Flow of Matter
What do we call the transfer of food energy between organisms in an ecosystem?
Food Chain
True or False
Some invasive species have no effect on their new environment.
False
What do we call a living thing that must eat other living things for food?
A Consumer
Plants and other animals.
True or False:
Secondary consumers get their energy by eating animals that have already eaten plants.
True
What do we call a group of food chains that overlap?
Food Web
Which organism’s food source would most likely be the first to be affected by a drought (lack of rain in an area for a prolonged period of time)?
A mountain lion, an eagle, or a deer?
Deer
What is the difference between the different types of consumers: herbivores, omnivores, and Carnivores?
Herbivore=eats only plants, Omnivore=eats plants and other animals, Carnivore=eats only other animals
Herbivores (primary consumers) get their energy from_______.
Plants/Producers
What is the main source of energy for most ecosystems?
The Sun
In the matter cycle, what happens to the matter in dead plants and animals?
It is recycled by decomposers into the soil.
Which would most likely increase the number of squirrels living in an area?
reducing the number of animals that prey on bunnies.
What do we call a living thing that can make it's own food?
A Producer
What is the main source of energy for most ecosystems. (Hint: The first source of energy in a food chain or food web)
The Sun
The process of changing light energy to chemical energy?
Photosynthesis
Name the two ingredients (types of matter) all plants need to live.
Water & Carbon Dioxide
How do decomposers benefit an ecosystem?
They break down waste and dead organisms within the food chain.
This is the name given to the consumer that is at the end or top of a food chain or food web.
Tertiary Consumer/ Apex Predator
What do the arrows show in a food web?
The direction energy moves
What do plants take in from the air to help them grow?
Carbon Dioxide
What do we call a diagram that shows how energy is lost at each level in a food chain?
Energy Pyramid
In a food chain, hawks are consumers of snakes and rabbits. If the snake population suddenly decreases, what will most likely happen to the number of hawks?
The number of hawks will most likely decrease, because they will have less food available, making it harder for them to survive and reproduce.
What do we call a living thing that gets energy by breaking down dead organisms and wastes in simpler substances?
A Decomposer
Which group will Carnivores feed upon?
Decomposers, Producers, or Consumers.
Consumers
What does the law of conservation of energy say about energy?
Energy can change forms but can never be lost or destroyed.
