What's the odd one out and why?
Paramecium
Bacteria
Cactus
Amoeba
What is a cactus?
All the others listed are unicellular and a cactus is multicellular.
The muscular system works closely with what other system to function?
What is the skeletal system? Because both systems work together to produce motion.
Where does digestion begin and end?
What is- It begins in the mouth and it ends in the large intestine?
True or false?
The heart, intestines, and lungs are all voluntary muscles.
What is- false?
They are all involuntary muscles because you do not have to THINK about them to use them.

What would most likely happen if all of the decomposers in an ecosystem were removed?
A) The animals in the ecosystem would die because of the spread of disease.
B) The plants in the ecosystem would eventually die because of a lack of nutrients in the soil.
C) The plants in the ecosystem would begin to die out because of a decrease in available water.
D) The animals in the ecosystem would eat other types of food because of a decrease in producers.
What is B- The plants in the ecosystem would eventually die because of a lack of nutrients in the soil?
