6-2 Energy & Matter Part I (Food Chains, etc)
Terms in this set (20)
Organisms that use an outside energy source to make their own food (glucose) through the process of photosynthesis (using the sun) or chemosynthesis (using chemical energy).
Organisms that cannot make their own food.
Organisms that consume the dead bodies and wastes that are produced by living things
Organisms that eat producers.
Organisms that eat herbivores, omnivores, and even other carnivores.
Organisms that eat both producers and consumers.
Detritivores that eat the bodies of of animals killed by carnivores or omnivores.
A simple model (beginning with a producer) that shows one path of food energy in a community or ecosystem.
A model for energy transfer that shows how many different food chains are interconnected.
A model that shows how much energy is available at each link of a food chain (or trophic level in an ecosystem).
The approximate amount of energy that moves up to the next level in a community or ecosystem
The approximate amount of energy that is lost (due to metabolism, heat, waste) from one level to the next in an energy pyramid.
The feeding levels in a community or ecosystem. The first level includes producers, the second level includes herbivores, and the 3rd level includes the carnivores, omnivores, etc.
A type of sugar that is used for energy in living things
The chemical process that uses carbon dioxide, water, and light to produce glucose and oxygen.
The chemical process that uses hydrogen sulfide or methane instead of light to produce glucose (oxygen is not released as a by product).
Cracks in the Earth's surface in the deep ocean that release chemicals that support chemosynthesis.
An animal that eats a producer- an herbivore.
An animal that eats a primary consumer or other consumer. They are carnivores or omnivores.
The predator at the top of the food chain
