Review

Herbivores are __________ that subsist on producers like plants and fungus.

72% Answer Correctly

	primary consumers
	scavengers
	tertiary consumers
	secondary consumers

Solution

Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.

In the classification of life, which of the following is not a kingdom?

63% Answer Correctly

	fungi
	plants
	bacteria
	animals

Solution

Below domain, life is classified into six kingdoms: plants, animals, archaebacteria, eubacteria, and fungi. The last kingdom, protists, include all microscopic organisms that are not bacteria, animals, plants or fungi. (Archaebacteria and eubacteria are sometimes combined into a single kingdom, monera.)

During continental drift, the drifting plates move across which of the following?

50% Answer Correctly

	water
	liquid mantle
	fault lines
	sediment

Solution

The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.

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

72% Answer Correctly

	secondary consumers
	decomposers
	producers
	primary 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

Which of the following is related to the Cambrian Explosion?

58% Answer Correctly

	extinction of dinosaurs
	carbon dating
	first civilizations
	fossil record

Solution

The Cambrian period is one of the most significant geological time periods. Lasting about 53 million years, it marked a dramatic burst of changes in life on Earth known as the Cambrian Explosion. It is from this period that the majority of the history of life on Earth, as documented by fossils, is found. Called the fossil record, the layering of these mineralized imprints of organisms preserved in sedementary rock have allowed geologists to build a historical record of plant and animal life on Earth.
