Energy in Ecosystems

🍄 What do decomposers do in an ecosystem?

• They produce energy through photosynthesis.

• They break down dead matter into nutrients.

• They compete with plants for sunlight.

• They create new organisms from soil.

🌐 What is a food web?

• A single linear chain of energy flow in an ecosystem.

• A network of overlapping food chains showing multiple paths for energy to flow.

• A diagram that only shows producers in an ecosystem.

• A type of food chain that only includes herbivores.

🔁 What is a food chain?

• A linear path of energy transfer: Sun → Plant → Herbivore → Carnivore

• A circular flow of nutrients in an ecosystem

• A complex network of food webs

• A sequence of energy transfer in a food pyramid

🐻 What are omnivores?

• Animals that eat only plants.

• Animals that eat only meat.

• Animals that eat both plants and meat. Example: bears, humans.

• Animals that primarily eat insects.

🦅 What’s the difference between predator and prey?

• Predator = hunted, Prey = hunter

• Predator = scavenger, Prey = herbivore

• Predator = hunter, Prey = hunted

• Predator = omnivore, Prey = carnivore

🌞 What is the main source of energy in a food chain?

• The moon

• The sun

• Artificial lights

• Water

🐍 What are tertiary consumers?

• Organisms that produce their own food through photosynthesis.

• Top-level consumers that eat secondary consumers. Example: snakes, eagles.

• Primary consumers that feed on producers like plants.

• Secondary consumers that primarily eat herbivores.

🌱 What are producers, and how do they get energy?

• Producers are animals that eat plants and get energy from them.

• Producers are plants that use photosynthesis to turn the sun's energy into food.

• Producers are fungi that decompose organic matter for energy.

• Producers are bacteria that convert chemical energy into food.

🐇 What are primary consumers? Give an example.

• Carnivores that eat other animals. Example: lion, tiger.

• Herbivores that eat plants. Example: rabbit, deer.

• Omnivores that eat both plants and animals. Example: bear, human.

• Decomposers that break down dead matter. Example: fungi, bacteria.

⚡ Why does every population need energy?

• To survive, grow, and reproduce—energy fuels life processes.

• To increase the population size rapidly.

• To maintain a stable environment without changes.

• To enhance the aesthetic appeal of the ecosystem.
