Solar System
This is a small piece of an asteroid or comet still in space.
What is a meteoroid?
This process happens when water moves INTO the ground.
What is infiltration?
This is the source of almost all energy on Earth.
What is the Sun?
This is the basic unit of structure and function in living things.
What is a cell?
This type of reproduction involves one parent.
What is asexual reproduction?
This force keeps planets orbiting around the Sun.
What is gravity?
The underground area where all spaces are filled with water is called this.
What is the saturated zone?
An organism that makes its own food is called this.
What is a producer?
Groups of similar cells form this.
What are tissues?
This type of reproduction creates genetic diversity.
What is sexual reproduction?
This is the region around the Sun where life can theoretically exist.
What is the habitable zone?
This term means the ground sinks due to water being removed underground.
What is subsidence?
Consumers that eat both plants and animals are called this.
What is a producer?
Several tissues working together form this.
What are organs?
Hydras reproduce this way.
What is budding?
This is the path a planet takes around the Sun.
What is an orbit?
This property describes how much empty space is found between particles in soil or rock.
What is porosity?
These organisms break down dead matter and recycle nutrients.
What are decomposers?
A group of organs working together forms this.
What is an organ system?
Farmers breeding cows that produce more milk is an example of this.
What is artificial selection?
Name TWO characteristics that help Earth support life.
Possible answers:
Explain the difference between porosity and permeability.
Porosity = amount of empty space
Permeability = how easily water can move through
What happens to a food web if one species is removed?
The ecosystem becomes unbalanced and other populations may increase or decrease.
Put these in order from smallest to largest:
Cells, organs, tissues, organism, organ systems
Cells → Tissues → Organs → Organ Systems → Organism
Birds with longer beaks surviving better in deep flowers is an example of this.
What is natural selection?
