Explanation:

Step1: Fill in introduction section

Organisms need energy to survive. All energy originates from the sun and is transferred from organism to organism through a food chain/web. The position an organism occupies in a food chain is known as a trophic level. The flow of energy is represented using arrows. The arrows should always point from the prey/food source to the organism that eats/consumes it.
Example food chain doodle: Sun → Grass → Rabbit → Owl (with simple drawings of each organism)

Step2: Fill in Producers section

Producers are found in the 1st (first) trophic level. They make food/energy by converting the sun's light energy into glucose (sugar) in a process known as photosynthesis. Plants are the primary producers of most ecosystems.
Doodle example: A simple drawing of grass or a tree

Step3: Fill in Primary Consumers section

Primary consumers make up the 2nd (second) trophic level. They are organisms that eat producers/plants, also known as herbivores (plant eaters).
Doodle example: A simple drawing of a rabbit or caterpillar

Step4: Fill in Secondary Consumers section

Secondary consumers make up the 3rd (third) trophic level. They are organisms that eat primary consumers/herbivores. Secondary consumers can be carnivores (meat-eaters) or omnivores (eat plants/animals).
Doodle example: A simple drawing of a snake or fox

Step5: Fill in Tertiary Consumers section

Tertiary consumers make up the 4th (fourth) trophic level. They are organisms that eat secondary consumers. Tertiary consumers are usually carnivorous top predators, but they can also be omnivores.
Doodle example: A simple drawing of an owl or eagle

Step6: Fill in 10% Rule section

What is the 10% Rule?
As energy moves from one trophic level to the next, only about 10% of the energy is passed on to the higher level; the remaining 90% is lost as heat or used for the organism's life processes.

Answer:

Introduction Completed:

Organisms need energy to survive. All energy originates from the sun and is transferred from organism to organism through a food chain. The position an organism occupies in a food chain is known as a trophic level. The flow of energy is represented using arrows. The arrows should always point from the food source to the organism that consumes it.
Example food chain: Sun → Grass → Rabbit → Owl (with corresponding doodles)

Trophic Levels Completed:

1. Producers: 1st trophic level. They make food by converting solar energy into glucose via photosynthesis. Plants are the primary producers of most ecosystems. (Doodle: grass)
2. Primary Consumers: 2nd trophic level. They eat producers, also known as herbivores. (Doodle: rabbit)
3. Secondary Consumers: 3rd trophic level. They eat primary consumers. They can be carnivores or omnivores. (Doodle: snake)
4. Tertiary Consumers: 4th trophic level. They eat secondary consumers. They are usually top predators, but can also be omnivores. (Doodle: owl)

10% Rule Completed:

As energy moves from one trophic level to another, only ~10% of energy is transferred to the next level; the rest is lost as heat or used for the organism's metabolism.
