Energy Flow

TermDefinition
Producer Definition: Organisms that produce their own food using sunlight (photosynthesis) or chemical reactions (chemosynthesis). Example: Plants, algae, and certain bacteria.
Consumer Definition: Organisms that depend on other organisms for food. Example: Animals, fungi, and some bacteria.
Primary Consumer Definition: Herbivores that feed directly on producers. Example: Grasshoppers, rabbits, cows.
Secondary Consumer Definition: Carnivores or omnivores that feed on primary consumers. Example: Snakes, birds of prey, frogs.
Tertiary Consumer Definition: Apex predators that feed on secondary consumers. They are usually at the top of the food chain. Example: Lions, hawks, or orcas.
Decomposer Definition: Organisms that break down dead or decaying organisms, recycling nutrients back into the ecosystem. Example: Fungi, bacteria, worms.
Scavenger Definition: Animals that feed on dead organisms they did not kill. Example: Vultures, hyenas, crows.
Omnivore Definition: Organisms that eat both plants and animals. Example: Humans, bears, raccoons.
Carnivore Definition: Organisms that primarily eat other animals. Example: Wolves, sharks, tigers.
Herbivore Definition: Organisms that eat only plants. Example: Cows, giraffes, caterpillars.
Food Web Definition: A complex network of interconnected food chains within an ecosystem. Example: In a forest, various food chains (like a rabbit eating grass and a fox eating a rabbit) connect to form a food web.
Energy Pyramid Definition: A graphical representation of the flow of energy through an ecosystem, with producers at the bottom and apex predators at the top. Example: The energy pyramid shows how energy is transferred from one trophic level to the next.
Trophic Level Definition: The position an organism occupies in a food chain or web (e.g., producer, primary consumer, secondary consumer, etc.). Example: A lion is at the fourth trophic level (tertiary consumer) in a grassland ecosystem.
Food Chain Definition: A linear sequence of organisms where each organism serves as food for the next in the chain. Example: Grass → Rabbit → Fox.
Photosynthesis Definition: The process by which plants and other producers use sunlight to synthesize foods from carbon dioxide and water. Example: Plants use sunlight to create glucose, which serves as food for herbivores.
Predator Definition: An animal that hunts and kills other animals for food. Example: A cheetah hunting a gazelle.
Prey Definition: An animal that is hunted and eaten by a predator. Example: A rabbit being hunted by a fox.
Ecology The study of the interactions of organisms with one another and with their environment.
Energy Organisms obtain energy in a variety of ways based upon the way they accumulate energy.
There are three groups: Producers Consumers Decomposers Producers, Consumers, Decomposers
