ECOLOGY - Energy Flow Menu - Food Webs

QuestionAnswer
Food chain Represents the transfer of energy from one organism to another in one direct line.
Food web Shows all of the energy transfers in an ecosystem (many interconnected chains).
Decomposer An organism that breaks down a dead material - such as bacteria, fungi, earthworms, and some insects.
Predator An animal that hunts, kills, and eats other animals to survive.
Prey An animal that the predators consume.
Consumer Any organism that eats food
Producer An organism that makes it's own food through photosynthesis - PLANTS
Carnivore A consumer that eats only meat
Herbivore A consumer that eats only plants
Omnivore A consumer that eats plants or meat
Photosynthesis A process whereby plants use light to synthesize (make) glucose (sugar) using carbon dioxide and water. [carbon dioxide + water = sugar + oxygen]
Chlorophyll A green chemical in a plant that is responsible for absorbing light energy for photosynthesis
Carbon dioxide A chemical that is made from carbon and oxygen that is the by-product (waste) of cellular respiration. It is also used by plants to make glucose (sugar).
Glucose Sugar (made during photosynthesis)
Oxygen A chemical that animals breath in for use in cellular respiration and plants give off as a waste
Bacteria Microorganisms that can decompose dead matter and can sometimes cause infectious diseases
Fungi A kingdom of organisms that decompose dead organisms; includes mushrooms and yeast.
Nitrogen A chemical that gets cycled in the environment and is necessary for protein building.
Energy pyramid Shows the flow of energy in an ecosystem - powered by the sun. Less energy is passed to each level going up.
Carbon A chemical that gets cycled from plants to animals during the process of cellular respiration and photosynthesis - a major component of sugar
Cellular Respiration A process in the cells where living things release the energy found in sugar (glucose)
Limiting Factor Anything that restricts the number of organisms that can live in an ecosystem (amount of food, predators, living space, etc.)
Energy Pyramid Shows the flow of energy in an ecosystem - powered by the sun. Less energy is passed to each level going up.
carrying capacity the maximum population of a certain species that can be supported by the resources in an environment. population usually goes up until it reaches this level. limiting factors will reduce this.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
