| Question | Answer |
|---|---|
| ecosystem | all the living and nonliving things in an environment and how they interact; it can be as large as an ocean or as small as a drop of water |
| habitat | a place where an animal lives |
| chlorophyll | the green substance found in plants that traps energy from the sun and gives plants their green color |
| carbon dioxide | a gas found in the air that is expelled (breathed out) by humans |
| photosynthesis | a process by which plants change light energy from the sun and use it to make sugar (sun + water + CO2= glucose and O2) |
| producer | a living thing that uses sunlight to produce sugar; plants are producers |
| consumer | a living thing that gets energy by eating (consuming) plants and other animals |
| herbivore | a consumer that only eats plants (deer, cows, rabbits...) |
| carnivore | a consumer that only eats other consumers (lions, wolves, eagles...) |
| omnivore | a consumer that eats both plants and other consumers (bears, raccoons, lemurs, humans ...) |
| scavenger | an animal that eats dead animals (vultures, hyenas...) |
| decomposer | a consumer that breaks down dead plants and animals and puts materials back into the soil, air, and water (earthworms, bacteria...) |
| food chain | the flow of energy through a community |
| food web | all the food chains in a community |
| predator | an animal that hunts and kills other animals for food; the hunter |
| prey | the animals that are hunted by predators; the hunted |
| non-living things | things that do NOT grow and reproduce such as sunlight, rocks, soil, air, and water |
| living organisms | carry out basic life functions such as: grow and develop, get rid of waste, reproduce, and get energy from food |
| algae | similar to a plant that grows in water; they make their own food through photosynthesis but do not have leaves, stems, or roots |
| bacteria | microorganisms that act as decomposer |
| phytoplankton | Microscopic, free floating, organisms that function as producers in marine ecosystems; they produce more than half of the world's oxygen |
| zooplankton | microscopic animals (think zoo) that swim or drift near the surface of marine ecosystems |
| invasive species | species that enter a new ecosystem and multiply, harming native species and their habitats (Burmese python in Florida, latternfly in NY...) |
