What in the World?
100
These factors in ecosystems can be living now, or could have been living at one time.
What is a biotic factor.
100
These factors in ecosystems are not alive and never have been.
What is an abiotic factor.
100

These are the three major cycles that move matter through ecosystems.

What are the water, nitrogen,  and carbon cycles.

100
This is used to show only one possible feeding relationship in an ecosystem.
What is a food chain.
100
This bird is designed to live in the antarctic only. What it lacks in its ability to fly, it makes up for in its ability to swim.
What is the emperor penguin.
200
This is an example of a biotic factor in a forest ecosystem. (Give one example)
What is...(numerous possibilities)?
200
This is an example of an abiotic factor in an ecosystem.
What is ....(numerous possibilities)?
200
This cycle moves matter through an ecosystem. This is taken in through photosynthesis and given off through respiration, combustion, and decomposition.
What is the carbon cycle?
200
This shows multiple feeding relationships in a particular ecosystem.
What is a food web?
200
This ecosystem covers over 70% of the Earth's surface. It is home to thousands of species.
What is the ocean ecosystem?
300

This biotic factor is considered the 'base' of every food chain because it can create its own energy.

What is a producer / autotroph

300
This abiotic factor provides a home for numerous species and is the main component of one of the four cycles we studied.
What is water?
300
One part of this cycle is called transpiration. This is when plants release this material through their leaves.
What is the water cycle?
300
This type of organism is the base of any food web or chain. If this was removed, all other organisms would collapse.
What is a producer?
300
This type of forest is located near the equator, gets a lot of rain annually, and is the home to millions of species.
What is the tropical rain forest?
400
These biotic factors are sometimes classified as primary, secondary, or tertiary when placed in a food web.
What is a consumer?
400
These two abiotic factors determine the types of plants that can survive in a particular environment.
What are soil and light?
400
This is a series of events that happen over and over again.
What is cycle?
400
Arrows are used in a food chain to represent the movement of this.
What is energy?
400
This desert producer has a very thick skin to help retain water and often comes equipped with spikes to deter other organisms from eating it.
What is a cactus?
500
This term describes any environment and all the living things that are supported by it.
What is an ecosystem?
500
This is the study of how organisms interact with both the living and non-living parts of their environment.
What is ecology?
500
This essential nutrient must be changed (fixed) before plants and animals can use it.
What is Nitrogen?
500
These organisms play an important role in any food chain or web by breaking down dead plant and animal matter into simpler compounds. One example is a mushroom.
What are decomposers?
500
This term describes large geographic areas that are similar in climate and have similar types of plants and animals. There are both land and aquatic ones.
What is a biome?
