100
This refers to all of the living and non-living things in an area, and all of their interactions.
What is Ecosystem.
100
The movement of oxygen and carbon dioxide on Earth through the process of photosynthesis and respiration
What is carbon dioxide-oxygen cycle.
100
A path of energy from ONE organism to ONE another.
What is a food chain.
100
Direct effect or change.
What is Impact.
100
An organism that gets energy by eating other organism.
What is a consumer.
200
Characterized by having a metabolism (means burn/use energy) and the ability to maintain a life process (born, have needs to survive, and die).
What is a living thing.
200
A gas produced by plants through photosynthesis.
What is Oxygen.
200
An organism that hunts and feeds on other organisms.
What is a predator.
200
All of the interacting members of the same species.
What is Population.
200
This symbol represents the transfer of energy in a Food Chain and Food Web.
What is an Arrow.
300
A part of the ecosystem that is not living, such as air, water, and sunlight.
What is a nonliving thing.
300
A gas produced by animals during respiration.
What is Carbon Dioxide.
300
An animal that is hunted as food.
What is Prey.
300
The maximum population size that can be sustained by a given environment.
What is Carrying Capacity.
300
Sunlight, water, rocks, and soil are all examples of this.
What are nonliving things.
400
A single, self-contained living thing.
What is an organism.
400
A process by which animals use oxygen and food to make carbon dioxide. (Hint: breathing)
What is Respiration.
400
An interconnected set of food chains.
What is a Food Web.
400
An increase in the number of individuals of a given species over what its ecosystem can sustain.
What is Overpopulation.
400
A layer of gases on Earth.
What is the atmosphere.
500
An organism that uses sunlight to make its own energy.
What is a producer.
500
The process where plants use sunlight, water, and carbon dioxide to produce sugar and release oxygen.
What is Photosynthesis.
500
All energy in a food chain/food web is derived from this.
What is the Sun.
500
The space, conditions, and all the living and nonliving things AROUND an organism.
What is Environment.
500
Plants use sunlight, water, and carbon dioxide to go through this process.
What is photosynthesis.
