Unit 4 Vocab

Autotroph

• a gas produced by animals during respiration that plants use for photosynthesis

• An organism that obtains its nutrition from simple, inorganic compounds

• Organisms that feed on other organisms in a food chain

Carbon Cycle

• the process of obtaining energy from the breaking of chemical bonds in nutrients

• The process by which one or more substances change to produce one or more different substances

• the continuous movement of carbon among the abiotic environment and living things

Carbon-Oxygen Cycle

• the movement of carbon dioxide and oxygen on Earth by the processes of respiration and photosynthesis.

• the continuous movement of carbon among the abiotic environment and living things

• Show how much energy transfers to the next trophic level in a food chain

Carnivores

• Animals that eat other animals

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

• Animals that eat only plants or plant products

Herbivores

• Animals that eat other animals

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

• Animals that eat only plants or plant products

Decomposers

• Animals that eat other animals

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

• Animals that eat only plants or plant products

Cellular Respiration

• A chemical reaction during which plants convert radiant energy from the Sun to chemical energy; a reaction that converts carbon dioxide and water to sugar (glucose), and oxygen

• The process by which one or more substances change to produce one or more different substances

• the process of obtaining energy from the breaking of chemical bonds in nutrients

Photosynthesis

• A chemical reaction during which plants convert radiant energy from the Sun to chemical energy; a reaction that converts carbon dioxide and water to sugar (glucose), and oxygen

• The process by which one or more substances change to produce one or more different substances

• the process of obtaining energy from the breaking of chemical bonds in nutrients

Chemical Reaction

• The process by which one or more substances change to produce one or more different substances

• the process of obtaining energy from the breaking of chemical bonds in nutrients

Detrital Food Web

• a system consisting of all of the interactions that occur between the abiotic and biotic factors within an environment

• Starts with chemical energy stored in organic debris or waste from other food webs; continues energy flow from debris directly to decomposers that break down the organic matter, which then becomes food and energy for large and larger consumers, and eventually decomposers

• Show how much energy transfers to the next trophic level in a food chain
