What part of the food chain serves only as food for other organisms?

72% Answer Correctly

	primary consumers
	producers
	decomposers
	secondary consumers

Solution

Producers (autotrophs) serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis

Reproductive haploids are also known as:

62% Answer Correctly

	sperm
	ovum
	gametes
	diploids

Solution

Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.

Antigens in the blood determine:

52% Answer Correctly

	negative or positive status
	Rh factor
	blood oxygen capacity
	blood type

Solution

Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.

In the food chain, omnivores may be which of the following?

45% Answer Correctly

	secondary or tertiary consumers
	primary or secondary consumers
	primary or tertiary consumers
	secondary consumers or scavengers

Solution

Secondary or tertiary consumers may be omnivores.

Which of blood component carries oxygen?

84% Answer Correctly

	plasma
	red blood cells
	white blood cells
	platelets

Solution

Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.
