Biotic/Abiotic
This is what we call all the living parts of an environment.
What is biotic?
This type of organism makes its own food using sunlight.
What is a producer?
This plant part takes in water and nutrients from the soil.
What are roots?
This landform is created when a river flows into a larger body of water and drops off sediment at the mouth of the river.
What is a delta?
This part of a frog’s life cycle is when it first hatches from an egg and swims in water.
What is a tadpole?
A deer drinks from a stream. This is an example of a biotic factor interacting with this type of factor.
What is an abiotic factor?
A lion eats other animals. That makes it this type of organism.
What is a consumer?
This structure in animals helps them move from one place to another.
What are legs (or wings, fins—accept reasonable answers)?
A canyon is most often formed by this slow process caused by moving water over many years.
What is erosion?
This is the stage of a turnip's life cycle when it begins to grow roots and leaves after being planted.
What is a seedling?
Trees provide shade for smaller plants. This is an interaction between two of these.
What are biotic factors?
These organisms break down dead plants and animals and return nutrients to the soil.
What are decomposers?
Leaves help a plant make food through this process.
What is photosynthesis?
Wind can move sand and build up these hills of sand in deserts or near beaches.
What are sand dunes?
A lady beetle starts as an egg, then becomes this stage where it looks like a small worm before turning into an adult.
What is larva?
This non-living factor affects where cacti can grow in the desert.
What is temperature (or sunlight)?
A rabbit eats grass. Is the rabbit a producer, consumer, or decomposer?
What is a consumer?
A turtle's hard shell protects it from predators. This is an example of a structure related to this function.
What is protection?
Which of the following landforms is created by deposition? A. Canyon B. Sand dune C. Earthquake fault D. Volcano
What is B. Sand dune?
After hatching from an egg, a frog spends time in water before growing legs and becoming this.
What is an adult frog?
In a forest, squirrels eat acorns, and birds build nests in trees. These are examples of biotic factors interacting with both biotic and abiotic factors. Name one biotic and one abiotic factor involved.
What are trees (biotic) and air (abiotic)? (Accept other correct combinations.)
Mushrooms grow on a rotting log and help break it down. What role are they playing in the ecosystem?
What is a decomposer?
A cactus has thick stems and a waxy coating. These structures help it survive in this type of environment.
What is a desert?
A delta forms where a river slows down and drops sediment. This is an example of which process?
What is deposition?
The lady beetle undergoes changes in its life cycle. Which stage comes after the larva and before the adult?
What is pupa?
