Energy from the sun that reaches earth as visible light, & ultraviolet/infrared (heat) radiation.

Energy stored in chemical bonds & released through chemical reactions.

Chemical reaction in which plants convert Sun's radiant energy into chemical energy; converts carbon dioxide & water into glucose & oxygen; photo=light.

Process by which 2 or more chemical substances interact & are chemically changed, producing different chemical substances.

Substance that takes part in & undergoes change during a reaction.

Substance produced during a chemical reaction.

Simple carbohydrates produced by photosynthesis; used to store energy & build structural molecules.

Energy path from 1 organism to another showing a linked series; feeds on the 1 next to it in the series.

Overlapping food chains with different pathways for the flow of food energy in an ecosystem.

Kind of animal that eats both animals & plants; some will hunt & eat their food, others are scavengers & will eat dead matter; "OMNI-" = ALL.

Organisms that transform energy from the Sun & use carbon dioxide & water to make food.

Organisms that feed on other organisms in a food chain.

Animals that only eat plants or plant products; "HERB-" = PLANT.

Animals that eat other animals; "CARN-" = MEAT.

Organisms that get their energy by feeding on producers in the food chain.

Organisms that get their energy by feeding on primary consumers (herbivores) in the food chain.

Organisms that get their energy by eating secondary consumers.

Organisms such as bacteria and fungi that break down the remains of dead plants & animals, without need for internal digestion.

Any class of organisms occupying the same position in a food chain, such as primary consumers or secondary consumers; "TROPH-" = NOURISH.

Shows how much energy transfers to the next trophic level in a food chain.

Smallest particle of an element; made of electrons, protons, & neutrons.

Simplest unit of a chemical compound that can exist, formed when 2 or more atoms join together chemically.

System comprising all the biotic & abiotic factors in an area & all the interactions among them.

Container in the leaves that is the location of photosynthesis & holds chlorophyll.

Green pigment (color) inside the leaves that absorbs sunlight.

Openings in the leaves controlled by guard cells to allow CO2 in and O2 out.

Tubes inside the stem of a plant that carry water from the roots to the leaves.
