Ecosystems
These organisms, such as plants, make their own food using sunlight.
What are producers?
This biome is characterized by very low rainfall and extreme temperatures.
What is a desert?
This system is responsible for pumping blood and transporting oxygen throughout the body.
What is the circulatory system?
These are characteristics passed from parents to offspring through genes
What are inherited traits?
This model shows the overlapping food chains in an ecosystem.
What is a food web?
This group of organisms, including fungi and bacteria, breaks down dead organic matter.
What are decomposers?
This biome has four distinct seasons and trees that lose their leaves in the fall.
What is a deciduous forest?
This system takes in oxygen and removes carbon dioxide.
These are the three types of muscles found in the human body.
What is the respiratory system?
What are skeletal, smooth, and cardiac muscles?
These are natural behaviors animals are born with, like a baby bird knowing how to peck out of an egg.
What are instincts?

What is the tundra?
This system breaks down food into nutrients that the body can use for energy.
What is the digestive system?
This is the study of how traits are passed from parents to offspring through genes.
What is genetics?
This aquatic biome is where freshwater from a river meets the saltwater of the ocean.
What is an estuary?
This is the primary source of energy for almost all food chains on Earth.
What is the Sun?
This biome is often called the "lungs of the planet" due to its high density of trees and rainfall.
What is a tropical rainforest?
This system provides the body's framework and protects internal organs.
This is the main organ of the respiratory system where gas exchange occurs
What is the skeletal system?
What are the lungs?
These are skills acquired through experience or observing others, such as a dog learning to sit.
What is a learned behavior?
These are the two main types of aquatic biomes.
An organism that provides exactly half of the genetic information to its young is called this.
What are freshwater and saltwater (marine)?
What is a parent?
An animal that only eats other animals is known by this term.
What is a carnivore?
Large open areas of grass with few trees, often home to grazing animals, are called this.
What is a grassland (or savanna)?
This system consists of the brain, spinal cord, and nerves to control body activities.
This system allows the body to move and helps circulate blood.
What is the nervous system?
What is the muscular system?
This refers to the young produced by an organism.
What are offspring?
This type of trait is developed from environment or experience, like a scar from an injury
These are groups of individuals born around the same time, made up of offspring from the previous group.
What is an acquired trait?
What are generations?
