A reference to the amount of organisms that are able to live in a certain area of the environment.
What is Capacity?
100
A form of energy that is stored in fuels, food, and other chemicals.
What is Chemical energy?
100
A type of ecological relationship in which two or more organisms attempt to use the same resource.
What is Competition?
100
An organism that gets its energy by eating other organisms, also called a heterotroph.
What is Consumer?
100
__________ feed directly on plants; an example of this would be a mouse.
What are Primary consumers?
200
An organism in the food web that breaks down substances back into their basic chemical building blocks and puts them back in usable form into the environment.
What is Decomposer?
200
The paths that energy from the sun goes through from plants to animals.
What is Energy flow?
200
The process of converting energy from one form to another. An example is sunlight being used by a plant and changing to sugars.
What is Energy transformation?
200
Everything in an organism's surroundings. This includes living things (the biotic part of the environment) as well as the non-living things (the abiotic part of the environment).
What is Environment?
200
____________feed on second level consumers; an example of this would be a hawk eating the rattlesnake.
What are Tertiary consumers?
300
When a species no longer is in existence.
What is Extinction?
300
A representation showing the path of energy transfer within an ecosystem.
What is a Food chain?
300
A representation showing how energy moves through an ecosystem in a complex network of feeding relationships.
What is Food web?
300
The energy found in moving objects.
What is Mechanical energy?
300
Green plants, or _________ are capable of making their own food using energy from the sun in a process called photosynthesis.
What are Producers?
400
A type of ecological relationship that benefits all of the organisms involved.
What is Mutualism?
400
A type of ecological relationship in which one organism lives on or in another organism. The organism that lives on another organism absorbs nutrients from it.
What is Parasitism?
400
A chemical reaction that occurs in plants. Using light energy, plants change carbon dioxide (CO2) and water (H2O) to sugar (C6H12O6) and oxygen (O2).
What is Photosynthesis?
400
A type of ecological relationship in which one organism that kills and eats another organism.
What is a Predator?
400
A scientist who studies the plants of the rainforest.
What is a Botanist?
500
A type of ecological relationship in which this organism is killed and eaten by a predator.
What is Prey?
500
An organism that can make its own food from the sun's energy. It may also be called an autotroph. Generally such organisms are plants.
What is Producer?
500
The process of using oxygen (O2) to break down sugar (C6H12O6) into carbon dioxide (CO2) and water (H2O). This reaction is the opposite of photosynthesis. Instead of using energy, energy is given off.
What is Respiration?
500
Energy from the sun.
What is Solar energy?
500
A scientist who maps the rainforests of the world.
