What is the difference between abiotic and biotic factors?
Biotic = living abiotic = not living

Decomposers
What is one reason engineers need to test their designs?
To find ways to improve them.
Which kingdom has one-celled organisms
Bacteria
Anything that slows or stops a population size from growing. Some examples of these are biotic like food competition with other organisms for resources. Others are abiotic, like space, temperature, and amount of sunlight available in an environment.
Limiting factors

Carnivore- eats only meat
Herbivore- eats on producers
Omnivore- eats both
