2nd trophic level. They are organisms that eat producers/plants, also known as herbivores (plant eaters).

PRODUCERS

Producers are found in the 1st trophic level. They make glucose by converting the sun's energy into chemical energy (sugar) in a process known as photosynthesis. Plants are the primary producers of most ecosystems.

WHAT IS THE 10% RULE?

As energy moves from one trophic level to the next, only 10% of the energy is passed on. The other 90% is lost as heat.

(Suggested doodles: Sun for the energy source; a plant for producers; a rabbit for primary consumers; a fox for secondary consumers; an eagle for tertiary consumers)
