1. Animals who cannot make their own food are ________ in the food chain.
- Answer: Consumers
- Explanation: Animals that cannot produce their own food (e.g., through photosynthesis) rely on other organisms for energy and are therefore called "consumers."

2. Cows are typically ________, meaning they only eat plants.
- Answer: Herbivores
- Explanation: Herbivores are animals that exclusively eat plants.

3. The series of plants and animals in which each organism is a source of food for the next is known as a ________.
- Answer: Food chain
- Explanation: A food chain represents the linear transfer of energy from one organism to another in an ecosystem.

4. Animals that are ________ are hunted by other animals as food.
- Answer: Prey
- Explanation: Prey refers to organisms that are hunted and eaten by predators.

5. ________ speed up the decaying process and release nutrients back into the food chain.
- Answer: Decomposers
- Explanation: Decomposers, such as bacteria and fungi, break down dead organic matter and recycle nutrients back into the ecosystem.

6. Plants are called ________ because they are able to use light energy from the sun to produce food from carbon dioxide in the air and water.
- Answer: Producers
- Explanation: Plants are producers because they can create their own food through photosynthesis, serving as the primary source of energy in most ecosystems.

7. If an animal eats only meat, it is known as a ________.
- Answer: Carnivores
- Explanation: Carnivores are animals that feed exclusively on other animals.

8. Animals that kill and hunt other animals for food are known as ________.
- Answer: Predators
- Explanation: Predators are animals that actively hunt and consume prey.

9. ________ ecosystems are areas such as grasslands, forests, and savannas.
- Answer: Terrestrial
- Explanation: Terrestrial ecosystems are land-based ecosystems, including grasslands, forests, and savannas.

10. Oceans, ponds, and rivers are ________ types of ecosystems.
- Answer: Aquatic
- Explanation: Aquatic ecosystems are water-based ecosystems, including oceans, ponds, and rivers.

11. Plants and animals that are consumed by multiple organisms are called ________.
- Answer: Prey
- Explanation: Prey organisms are those that are eaten by other organisms in the food chain.

12. Human beings are known as ________ because they eat both meat and plants.
- Answer: Omnivores
- Explanation: Omnivores are organisms that consume both plants and animals.

#### Part Two: Give an example of a food chain. Include at least 4 links on the food chain. If you do an illustration, make sure it is labeled.

Example Food Chain:
1. Grass (Producer) →
2. Rabbit (Herbivore/Primary Consumer) →
3. Snake (Carnivore/Secondary Consumer) →
4. Hawk (Carnivore/Tertiary Consumer)

Explanation:
- Grass produces its own food through photosynthesis and serves as the base of the food chain.
- The rabbit eats the grass, obtaining energy as a primary consumer.
- The snake preys on the rabbit, becoming a secondary consumer.
- The hawk preys on the snake, acting as a tertiary consumer at the top of this simplified food chain.
