Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What term describes an animal that eats only plants in an energy model?

Answer: Herbivore. Herbivores are primary consumers that get energy directly from plants.

Flashcard 2: Which direction does energy move in a food chain: from prey to predator or predator to prey?

Answer: From prey to predator. Energy flows from the organism being eaten to the one eating it.

Flashcard 3: What is a producer in an energy-transfer model of a food chain?

Answer: An organism that makes its own food, usually a plant. Producers convert light energy into chemical energy through photosynthesis.

Flashcard 4: What form of energy do plants store in the food they make?

Answer: Chemical energy. Glucose and other organic molecules store energy from photosynthesis.

Answer: Energy being transferred from one organism to another. Arrows show the direction of energy flow through consumption.

Flashcard 19: Which level has the most available energy in an energy pyramid model?

Answer: Producers (plants). Energy decreases at each level, so the base has the most.

Flashcard 20: What is the term for an organism that must get energy by eating other organisms?

Answer: Consumer. Consumers cannot make their own food and depend on other organisms for energy.

Flashcard 21: What is the original source of most energy in a food chain that starts with plants?

Answer: The Sun. Plants capture solar energy through photosynthesis to start food chains.

Flashcard 22: In the chain seeds → mouse → snake, which organism has energy that originally came from the Sun?

Answer: All of them (seeds, mouse, and snake). All energy in food chains originates from the Sun.

Flashcard 23: Which direction should arrows point in an energy transfer model: toward the eater or toward the eaten?

Answer: Toward the eater (the organism receiving energy). Arrows show energy flow direction from food source to consumer.

Flashcard 24: Which model correctly shows energy transfer: Sun → plant → rabbit or rabbit → plant → Sun?

Answer: Sun → plant → rabbit. Energy flows from Sun to producers to consumers.

Flashcard 25: What is photosynthesis in an energy-transfer model from Sun to plants?

Answer: Plants use sunlight to make sugar (stored chemical energy). Light energy converts to chemical energy stored in glucose molecules.

Flashcard 26: What is the term for the first consumer in a food chain that eats producers?

Answer: Primary consumer. First-level consumers feed directly on producers in the food chain.

Flashcard 27: Which arrow direction correctly shows energy transfer: plant → rabbit or rabbit → plant?

Answer: plant → rabbit. Arrows point toward the organism receiving energy through consumption.

Flashcard 28: What is the term for an organism, such as a plant, that makes its own food using sunlight?

Answer: Producer. Producers convert light energy into chemical energy through photosynthesis.

Flashcard 29: What is a food web model?

Answer: A model of many connected food chains in an ecosystem. Shows complex feeding relationships and energy pathways.

Flashcard 30: Find the organism that returns nutrients by decomposition in this model: tree → deer → wolf → fungi.

Answer: Fungi. Fungi break down dead organisms, recycling nutrients to the ecosystem.

Flashcard 31: Identify the primary consumer in this chain: grass → rabbit → hawk.

Answer: Rabbit. Rabbit eats the grass, making it the first consumer.

Flashcard 32: What is a producer in an energy transfer model involving plants and animals?

Answer: An organism that makes its own food, usually a plant. Producers convert light energy into chemical energy through photosynthesis.

Flashcard 33: What do decomposers do in an ecosystem energy model after plants and animals die?

Answer: They break down dead matter and recycle nutrients. Decomposers return nutrients to soil for plants to use.

Flashcard 34: What is the stored form of energy in food molecules that moves through a food chain?

Answer: Chemical energy. Energy is stored in molecular bonds and transferred when organisms eat.
